As of 2018-12-20, this bug affected ALL clusters created or imported by Rancher. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 提及了 "default namespace" 和 "pod",并且描述了通过将服务账户(service account)挂载到 pod 中,从而执行特权命令的问题。这表明它与 Kubernetes 的 namespace 和容器(pod)相关,同时也涉及权限隔离问题。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 该漏洞允许攻击者利用默认命名空间中的服务账户执行集群管理级别的特权命令。这意味着攻击者可能会影响整个 Kubernetes 集群中的其他容器或宿主机资源,具体取决于其获得的权限范围。因此,该漏洞确实可能导致一个容器(pod)影响其他容器或宿主机。 **结论**:满足条件 1 和 2。 cve: ./data/2018/20xxx/CVE-2018-20699.json Docker Engine before 18.09 allows attackers to cause a denial of service (dockerd memory consumption) via a large integer in a --cpuset-mems or --cpuset-cpus value, related to daemon/daemon_unix.go, pkg/parsers/parsers.go, and pkg/sysinfo/sysinfo.go. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 提到 Docker Engine 的 `--cpuset-mems` 和 `--cpuset-cpus` 参数,这些参数用于配置 cgroup 中的 CPU 和内存分配。因此,这个漏洞与 cgroup 和容器的资源限制机制直接相关。 2. **分析是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 该漏洞允许攻击者通过提供一个大整数来触发 DoS(拒绝服务),导致 `dockerd` 进程消耗大量内存。这种行为会影响整个 Docker 守护进程,可能会间接影响其他正在运行的容器和宿主机的稳定性。因此,该漏洞确实可能导致容器运行时影响其他容器或宿主机。 **结论**:条件 1 和 2 均满足。 cve: ./data/2018/20xxx/CVE-2018-20871.json In Univa Grid Engine before 8.6.3, when configured for Docker jobs and execd spooling on root_squash, weak file permissions ("other" write access) occur in certain cases (GE-6890). analysis: ### 分析结果: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: - 是的,该CVE信息明确提到Univa Grid Engine在配置为运行Docker任务时,存在文件权限问题。这表明它与容器(Docker)相关,并且可能涉及容器的执行环境和文件系统隔离。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: - 可能会。由于文件权限被错误地设置为“其他用户可写”("other" write access),攻击者可能利用此漏洞修改关键文件,进而影响其他容器或宿主机的安全性。这种弱权限问题通常会导致隔离性的破坏,使攻击者能够逃逸容器环境或篡改宿主机上的资源。 ### 结论: 满足条件1和条件2,因此返回分析内容。 cve: ./data/2018/6xxx/CVE-2018-6552.json Apport does not properly handle crashes originating from a PID namespace allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion, possibly gain root privileges, or escape from containers. The is_same_ns() function returns True when /proc// does not exist in order to indicate that the crash should be handled in the global namespace rather than inside of a container. However, the portion of the data/apport code that decides whether or not to forward a crash to a container does not always replace sys.argv[1] with the value stored in the host_pid variable when /proc// does not exist which results in the container pid being used in the global namespace. This flaw affects versions 2.20.8-0ubuntu4 through 2.20.9-0ubuntu7, 2.20.7-0ubuntu3.7, 2.20.7-0ubuntu3.8, 2.20.1-0ubuntu2.15 through 2.20.1-0ubuntu2.17, and 2.14.1-0ubuntu3.28. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 描述中明确提到 PID namespace 和容器(container)的概念,并且提到了由于 `/proc//` 的处理问题,可能导致 crash 被错误地处理在全局命名空间(global namespace)而不是容器内部。因此,该问题与 namespace 和容器隔离机制密切相关。 2. **分析是否会导致容器运行时影响其他容器或宿主机**: 根据描述,攻击者可能利用此漏洞通过资源耗尽(denial of service via resource exhaustion)或获取 root 权限(gain root privileges),甚至逃逸出容器(escape from containers)。这表明该漏洞确实会影响容器的隔离性,并可能导致容器逃逸,从而影响其他容器或宿主机的安全。 3. **结论**: 该 CVE 满足条件 1 和条件 2,因此需要返回具体的分析结果,而不是 "N/A"。 cve: ./data/2018/6xxx/CVE-2018-6559.json The Linux kernel, as used in Ubuntu 18.04 LTS and Ubuntu 18.10, allows local users to obtain names of files in which they would not normally be able to access via an overlayfs mount inside of a user namespace. analysis: ### 分析结果: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该CVE涉及`user namespace`和`overlayfs`。`user namespace`是Linux内核中用于隔离用户和组ID的命名空间机制,常用于容器技术(如Docker)中实现用户隔离。`overlayfs`是一种联合文件系统,广泛用于容器镜像的分层存储。因此,这个漏洞与容器隔离机制相关。 2. **是否会导致容器在运行时影响其他容器或宿主机:** 是的,该漏洞允许本地用户通过`overlayfs`挂载点,在`user namespace`中访问到他们本不应访问的文件路径信息。这种信息泄露可能被攻击者利用来进一步突破容器隔离,进而影响其他容器或宿主机的安全性。 ### 结论: 该CVE与容器隔离机制相关,并可能导致容器运行时影响其他容器或宿主机。 cve: ./data/2018/7xxx/CVE-2018-7169.json An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths if the administrator has used "group blacklisting" (e.g., chmod g-rwx) to restrict access to paths. This flaw effectively reverts a security feature in the kernel (in particular, the /proc/self/setgroups knob) to prevent this sort of privilege escalation. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该 CVE 信息与 namespace 相关。具体来说,问题涉及 `newgidmap` 工具在 user namespace 中的行为,以及 `/proc/self/setgroups` 内核功能对 group 权限的控制。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 可能会。由于该漏洞允许非特权用户通过 user namespace 移除自己所属的 supplementary group,这可能导致容器内的攻击者绕过某些基于 group 的文件系统访问限制。如果容器依赖 "group blacklisting" 来限制对某些敏感路径的访问,这种绕过可能会影响宿主机或其他容器的安全性。 **结论**:满足条件 1 和 2,因此返回分析结果。 cve: ./data/2018/7xxx/CVE-2018-7480.json The blkcg_init_queue function in block/blk-cgroup.c in the Linux kernel before 4.11 allows local users to cause a denial of service (double free) or possibly have unspecified other impact by triggering a creation failure. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关:** 该 CVE 提及了 `blkcg_init_queue` 函数,该函数位于 `block/blk-cgroup.c` 文件中。`blk-cgroup` 是 Linux 内核中的块设备控制组(cgroup)子系统的一部分,用于对块设备 I/O 进行资源限制和管理。因此,该问题与 cgroup 直接相关。 2. **分析是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 由于该漏洞涉及 cgroup 的实现,而 cgroup 是容器技术(如 Docker)实现资源隔离的核心机制之一,因此该漏洞可能会影响容器的隔离性。如果攻击者能够在容器内触发此漏洞(例如通过特定的 I/O 操作),可能会导致宿主机上的资源管理失效,甚至可能引发宿主机崩溃(拒绝服务攻击)。此外,虽然具体的 "unspecified other impact" 未明确描述,但理论上也可能存在进一步的权限提升或其他安全风险。 **结论:** 该 CVE 与 cgroup 和容器隔离相关,并且可能导致容器运行时影响其他容器或宿主机。 cve: ./data/2018/9xxx/CVE-2018-9862.json util.c in runV 1.0.0 for Docker mishandles a numeric username, which allows attackers to obtain root access by leveraging the presence of an initial numeric value on an /etc/passwd line, and then issuing a "docker exec" command with that value in the -u argument, a similar issue to CVE-2016-3697. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与容器技术相关。具体来说,它影响 Docker 的 `docker exec` 命令,涉及用户 ID 的处理问题。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机:** 是的,该漏洞可能导致容器内的攻击者通过错误处理的用户 ID 获得 root 权限。如果攻击者在容器内利用此漏洞获得 root 权限,他们可能进一步突破容器隔离,影响宿主机或其他容器的安全性。 3. **结论:** 由于条件 1 和 2 都满足,因此需要返回分析结果而非 "N/A"。 cve: ./data/2019/0xxx/CVE-2019-0204.json A specifically crafted Docker image running under the root user can overwrite the init helper binary of the container runtime and/or the command executor in Apache Mesos versions pre-1.4.x, 1.4.0 to 1.4.2, 1.5.0 to 1.5.2, 1.6.0 to 1.6.1, and 1.7.0 to 1.7.1. A malicious actor can therefore gain root-level code execution on the host. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息明确提到了Docker镜像和容器运行时(container runtime),并且涉及Apache Mesos中的容器管理功能。这表明它与容器技术及隔离机制密切相关。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞允许攻击者通过精心构造的Docker镜像覆盖容器运行时的关键二进制文件(如init helper binary或command executor)。一旦成功,攻击者可以获得宿主机的root级代码执行权限,从而完全突破容器隔离,影响宿主机和其他运行在其上的容器。 **结论**: 该CVE满足条件1和条件2,因此不会返回"N/A"。 cve: ./data/2019/10xxx/CVE-2019-10147.json rkt through version 1.30.0 does not isolate processes in containers that are run with `rkt enter`. Processes run with `rkt enter` are not limited by cgroups during stage 2 (the actual environment in which the applications run). Compromised containers could exploit this flaw to access host resources. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息明确提到`rkt`在使用`rkt enter`命令时,没有正确隔离容器中的进程。此外,还提到这些进程在stage 2阶段不受cgroups限制,这直接影响了容器的资源隔离机制。 2. **是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 是的,由于进程在使用`rkt enter`时未被正确隔离且不受cgroups限制,攻击者可以利用此漏洞访问宿主机资源,从而可能影响宿主机或其他容器的安全性。 **结论**:满足条件1和条件2。 cve: ./data/2019/10xxx/CVE-2019-10175.json A flaw was found in the containerized-data-importer in virt-cdi-cloner, version 1.4, where the host-assisted cloning feature does not determine whether the requesting user has permission to access the Persistent Volume Claim (PVC) in the source namespace. This could allow users to clone any PVC in the cluster into their own namespace, effectively allowing access to other user's data. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与 namespace 和容器隔离相关。问题出在 containerized-data-importer 的 host-assisted cloning 功能中,未正确验证用户对源 namespace 中 Persistent Volume Claim (PVC) 的访问权限。这表明了跨 namespace 的访问控制存在问题,影响了容器环境中的隔离性。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 是的,此漏洞可能导致一个用户克隆其他用户在不同 namespace 下的 PVC,从而获取其他用户的数据。这种行为破坏了容器和 namespace 之间的隔离性,可能间接影响其他容器或宿主机的安全性,因为敏感数据可能会被泄露。 **结论:满足条件 1 和 2。** cve: ./data/2019/10xxx/CVE-2019-10639.json The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 相关。具体来说,攻击利用了 IP ID 生成机制的变化,而这种变化依赖于与网络命名空间(network namespace)相关的地址。网络命名空间是 Linux 容器(如 Docker)实现网络隔离的核心技术之一。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 该漏洞可能导致 KASLR(Kernel Address Space Layout Randomization)被绕过,从而暴露内核镜像的偏移量。虽然该漏洞本身不会直接破坏容器的隔离性,但它可以为后续的攻击提供便利(例如,通过暴露内核地址信息帮助提权攻击)。如果攻击者能够利用此漏洞获取宿主机内核的地址信息,并结合其他漏洞进行提权,则可能会影响其他容器或宿主机的安全性。 3. **结论:** 由于条件 1 和条件 2 均满足,因此需要返回上述分析内容,而不是 "N/A"。 cve: ./data/2019/11xxx/CVE-2019-11247.json The Kubernetes kube-apiserver mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges). Kubernetes affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.7, 1.8, 1.9, 1.10, 1.11, 1.12. analysis: 1. 该 CVE 信息与 namespace 相关。问题的核心是 kube-apiserver 错误地允许对集群范围(cluster-scoped)的自定义资源进行访问,前提是请求是以资源为命名空间范围(namespaced)的方式发起的。这涉及到 Kubernetes 的权限控制机制中关于命名空间的角色和角色绑定。 2. 该 CVE 不会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机。此漏洞主要影响 Kubernetes API 的权限管理机制,使得具有特定命名空间权限的用户可以越权访问集群范围的资源。它并不直接影响容器的隔离性或宿主机的安全性。 结论:不满足条件 2,但满足条件 1,因此返回分析结果。 cve: ./data/2019/11xxx/CVE-2019-11815.json An issue was discovered in rds_tcp_kill_sock in net/rds/tcp.c in the Linux kernel before 5.0.8. There is a race condition leading to a use-after-free, related to net namespace cleanup. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 信息明确提到与 `net namespace` 清理相关的竞争条件问题。`net namespace` 是 Linux 命名空间的一种,用于实现网络资源的隔离,是容器技术(如 Docker)中网络隔离的重要组成部分。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,由于该漏洞涉及 `net namespace` 的清理过程中的竞争条件,可能导致使用后释放(use-after-free)问题。如果攻击者能够触发这一漏洞,可能会利用它破坏容器的网络隔离,进而影响其他容器或宿主机的安全性。 **结论**:满足条件 1 和条件 2。 cve: ./data/2019/12xxx/CVE-2019-12670.json A vulnerability in the filesystem of Cisco IOS XE Software could allow an authenticated, local attacker within the IOx Guest Shell to modify the namespace container protections on an affected device. The vulnerability is due to insufficient file permissions. An attacker could exploit this vulnerability by modifying files that they should not have access to. A successful exploit could allow the attacker to remove container protections and perform file actions outside the namespace of the container. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE明确提到了“namespace container protections”和“container”,并且描述了攻击者可以通过修改文件权限来移除容器的保护机制,并在容器的命名空间之外执行文件操作。这直接涉及容器的隔离机制。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,由于该漏洞允许攻击者移除容器的保护并执行超出容器命名空间的操作,因此攻击者可能会影响其他容器或宿主机。具体来说,攻击者可以在宿主机上进行未授权的文件操作,从而破坏隔离性,进一步可能导致宿主机或其他容器被攻击。 3. **结论**: 条件1和条件2均满足,因此返回上述分析结果。 cve: ./data/2019/12xxx/CVE-2019-12674.json Multiple vulnerabilities in the multi-instance feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to escape the container for their FTD instance and execute commands with root privileges in the host namespace. These vulnerabilities are due to insufficient protections on the underlying filesystem. An attacker could exploit these vulnerabilities by modifying critical files on the underlying filesystem. A successful exploit could allow the attacker to execute commands with root privileges within the host namespace. This could allow the attacker to impact other running FTD instances. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息明确提到“escape the container”以及“host namespace”,表明漏洞与容器和命名空间的隔离机制直接相关。 2. **是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 是的,根据描述,攻击者可以通过修改底层文件系统的关键文件,逃逸出其所在的FTD实例容器,并在宿主机的命名空间中以root权限执行命令。这不仅会影响宿主机,还可能影响其他正在运行的FTD实例。 3. **结论**: 条件1和条件2均满足,因此返回分析结果。 cve: ./data/2019/12xxx/CVE-2019-12675.json Multiple vulnerabilities in the multi-instance feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, local attacker to escape the container for their FTD instance and execute commands with root privileges in the host namespace. These vulnerabilities are due to insufficient protections on the underlying filesystem. An attacker could exploit these vulnerabilities by modifying critical files on the underlying filesystem. A successful exploit could allow the attacker to execute commands with root privileges within the host namespace. This could allow the attacker to impact other running FTD instances. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息明确提到“escape the container for their FTD instance”,即攻击者可以逃逸出其FTD实例的容器,并且提到“execute commands with root privileges in the host namespace”,这表明问题涉及容器与宿主机命名空间之间的隔离。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,根据描述,“A successful exploit could allow the attacker to execute commands with root privileges within the host namespace. This could allow the attacker to impact other running FTD instances.” 这说明攻击者成功利用漏洞后,可以在宿主机的命名空间中执行命令,从而影响其他正在运行的FTD实例(容器)。此外,由于获得了宿主机的root权限,理论上也可能影响宿主机本身和其他非FTD相关的容器。 **结论**:满足条件1和条件2。 cve: ./data/2019/12xxx/CVE-2019-12825.json Unauthorized Access to the Container Registry of other groups was discovered in GitLab Enterprise 12.0.0-pre. In other words, authenticated remote attackers can read Docker registries of other groups. When a legitimate user changes the path of a group, Docker registries are not adapted, leaving them in the old namespace. They are not protected and are available to all other users with no previous access to the repo. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该CVE与容器相关。问题涉及Docker registry的访问控制,具体是由于组路径更改后,Docker镜像仓库未正确更新到新的命名空间(namespace),导致旧的命名空间中的资源未被正确保护。 2. **是否会导致容器在运行时影响其他容器或宿主机** 该漏洞不会直接影响容器的运行时行为,也不会直接影响其他容器或宿主机的安全性。然而,它会导致未经授权的用户访问其他组的Docker镜像仓库,从而可能泄露敏感信息(如镜像内容、构建配置等)。这种信息泄露可能间接为攻击者提供进一步攻击的素材,但本身并不直接破坏容器隔离或宿主机安全。 **结论**:满足条件1,不满足条件2。 cve: ./data/2019/13xxx/CVE-2019-13139.json In Docker before 18.09.4, an attacker who is capable of supplying or manipulating the build path for the "docker build" command would be able to gain command execution. An issue exists in the way "docker build" processes remote git URLs, and results in command injection into the underlying "git clone" command, leading to code execution in the context of the user executing the "docker build" command. This occurs because git ref can be misinterpreted as a flag. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该CVE与容器技术相关。它涉及Docker的`docker build`命令,该命令用于构建容器镜像。问题出现在处理远程Git URL的方式上,可能导致命令注入。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机:** 该漏洞不会直接影响其他容器或宿主机的隔离性。然而,由于命令注入发生在执行`docker build`的用户上下文中,攻击者可能利用此漏洞以执行任意代码,从而潜在地影响宿主机或其他资源(取决于执行`docker build`的用户权限)。因此,虽然不是直接破坏容器隔离,但它可能间接影响宿主机的安全性。 **结论:** 不完全满足条件2(直接影响其他容器或宿主机隔离),但与容器技术相关。返回分析结果即可,不适用"N/A"。 cve: ./data/2019/13xxx/CVE-2019-13509.json In Docker CE and EE before 18.09.8 (as well as Docker EE before 17.06.2-ee-23 and 18.x before 18.03.1-ee-10), Docker Engine in debug mode may sometimes add secrets to the debug log. This applies to a scenario where docker stack deploy is run to redeploy a stack that includes (non external) secrets. It potentially applies to other API users of the stack API if they resend the secret. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该 CVE 与容器技术(Docker)相关。它描述了 Docker Engine 在调试模式下可能将敏感信息(如 secrets)记录到调试日志中的问题。虽然这不是直接与 namespace 或 cgroup 隔离机制相关的问题,但它确实涉及容器管理功能(stack deploy 和 secrets 管理),因此与容器技术密切相关。 2. **是否会导致容器运行时影响其他容器或宿主机:** 这个 CVE 不会直接影响其他容器或宿主机的安全性。它的主要风险在于泄露敏感信息(如 secrets),这些信息可能会通过调试日志被未经授权的用户访问。然而,这种泄露的前提是攻击者已经能够访问调试日志文件。如果调试日志被妥善保护,这种风险可以被有效控制。因此,它不会直接导致容器之间的隔离失效或对宿主机造成直接影响。 3. **结论:** 根据上述分析,条件 1 满足,条件 2 不满足,因此返回以下分析结果: - 与容器技术相关,但不会直接影响其他容器或宿主机。 - 主要风险为敏感信息泄露,需确保调试日志的安全性。 cve: ./data/2019/14xxx/CVE-2019-14271.json In Docker 19.03.x before 19.03.1 linked against the GNU C Library (aka glibc), code injection can occur when the nsswitch facility dynamically loads a library inside a chroot that contains the contents of the container. analysis: ### 分析结果: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE明确提到了Docker,并且涉及容器的运行环境。具体来说,问题发生在nsswitch设施在chroot环境中动态加载库时,而chroot通常用于容器的隔离机制中。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致代码注入。如果攻击者能够利用此漏洞在容器内注入恶意代码,并且该代码能够在宿主机的上下文中执行(由于动态加载库的行为),那么这将突破容器的隔离性,进而可能影响其他容器或宿主机的安全。 ### 结论: 该CVE满足条件1和条件2,因此不会返回"N/A"。 cve: ./data/2019/14xxx/CVE-2019-14806.json Pallets Werkzeug before 0.15.3, when used with Docker, has insufficient debugger PIN randomness because Docker containers share the same machine id. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 提及了 Docker 容器,并指出由于 Docker 容器共享相同的 `machine id`,导致调试器 PIN 的随机性不足。这表明问题与容器环境及其隔离机制相关。 2. **分析是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 是的,由于调试器 PIN 随机性不足,攻击者可能利用这一点在共享相同 `machine id` 的容器中进行未授权访问或其他恶意操作。这种漏洞可能允许一个容器影响其他容器或甚至影响宿主机的安全性。 3. **结论**: 条件 1 和 2 均满足,因此需要返回上述分析内容,而不是 "N/A"。 cve: ./data/2019/14xxx/CVE-2019-14819.json A flaw was found during the upgrade of an existing OpenShift Container Platform 3.x cluster.

Kernel 3.10.x and 4.18.x branches are believed to be vulnerable. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 提及了 cgroups 子系统。具体来说,问题是由于 SCTP socket buffer 没有被 cgroups 正确计入资源限制。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 可能会。由于 cgroups 是 Linux 容器(如 Docker)中用于实现资源限制和隔离的核心机制之一,如果 SCTP socket buffer 的使用未被正确计入 cgroups,攻击者可能利用此漏洞绕过资源限制(例如内存限制),从而影响同一宿主机上的其他容器或宿主机本身的稳定性。这种行为可能导致拒绝服务(Denial of Service, DoS)攻击。 3. **结论:** 该 CVE 信息满足条件 1 和条件 2。 cve: ./data/2019/3xxx/CVE-2019-3884.json A vulnerability exists in the garbage collection mechanism of atomic-openshift. An attacker able spoof the UUID of a valid object from another namespace is able to delete children of those objects. Versions 3.6, 3.7, 3.8, 3.9, 3.10, 3.11 and 4.1 are affected. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞与namespace相关。描述中提到攻击者可以通过伪造另一个namespace中有效对象的UUID来删除该对象的子资源。这表明漏洞涉及跨namespace的操作。 2. **是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 从描述来看,该漏洞主要影响OpenShift中的垃圾回收机制,并允许攻击者通过伪造UUID跨namespace删除资源。虽然它没有直接提及容器或其隔离性被破坏,但因为涉及到namespace的跨越操作,可能会间接影响到容器的资源管理或依赖的资源,从而对其他容器或宿主机产生潜在影响。 **结论**:满足条件1和2,需注意此漏洞可能带来的跨namespace资源删除风险以及对容器环境的间接影响。 cve: ./data/2019/5xxx/CVE-2019-5021.json Versions of the Official Alpine Linux Docker images (since v3.3) contain a NULL password for the `root` user. This vulnerability appears to be the result of a regression introduced in December of 2015. Due to the nature of this issue, systems deployed using affected versions of the Alpine Linux container which utilize Linux PAM, or some other mechanism which uses the system shadow file as an authentication database, may accept a NULL password for the `root` user. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器相关。它明确提到了 Alpine Linux Docker 镜像中存在一个问题,影响基于这些镜像构建的容器。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 是的,这个问题可能会导致容器在运行时影响宿主机或其他容器的安全性。由于 `root` 用户的密码为空,攻击者可以轻松获得容器内的 root 权限。如果容器的配置允许访问宿主机资源(例如通过共享命名空间、挂载宿主机目录等),攻击者可能进一步利用此漏洞危害宿主机或与其他容器交互。 **结论**:满足条件 1 和 2。 cve: ./data/2019/5xxx/CVE-2019-5736.json runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与容器技术直接相关。它影响 `runc`(一个用于创建和运行 OCI 容器的主要工具),并且问题涉及容器内的文件描述符处理不当,可能导致宿主机上的 `runc` 二进制文件被覆盖。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 是的,该漏洞允许攻击者通过在容器内执行特定操作来覆盖宿主机上的 `runc` 二进制文件,从而获得宿主机的 root 权限。这将直接影响宿主机的安全性,并可能间接影响其他在该宿主机上运行的容器。 3. **结论:** 由于条件 1 和 2 都满足,因此返回上述分析结果。 cve: ./data/2019/6xxx/CVE-2019-6287.json In Rancher 2.0.0 through 2.1.5, project members have continued access to create, update, read, and delete namespaces in a project after they have been removed from it. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该CVE与namespace相关。描述中明确提到“project members”在被移除后仍然可以对项目中的namespaces进行创建、更新、读取和删除操作。Namespace是容器技术(如Docker)中用于实现资源隔离的重要组成部分。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机:** 从描述来看,此漏洞主要影响的是Rancher管理平台的权限控制机制,而不是容器运行时的隔离性本身。虽然它允许未经授权的用户操作namespaces,但并没有直接提到这种操作会对其他容器或宿主机的安全性造成直接影响。然而,间接上,如果攻击者滥用此漏洞来恶意操作namespaces,可能会导致服务中断或其他安全问题。 3. **结论:** 根据以上分析,条件1满足,因此返回分析结果而非"N/A"。 cve: ./data/2020/10xxx/CVE-2020-10676.json In Rancher 2.x before 2.6.13 and 2.7.x before 2.7.4, an incorrectly applied authorization check allows users who have certain access to a namespace to move that namespace to a different project. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与 namespace 相关。描述中明确提到 "namespace",并且问题涉及用户可以将某个 namespace 移动到不同的项目中。Namespace 是容器技术(如 Docker)中用于实现资源隔离的重要组成部分。 2. **分析是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 这个 CVE 的影响主要体现在 Rancher 的权限管理上。由于授权检查错误,拥有某些权限的用户可以将一个 namespace 移动到另一个项目中。这种操作可能会导致以下潜在风险: - 如果目标项目中的安全策略较松散,可能会间接影响该 namespace 下运行的容器的安全性。 - 在多租户环境中,这种行为可能破坏预期的隔离边界,导致敏感信息泄露或权限提升。 - 虽然直接危害宿主机的可能性较低,但通过改变 namespace 的归属关系,攻击者可能进一步利用其他漏洞扩大影响范围。 因此,这个 CVE 的确可能间接影响容器之间的隔离性,尤其是在多租户场景下。 **结论**:满足条件 1 和 2。 cve: ./data/2020/10xxx/CVE-2020-10689.json A flaw was found in the Eclipse Che up to version 7.8.x, where it did not properly restrict access to workspace pods. An authenticated user can exploit this flaw to bypass JWT proxy and gain access to the workspace pods of another user. Successful exploitation requires knowledge of the service name and namespace of the target pod. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器和命名空间相关。Eclipse Che 是一个基于容器的工作区开发环境,问题涉及对工作区 Pods(容器)的访问控制不当。Pods 是 Kubernetes 中的容器集合,而命名空间(namespace)是 Kubernetes 中用于隔离资源的概念。因此,该漏洞直接涉及容器和命名空间。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致影响其他容器。由于访问控制不足,攻击者可以通过此漏洞访问其他用户的 workspace pods,从而可能获取敏感信息或执行未经授权的操作。虽然该漏洞本身没有明确提到直接影响宿主机,但通过访问其他用户的工作区 Pods,攻击者可能会进一步利用其他漏洞来威胁宿主机的安全性。 **结论**:满足条件 1 和 2。 cve: ./data/2020/11xxx/CVE-2020-11492.json An issue was discovered in Docker Desktop through 2.2.0.5 on Windows. If a local attacker sets up their own named pipe prior to starting Docker with the same name, this attacker can intercept a connection attempt from Docker Service (which runs as SYSTEM), and then impersonate their privileges. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 该CVE描述了在Docker Desktop for Windows中,通过创建同名的命名管道(named pipe),攻击者可以拦截Docker Service的连接尝试。此问题主要涉及Docker服务的权限管理和通信机制,而不是直接与namespace、cgroup、容器隔离机制相关。 2. **分析是否会导致容器影响其他容器或宿主机**: 该漏洞允许本地攻击者拦截Docker Service的连接,并利用其SYSTEM权限进行特权提升。这可能间接影响到宿主机的安全性,但并不直接影响其他容器的运行或隔离性。问题的核心在于Docker Service本身的权限管理漏洞,而非容器间的交互或隔离机制。 **结论**:N/A cve: ./data/2020/12xxx/CVE-2020-12114.json A pivot_root race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before 4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a denial of service (panic) by corrupting a mountpoint reference counter. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该 CVE 信息与 namespace 相关。`pivot_root` 是一个与 Linux 命名空间(namespace)密切相关的系统调用,通常用于更改根文件系统,尤其是在容器化环境中初始化容器的根文件系统时。此外,问题出现在 `fs/namespace.c` 文件中,进一步表明它与命名空间机制有关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,可能会对容器环境产生影响。由于 `pivot_root` 的竞争条件可能导致内核崩溃(panic),如果攻击者能够在容器内利用此漏洞,则可能破坏宿主机的稳定性,从而间接影响同一宿主机上的其他容器。虽然容器本身提供了一定的隔离性,但这种内核级别的漏洞可能会突破隔离,导致更广泛的影响。 **结论**:满足条件 1 和 2,因此需要进行上述分析。 cve: ./data/2020/13xxx/CVE-2020-13401.json An issue was discovered in Docker Engine before 19.03.11.

This issue could allow a malicious or compromised container to compromise the container host and other containers running on the same host. This issue only affects docker version 1.13.1-108.git4ef4b30.el7, shipped in Red Hat Enterprise Linux 7 Extras. Both earlier and later versions are not affected. analysis: 1. 该 CVE 信息与 namespace、cgroup、container 或容器隔离相关。 - 描述中明确提到 "runc" 和 "container host",并且问题涉及容器的运行时环境。 2. 该 CVE 可能会导致容器(例如 Docker)在运行时影响其他容器或宿主机。 - 描述中提到 "a malicious or compromised container to compromise the container host and other containers running on the same host",表明恶意或被攻陷的容器可以影响宿主机和其他容器。 **结论:满足条件 1 和 2。** cve: ./data/2020/14xxx/CVE-2020-14300.json The docker packages version docker-1.13.1-108.git4ef4b30.el7 as released for Red Hat Enterprise Linux 7 Extras via RHBA-2020:0053 (https://access.redhat.com/errata/RHBA-2020:0053) included an incorrect version of runc that was missing multiple bug and security fixes. One of the fixes regressed in that update was the fix for CVE-2016-9962, that was previously corrected in the docker packages in Red Hat Enterprise Linux 7 Extras via RHSA-2017:0116 (https://access.redhat.com/errata/RHSA-2017:0116). The CVE-2020-14300 was assigned to this security regression and it is specific to the docker packages produced by Red Hat. The original issue - CVE-2016-9962 - could possibly allow a process inside container to compromise a process entering container namespace and execute arbitrary code outside of the container. This could lead to compromise of the container host or other containers running on the same container host. This issue only affects a single version of Docker, 1.13.1-108.git4ef4b30, shipped in Red Hat Enterprise Linux 7. Both earlier and later versions are not affected. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息明确提到“process inside container”和“container namespace”,这表明问题与容器的命名空间(namespace)机制有关,涉及容器的隔离特性。 2. **分析是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,根据描述,CVE-2016-9962(该漏洞的原始问题)可能允许容器内的进程“compromise a process entering container namespace and execute arbitrary code outside of the container”。这意味着攻击者可以利用此漏洞突破容器隔离,执行任意代码,从而危及宿主机或其他在同一宿主机上运行的容器。 3. **结论**: 由于条件1和条件2均满足,因此返回上述分析内容。 cve: ./data/2020/14xxx/CVE-2020-14306.json An incorrect access control flaw was found in the operator, openshift-service-mesh/istio-rhel8-operator all versions through 1.1.3. This flaw allows an attacker with a basic level of access to the cluster to deploy a custom gateway/pod to any namespace, potentially gaining access to privileged service account tokens. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 和容器隔离相关。问题在于 OpenShift Service Mesh 的 Operator 中存在访问控制漏洞,允许攻击者在任何 namespace 下部署自定义网关或 Pod。Namespace 是 Kubernetes 中用于隔离资源的核心概念之一,因此此漏洞直接影响了 namespace 的隔离性。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 是的,此漏洞可能导致容器影响其他容器或宿主机。攻击者可以利用此漏洞在未经授权的 namespace 中部署恶意 Pod,这些 Pod 可能会进一步访问其他 Pod、服务账户令牌或其他敏感资源。此外,如果攻击者获取了特权服务账户令牌,他们可能会对整个集群(包括宿主机和其他容器)造成更广泛的影响。 **结论:** 满足条件 1 和 2,因此返回上述分析结果。 cve: ./data/2020/14xxx/CVE-2020-14356.json A flaw null pointer dereference in the Linux kernel cgroupv2 subsystem in versions before 5.7.10 was found in the way when reboot the system. A local user could use this flaw to crash the system or escalate their privileges on the system. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 明确提到了 cgroupv2 子系统,因此与 cgroup 相关。Cgroup 是容器技术(如 Docker)中用于资源限制和隔离的重要组成部分,因此也间接与容器和隔离相关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 由于该漏洞存在于 cgroupv2 子系统中,并且可能导致系统崩溃或权限提升,如果攻击者能够在容器内触发此漏洞,则可能会影响宿主机的稳定性或安全性。这可能会进一步影响同一宿主机上的其他容器,或者被利用来突破容器隔离,从而对宿主机或其他容器造成威胁。 3. **结论**: 条件 1 和条件 2 均满足,因此返回分析结果而非 "N/A"。 cve: ./data/2020/14xxx/CVE-2020-14370.json An information disclosure vulnerability was found in containers/podman in versions before 2.0.5. When using the deprecated Varlink API or the Docker-compatible REST API, if multiple containers are created in a short duration, the environment variables from the first container will get leaked into subsequent containers. An attacker who has control over the subsequent containers could use this flaw to gain access to sensitive information stored in such variables. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE明确提到containers/podman中的问题,涉及容器环境变量的泄露。Podman是一个容器运行时工具,因此该问题与容器和隔离机制直接相关。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器之间的信息泄露。具体来说,当使用特定API创建多个容器时,第一个容器的环境变量可能会泄露到后续创建的容器中。如果攻击者能够控制这些后续容器,就可以获取敏感信息,从而影响其他容器的安全性。虽然这不会直接影响宿主机,但泄露的信息可能被利用来进一步攻击宿主机或其他系统组件。 **结论**:满足条件1和条件2。 cve: ./data/2020/15xxx/CVE-2020-15157.json In containerd (an industry-standard container runtime) before version 1.2.14 there is a credential leaking vulnerability. If a container image manifest in the OCI Image format or Docker Image V2 Schema 2 format includes a URL for the location of a specific image layer (otherwise known as a “foreign layer”), the default containerd resolver will follow that URL to attempt to download it. In v1.2.x but not 1.3.0 or later, the default containerd resolver will provide its authentication credentials if the server where the URL is located presents an HTTP 401 status code along with registry-specific HTTP headers. If an attacker publishes a public image with a manifest that directs one of the layers to be fetched from a web server they control and they trick a user or system into pulling the image, they can obtain the credentials used for pulling that image. In some cases, this may be the user's username and password for the registry. In other cases, this may be the credentials attached to the cloud virtual instance which can grant access to other cloud resources in the account. The default containerd resolver is used by the cri-containerd plugin (which can be used by Kubernetes), the ctr development tool, and other client programs that have explicitly linked against it. This vulnerability has been fixed in containerd 1.2.14. containerd 1.3 and later are not affected. If you are using containerd 1.3 or later, you are not affected. If you are using cri-containerd in the 1.2 series or prior, you should ensure you only pull images from trusted sources. Other container runtimes built on top of containerd but not using the default resolver (such as Docker) are not affected. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,此 CVE 与容器相关。它涉及 containerd(一个容器运行时),并且问题出现在处理容器镜像的下载过程中,可能导致敏感信息泄露。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 此漏洞不会直接影响其他容器或宿主机的安全性。它的主要影响是泄露用于拉取镜像的认证凭据(如用户名和密码或云实例的访问密钥)。这些凭据可能被攻击者滥用以访问其他资源,但漏洞本身并不直接破坏容器隔离或宿主机的安全边界。 3. **结论**: 条件 1 满足,条件 2 不满足,因此返回分析结果而非 "N/A"。 cve: ./data/2020/15xxx/CVE-2020-15257.json containerd is an industry-standard container runtime and is available as a daemon for Linux and Windows. In containerd before versions 1.3.9 and 1.4.3, the containerd-shim API is improperly exposed to host network containers. Access controls for the shim’s API socket verified that the connecting process had an effective UID of 0, but did not otherwise restrict access to the abstract Unix domain socket. This would allow malicious containers running in the same network namespace as the shim, with an effective UID of 0 but otherwise reduced privileges, to cause new processes to be run with elevated privileges. This vulnerability has been fixed in containerd 1.3.9 and 1.4.3. Users should update to these versions as soon as they are released. It should be noted that containers started with an old version of containerd-shim should be stopped and restarted, as running containers will continue to be vulnerable even after an upgrade. If you are not providing the ability for untrusted users to start containers in the same network namespace as the shim (typically the "host" network namespace, for example with docker run --net=host or hostNetwork: true in a Kubernetes pod) and run with an effective UID of 0, you are not vulnerable to this issue. If you are running containers with a vulnerable configuration, you can deny access to all abstract sockets with AppArmor by adding a line similar to deny unix addr=@**, to your policy. It is best practice to run containers with a reduced set of privileges, with a non-zero UID, and with isolated namespaces. The containerd maintainers strongly advise against sharing namespaces with the host. Reducing the set of isolation mechanisms used for a container necessarily increases that container's privilege, regardless of what container runtime is used for running that container. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE与容器和隔离机制密切相关。具体来说,问题出在`containerd-shim` API的暴露方式上,它没有正确限制对抽象Unix域套接字的访问,从而允许恶意容器在同一网络命名空间(network namespace)中利用此漏洞。 2. **分析是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致恶意容器以提升的权限运行新进程。如果容器运行在与`containerd-shim`相同的网络命名空间中(例如使用`--net=host`选项),并且具有有效的UID为0,则可以利用此漏洞影响其他容器或宿主机。 3. **结论**: 由于条件1和条件2均满足,因此返回上述分析结果。 cve: ./data/2020/15xxx/CVE-2020-15360.json com.docker.vmnetd in Docker Desktop 2.3.0.3 allows privilege escalation because of a lack of client verification. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器相关。它涉及 Docker Desktop 的 `com.docker.vmnetd` 组件,这是一个与 Docker 容器运行环境密切相关的服务。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 是的,由于缺乏客户端验证,此漏洞可能导致特权 escalation。攻击者可能利用该漏洞突破容器的隔离机制,进而影响其他容器或宿主机的安全性。 因此,根据分析,该 CVE 满足条件 1 和条件 2。 cve: ./data/2020/15xxx/CVE-2020-15590.json A vulnerability in the Private Internet Access (PIA) VPN Client for Linux 1.5 through 2.3+ allows remote attackers to bypass an intended VPN kill switch mechanism and read sensitive information via intercepting network traffic. Since 1.5, PIA has supported a “split tunnel” OpenVPN bypass option. The PIA killswitch & associated iptables firewall is designed to protect you while using the Internet. When the kill switch is configured to block all inbound and outbound network traffic, privileged applications can continue sending & receiving network traffic if net.ipv4.ip_forward has been enabled in the system kernel parameters. For example, a Docker container running on a host with the VPN turned off, and the kill switch turned on, can continue using the internet, leaking the host IP (CWE 200). In PIA 2.4.0+, policy-based routing is enabled by default and is used to direct all forwarded packets to the VPN interface automatically. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 提及了 Docker 容器的行为。当系统的 `net.ipv4.ip_forward` 参数被启用时,即使 PIA 的 kill switch 配置为阻止所有入站和出站网络流量,Docker 容器仍然可以继续发送和接收网络流量。这表明该问题与容器的网络隔离机制相关。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 是的,该漏洞可能导致运行在宿主机上的 Docker 容器绕过 PIA 的 kill switch 机制,继续使用互联网,从而泄露宿主机的真实 IP 地址。这种行为会影响宿主机的安全性,并可能间接影响其他容器,因为宿主机的网络环境被暴露。 **结论:** 该 CVE 信息满足条件 1 和条件 2。 cve: ./data/2020/16xxx/CVE-2020-16120.json Overlayfs did not properly perform permission checking when copying up files in an overlayfs and could be exploited from within a user namespace, if, for example, unprivileged user namespaces were allowed. It was possible to have a file not readable by an unprivileged user to be copied to a mountpoint controlled by the user, like a removable device. This was introduced in kernel version 4.19 by commit d1d04ef ("ovl: stack file ops"). This was fixed in kernel version 5.8 by commits 56230d9 ("ovl: verify permissions in ovl_path_open()"), 48bd024 ("ovl: switch to mounter creds in readdir") and 05acefb ("ovl: check permission to open real file"). Additionally, commits 130fdbc ("ovl: pass correct flags for opening real directory") and 292f902 ("ovl: call secutiry hook in ovl_real_ioctl()") in kernel 5.8 might also be desired or necessary. These additional commits introduced a regression in overlay mounts within user namespaces which prevented access to files with ownership outside of the user namespace. This regression was mitigated by subsequent commit b6650da ("ovl: do not fail because of O_NOATIMEi") in kernel 5.11. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息与namespace相关。具体来说,问题出现在Overlayfs中权限检查的不当实现,当从一个用户namespace内进行文件复制操作时,可能导致未授权访问文件的情况。此外,问题描述中明确提到“unprivileged user namespaces”,这表明它与用户namespace的隔离机制直接相关。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能会影响容器的隔离性。如果容器使用了Overlayfs作为存储驱动(如Docker默认使用的overlay2),并且允许unprivileged user namespaces,攻击者可能利用此漏洞绕过权限限制,访问宿主机或其他容器中的文件。这种行为可能会破坏容器之间的隔离,甚至对宿主机造成威胁。 3. **结论**: 由于条件1和条件2均满足,因此返回上述分析结果,而不是"N/A"。 cve: ./data/2020/24xxx/CVE-2020-24263.json Portainer 1.24.1 and earlier is affected by an insecure permissions vulnerability that may lead to remote arbitrary code execution. A non-admin user is allowed to spawn new containers with critical capabilities such as SYS_MODULE, which can be used to take over the Docker host. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器技术密切相关。它描述了 Portainer(一个用于管理 Docker 容器的工具)中的漏洞,允许非管理员用户以关键权限(如 SYS_MODULE)创建新容器。 2. **是否会导致容器在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致非管理员用户利用关键权限(如 SYS_MODULE)创建具有高权限的容器,从而可能完全控制 Docker 宿主机。这将打破容器与宿主机之间的隔离,进而可能影响其他容器或宿主机的安全性。 因此,条件 1 和 2 均满足。 cve: ./data/2020/24xxx/CVE-2020-24264.json Portainer 1.24.1 and earlier is affected by incorrect access control that may lead to remote arbitrary code execution. The restriction checks for bind mounts are applied only on the client-side and not the server-side, which can lead to spawning a container with bind mount. Once such a container is spawned, it can be leveraged to break out of the container leading to complete Docker host machine takeover. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE与容器和隔离相关。它描述了Portainer在处理bind mounts时的访问控制问题,可能导致生成一个具有bind mount的容器。此外,还提到容器可能被利用来突破隔离,从而导致Docker宿主机被完全接管。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞会导致容器在运行时影响宿主机。通过利用此漏洞,攻击者可以创建一个具有不当权限的容器,并利用该容器突破隔离机制,最终实现对Docker宿主机的完全控制。这表明不仅会影响其他容器,还会直接威胁到宿主机的安全。 3. **结论**: 由于条件1和条件2均满足,因此返回上述分析结果。 cve: ./data/2020/25xxx/CVE-2020-25039.json Sylabs Singularity 3.2.0 through 3.6.2 has Insecure Permissions on temporary directories used in fakeroot or user namespace container execution. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 该CVE明确提到了Sylabs Singularity(一个容器运行时)以及用户命名空间(user namespace)和临时目录的权限问题。因此,它与容器和命名空间(namespace)相关。 2. **分析是否会导致容器在运行时影响其他容器或宿主机**: 由于该漏洞涉及不安全的临时目录权限,攻击者可能利用此漏洞在fakeroot或用户命名空间容器执行期间访问或修改其他文件,从而可能影响同一宿主机上的其他容器或宿主机本身的安全性。因此,该漏洞可能导致容器突破其隔离限制,进而影响其他容器或宿主机。 3. **结论**: 条件1和条件2均满足,因此返回分析结果而非"N/A"。 cve: ./data/2020/25xxx/CVE-2020-25201.json HashiCorp Consul Enterprise version 1.7.0 up to 1.8.4 includes a namespace replication bug which can be triggered to cause denial of service via infinite Raft writes.

Weave Net before version 2.8.0 has a vulnerability in which can allow an attacker to take over any host in the cluster. Weave Net is supplied with a manifest that runs pods on every node in a Kubernetes cluster, which are responsible for managing network connections for all other pods in the cluster. This requires a lot of power over the host, and the manifest sets `privileged: true`, which gives it that power. It also set `hostPID: true`, which gave it the ability to access all other processes on the host, and write anywhere in the root filesystem of the host. This setting was not necessary, and is being removed. You are only vulnerable if you have an additional vulnerability (e.g. a bug in Kubernetes) or misconfiguration that allows an attacker to run code inside the Weave Net pod, No such bug is known at the time of release, and there are no known instances of this being exploited. Weave Net 2.8.0 removes the hostPID setting and moves CNI plugin install to an init container. Users who do not update to 2.8.0 can edit the hostPID line in their existing DaemonSet manifest to say false instead of true, arrange some other way to install CNI plugins (e.g. Ansible) and remove those mounts from the DaemonSet manifest. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息与容器和隔离机制密切相关。Weave Net是一款用于连接Docker容器的虚拟网络工具,并且在Kubernetes集群中以特权模式(`privileged: true`)运行,同时还启用了`hostPID: true`,这直接影响了容器与宿主机之间的隔离性。 2. **分析是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器影响宿主机和其他容器。由于`hostPID: true`的设置,攻击者如果能够突破Weave Net Pod的安全边界,就可以访问宿主机上的所有进程,并对宿主机的根文件系统进行写操作。这种权限极大地削弱了容器与宿主机之间的隔离,使得攻击者可能进一步危害整个集群中的其他容器和节点。 **结论**:满足条件1和条件2,因此返回上述分析内容。 cve: ./data/2020/27xxx/CVE-2020-27352.json When generating the systemd service units for the docker snap (and other similar snaps), snapd does not specify Delegate=yes - as a result systemd will move processes from the containers created and managed by these snaps into the cgroup of the main daemon within the snap itself when reloading system units. This may grant additional privileges to a container within the snap that were not originally intended. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 该CVE明确提到`snapd`在生成systemd服务单元时未正确设置`Delegate=yes`,导致systemd将容器中的进程移动到snap主守护进程的cgroup中。这直接涉及到了cgroup和容器的隔离机制,因此与cgroup和容器隔离相关。 2. **分析是否会导致容器(如Docker)在运行时影响其他容器或宿主机**: 由于未设置`Delegate=yes`,容器中的进程被错误地移动到snap主守护进程的cgroup中,这可能导致容器获得额外的权限,这些权限原本是不属于容器的。这种行为可能破坏容器的隔离性,使容器能够影响宿主机或其他容器的资源分配和权限管理。 3. **结论**: 条件1和条件2均满足,因此返回以下分析结果: - 与namespace、cgroup、container或容器隔离相关:**是** - 可能影响其他容器或宿主机:**是** cve: ./data/2020/27xxx/CVE-2020-27534.json util/binfmt_misc/check.go in Builder in Docker Engine before 19.03.9 calls os.OpenFile with a potentially unsafe qemu-check temporary pathname, constructed with an empty first argument in an ioutil.TempDir call. analysis: ### 分析结果: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与容器技术相关。具体来说,问题出现在 Docker Engine 的 `util/binfmt_misc/check.go` 文件中,这是 Docker 引擎的一部分,负责处理二进制格式(binfmt_misc)以支持跨架构的容器运行(例如通过 QEMU)。因此,它直接涉及容器技术。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 是的,此漏洞可能导致安全风险。由于 `os.OpenFile` 使用了潜在不安全的临时文件路径名(由 `ioutil.TempDir` 构造且第一个参数为空),这可能会导致临时文件被其他进程篡改或覆盖,从而引发竞争条件或权限提升问题。这种问题可能允许攻击者利用该漏洞影响其他容器或宿主机的安全性。 ### 结论: - 条件 1 满足:与容器技术相关。 - 条件 2 满足:可能影响其他容器或宿主机。 因此,返回分析结果而非 "N/A"。 cve: ./data/2020/28xxx/CVE-2020-28348.json HashiCorp Nomad and Nomad Enterprise 0.9.0 up to 0.12.7 client Docker file sandbox feature may be subverted when not explicitly disabled or when using a volume mount type.

A guest may access xenstore paths via absolute paths containing a full pathname, or via a relative path, which implicitly includes /local/domain/$DOMID for their own domain id. Management tools must access paths in guests' namespaces, necessarily using absolute paths. oxenstored imposes a pathname limit that is applied solely to the relative or absolute path specified by the client. Therefore, a guest can create paths in its own namespace which are too long for management tools to access. Depending on the toolstack in use, a malicious guest administrator might cause some management tools and debugging operations to fail. For example, a guest administrator can cause "xenstore-ls -r" to fail. However, a guest administrator cannot prevent the host administrator from tearing down the domain. All systems using oxenstored are vulnerable. Building and using oxenstored is the default in the upstream Xen distribution, if the Ocaml compiler is available. Systems using C xenstored are not vulnerable. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关:** 该CVE信息涉及Xen虚拟化技术中的`xenstore`路径访问问题。`xenstore`是一个用于在Xen环境中进行域间通信的小型键值存储系统,主要用于管理工具和客户机之间的交互。虽然这不是直接关于Linux namespace或cgroup的技术,但它涉及到虚拟化环境中的隔离问题,特别是客户机(guest)与管理工具之间的交互。因此,可以认为它与隔离机制相关。 2. **分析是否会导致容器(如Docker等)在运行时影响其他容器或宿主机:** 该漏洞主要影响Xen虚拟化环境,而不是容器技术(如Docker)。虽然Xen和容器都属于虚拟化技术,但它们的实现方式不同。Xen是基于硬件虚拟化的完全虚拟化技术,而Docker是基于Linux namespace和cgroup的轻量级容器技术。此漏洞不会直接影响Docker或其他容器技术的运行时行为,也不会导致容器影响其他容器或宿主机。 3. **结论:** 根据以上分析,该CVE信息与隔离机制相关,但不适用于容器技术(如Docker)。因此,返回结果为: **N/A** cve: ./data/2020/29xxx/CVE-2020-29564.json The official Consul Docker images 0.7.1 through 1.4.2 contain a blank password for a root user.

The impact is limited to host services that create UNIX sockets that WebKit mounts inside its sandbox, and the sandboxed process remains otherwise confined. NOTE: this is similar to CVE-2021-41133. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,这个CVE与namespace和隔离相关。描述中提到“sandbox bypass”以及“filesystem namespace”,表明问题涉及文件系统命名空间的隔离机制。具体来说,漏洞允许沙盒内的进程通过滥用VFS系统调用来操控其文件系统命名空间,从而欺骗宿主机上的进程,使其认为该沙盒内进程未被隔离。 2. **是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 根据描述,影响是有限的。漏洞仅影响那些创建UNIX套接字并将其挂载到WebKit沙盒内的宿主机服务。沙盒内的进程仍然保持其他方面的隔离。因此,虽然此漏洞可能导致一定程度的隔离失效,但并不会直接导致容器运行时影响其他容器或宿主机(除非宿主机上有特定的服务配置,且这些服务依赖于受影响的沙盒机制)。 **结论**:满足条件1,部分满足条件2(影响有限)。 cve: ./data/2021/43xxx/CVE-2021-43784.json runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc, netlink is used internally as a serialization system for specifying the relevant container configuration to the `C` portion of the code (responsible for the based namespace setup of containers). In all versions of runc prior to 1.0.3, the encoder did not handle the possibility of an integer overflow in the 16-bit length field for the byte array attribute type, meaning that a large enough malicious byte array attribute could result in the length overflowing and the attribute contents being parsed as netlink messages for container configuration. This vulnerability requires the attacker to have some control over the configuration of the container and would allow the attacker to bypass the namespace restrictions of the container by simply adding their own netlink payload which disables all namespaces. The main users impacted are those who allow untrusted images with untrusted configurations to run on their machines (such as with shared cloud infrastructure). runc version 1.0.3 contains a fix for this bug. As a workaround, one may try disallowing untrusted namespace paths from your container. It should be noted that untrusted namespace paths would allow the attacker to disable namespace protections entirely even in the absence of this bug. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,这个 CVE 与 namespace 和容器隔离直接相关。漏洞描述中明确提到,攻击者可以通过构造恶意的字节数组属性,导致 netlink 消息被错误解析,从而绕过容器的 namespace 限制。Namespace 是 Linux 容器(如 Docker)实现隔离的核心机制之一,因此该漏洞直接影响了容器的隔离性。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能会导致容器突破隔离,影响宿主机或其他容器的安全性。具体来说,攻击者可以通过此漏洞禁用所有 namespaces,从而使容器能够访问宿主机的资源,甚至可能进一步危害宿主机上的其他容器或系统本身。这违反了容器设计中的隔离原则。 **结论**:满足条件 1 和条件 2,无需返回 "N/A"。 cve: ./data/2021/44xxx/CVE-2021-44731.json A race condition existed in the snapd 2.54.2 snap-confine binary when preparing a private mount namespace for a snap. This could allow a local attacker to gain root privileges by bind-mounting their own contents inside the snap's private mount namespace and causing snap-confine to execute arbitrary code and hence gain privilege escalation. Fixed in snapd versions 2.54.3+18.04, 2.54.3+20.04 and 2.54.3+21.10.1 analysis: 1. 该 CVE 信息与 namespace 相关,因为它提到了 "private mount namespace" 的准备过程中存在竞争条件。 2. 该 CVE 可能会导致容器运行时受到影响,因为攻击者可以通过 bind-mount 的方式注入自己的内容到 snap 的私有挂载命名空间中,并导致 snap-confine 执行任意代码。这可能会进一步影响宿主机或其他容器的隔离性,尤其是在共享宿主机的情况下。 3. 因此,这个 CVE 满足条件 1 和 2。 cve: ./data/2021/46xxx/CVE-2021-46283.json nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own namespace. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关** 该 CVE 描述中提到 `nft_set_elem_expr_alloc` 的初始化缺失问题,导致本地用户可以在其自己的命名空间(namespace)中设置 netfilter 表达式。由于涉及到命名空间(namespace),这与 Linux 容器的隔离机制有一定关联,因为命名空间是容器隔离的核心技术之一。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机** 虽然该漏洞允许本地用户在其自己的命名空间中触发问题,但描述中并未明确指出此漏洞能够突破命名空间的限制,从而影响其他容器或宿主机。因此,从现有信息来看,该漏洞似乎仅限于在用户自己的命名空间内造成拒绝服务(DoS),而不会直接影响其他容器或宿主机。 3. **结论** 条件 1 满足(与命名空间相关),条件 2 不满足(不会影响其他容器或宿主机)。 cve: ./data/2021/46xxx/CVE-2021-46912.json In the Linux kernel, the following vulnerability has been resolved: net: Make tcp_allowed_congestion_control readonly in non-init netns Currently, tcp_allowed_congestion_control is global and writable; writing to it in any net namespace will leak into all other net namespaces. tcp_available_congestion_control and tcp_allowed_congestion_control are the only sysctls in ipv4_net_table (the per-netns sysctl table) with a NULL data pointer; their handlers (proc_tcp_available_congestion_control and proc_allowed_congestion_control) have no other way of referencing a struct net. Thus, they operate globally. Because ipv4_net_table does not use designated initializers, there is no easy way to fix up this one "bad" table entry. However, the data pointer updating logic shouldn't be applied to NULL pointers anyway, so we instead force these entries to be read-only. These sysctls used to exist in ipv4_table (init-net only), but they were moved to the per-net ipv4_net_table, presumably without realizing that tcp_allowed_congestion_control was writable and thus introduced a leak. Because the intent of that commit was only to know (i.e. read) "which congestion algorithms are available or allowed", this read-only solution should be sufficient. The logic added in recent commit 31c4d2f160eb: ("net: Ensure net namespace isolation of sysctls") does not and cannot check for NULL data pointers, because other table entries (e.g. /proc/sys/net/netfilter/nf_log/) have .data=NULL but use other methods (.extra2) to access the struct net. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 描述了 `tcp_allowed_congestion_control` 在非初始化网络命名空间(non-init netns)中是可写的,这会导致一个网络命名空间的更改泄露到其他网络命名空间。因此,此漏洞直接涉及 Linux 的网络命名空间(network namespace),这是容器隔离机制的一部分。容器技术(如 Docker)通常依赖于命名空间来实现资源隔离,因此该问题与容器隔离密切相关。 2. **分析是否会导致容器在运行时影响其他容器或宿主机**: 由于 `tcp_allowed_congestion_control` 是全局可写的,更改在一个容器的网络命名空间中的值可能会泄露到其他容器或宿主机的网络命名空间。这种行为破坏了容器之间的隔离性,可能导致意外的行为或安全风险。因此,此漏洞会影响容器的隔离性,并可能间接影响其他容器或宿主机。 3. **结论**: 条件 1 和条件 2 均满足,因此需要返回分析结果而不是 "N/A"。 **最终分析结果**: - 该 CVE 与网络命名空间相关,直接影响容器的隔离性。 - 容器运行时的配置更改可能泄露到其他容器或宿主机,破坏隔离性。 cve: ./data/2021/46xxx/CVE-2021-46936.json In the Linux kernel, the following vulnerability has been resolved: net: fix use-after-free in tw_timer_handler A real world panic issue was found as follow in Linux 5.4.

The ipv4_mib_exit_net is called before tcp_sk_exit_batch when a net namespace is destroyed since tcp_sk_ops is registered befrore ipv4_mib_ops, which means tcp_sk_ops is in the front of ipv4_mib_ops in the list of pernet_list. There will be a use-after-free on net->mib.net_statistics in tw_timer_handler after ipv4_mib_exit_net if there are some inflight time-wait timers. This bug is not introduced by commit f2bf415cfed7 ("mib: add net to NET_ADD_STATS_BH") since the net_statistics is a global variable instead of dynamic allocation and freeing. Actually, commit 61a7e26028b9 ("mib: put net statistics on struct net") introduces the bug since it put net statistics on struct net and free it when net namespace is destroyed. Moving init_ipv4_mibs() to the front of tcp_init() to fix this bug and replace pr_crit() with panic() since continuing is meaningless when init_ipv4_mibs() fails. [1] https://groups.google.com/g/syzkaller/c/p1tn-_Kc6l4/m/smuL_FMAAgAJ?pli=1 analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该漏洞涉及网络命名空间(net namespace)。问题出现在销毁网络命名空间时,`ipv4_mib_exit_net` 被调用在 `tcp_sk_exit_batch` 之前,导致了 `tw_timer_handler` 中的 use-after-free 问题。网络命名空间是 Linux 容器(如 Docker)实现网络隔离的核心机制之一,因此该漏洞与命名空间和隔离相关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机** 是的,该漏洞可能导致容器在运行时影响宿主机或其他容器。由于网络命名空间是容器隔离的重要组成部分,如果一个容器的网络命名空间被销毁时触发了该漏洞,可能会导致宿主机内核崩溃(panic),从而影响整个系统以及运行在该宿主机上的所有容器。 3. **结论** 根据以上分析,条件 1 和 2 均满足。 cve: ./data/2021/47xxx/CVE-2021-47010.json In the Linux kernel, the following vulnerability has been resolved: net: Only allow init netns to set default tcp cong to a restricted algo tcp_set_default_congestion_control() is netns-safe in that it writes to &net->ipv4.tcp_congestion_control, but it also sets ca->flags |= TCP_CONG_NON_RESTRICTED which is not namespaced. This has the unintended side-effect of changing the global net.ipv4.tcp_allowed_congestion_control sysctl, despite the fact that it is read-only: 97684f0970f6 ("net: Make tcp_allowed_congestion_control readonly in non-init netns") Resolve this netns "leak" by only allowing the init netns to set the default algorithm to one that is restricted. This restriction could be removed if tcp_allowed_congestion_control were namespace-ified in the future. This bug was uncovered with https://github.com/JonathonReinhart/linux-netns-sysctl-verify analysis: 1. **是否与 namespace、cgroup、container 或容器、隔离相关**: 是的,这个 CVE 信息与 namespace 相关。具体来说,它涉及网络命名空间(netns)的安全问题。`tcp_set_default_congestion_control()` 函数在设置默认 TCP 拥塞控制算法时,虽然针对特定命名空间进行了操作,但意外地修改了全局的 `net.ipv4.tcp_allowed_congestion_control` 系统参数。这表明该漏洞与 Linux 命名空间的隔离性有关。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 是的,此漏洞可能会导致容器影响宿主机或其他容器。由于问题在于网络命名空间的隔离性被破坏,非初始化命名空间(non-init netns)可以间接修改全局的 TCP 拥塞控制设置,这可能会影响宿主机上的网络行为以及其他使用相同内核的容器。 3. **结论**: 条件 1 和条件 2 都满足,因此需要返回分析结果,而不是 "N/A"。 cve: ./data/2021/47xxx/CVE-2021-47011.json In the Linux kernel, the following vulnerability has been resolved: mm: memcontrol: slab: fix obtain a reference to a freeing memcg Patch series "Use obj_cgroup APIs to charge kmem pages", v5. Since Roman's series "The new cgroup slab memory controller" applied. All slab objects are charged with the new APIs of obj_cgroup. The new APIs introduce a struct obj_cgroup to charge slab objects. It prevents long-living objects from pinning the original memory cgroup in the memory. But there are still some corner objects (e.g. allocations larger than order-1 page on SLUB) which are not charged with the new APIs. Those objects (include the pages which are allocated from buddy allocator directly) are charged as kmem pages which still hold a reference to the memory cgroup. E.g. We know that the kernel stack is charged as kmem pages because the size of the kernel stack can be greater than 2 pages (e.g. 16KB on x86_64 or arm64). If we create a thread (suppose the thread stack is charged to memory cgroup A) and then move it from memory cgroup A to memory cgroup B. Because the kernel stack of the thread hold a reference to the memory cgroup A. The thread can pin the memory cgroup A in the memory even if we remove the cgroup A. If we want to see this scenario by using the following script. We can see that the system has added 500 dying cgroups (This is not a real world issue, just a script to show that the large kmallocs are charged as kmem pages which can pin the memory cgroup in the memory). #!/bin/bash cat /proc/cgroups | grep memory cd /sys/fs/cgroup/memory echo 1 > memory.move_charge_at_immigrate for i in range{1..500} do mkdir kmem_test echo $$ > kmem_test/cgroup.procs sleep 3600 & echo $$ > cgroup.procs echo `cat kmem_test/cgroup.procs` > cgroup.procs rmdir kmem_test done cat /proc/cgroups | grep memory This patchset aims to make those kmem pages to drop the reference to memory cgroup by using the APIs of obj_cgroup. Finally, we can see that the number of the dying cgroups will not increase if we run the above test script. This patch (of 7): The rcu_read_lock/unlock only can guarantee that the memcg will not be freed, but it cannot guarantee the success of css_get (which is in the refill_stock when cached memcg changed) to memcg. rcu_read_lock() memcg = obj_cgroup_memcg(old) __memcg_kmem_uncharge(memcg) refill_stock(memcg) if (stock->cached != memcg) // css_get can change the ref counter from 0 back to 1. css_get(&memcg->css) rcu_read_unlock() This fix is very like the commit: eefbfa7fd678 ("mm: memcg/slab: fix use after free in obj_cgroup_charge") Fix this by holding a reference to the memcg which is passed to the __memcg_kmem_uncharge() before calling __memcg_kmem_uncharge(). analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,这个 CVE 信息与 cgroup 相关。它涉及到 Linux 内核中的内存控制组 (memory cgroup) 和 slab 分配器的实现。具体来说,问题出现在对内存控制组的引用计数管理上,可能导致长期存在的对象(如内核栈)在内存控制组被移除后仍然持有对该控制组的引用,从而阻止其被正确释放。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 可能会。由于该漏洞涉及内存控制组的管理,而内存控制组是容器隔离机制的重要组成部分之一(用于限制和隔离容器的资源使用),因此如果一个容器的内存使用行为触发了此漏洞,可能会导致内存控制组的不正确释放或引用计数问题。这可能间接影响到其他容器或宿主机的资源管理,尤其是在多租户环境下,可能会导致资源泄漏或隔离性受损。 3. **结论**: 条件 1 和条件 2 都满足,因此返回分析结果而不是 "N/A"。 cve: ./data/2021/47xxx/CVE-2021-47379.json In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: fix UAF by grabbing blkcg lock before destroying blkg pd KASAN reports a use-after-free report when doing fuzz test: [693354.104835] ================================================================== [693354.105094] BUG: KASAN: use-after-free in bfq_io_set_weight_legacy+0xd3/0x160 [693354.105336] Read of size 4 at addr ffff888be0a35664 by task sh/1453338 [693354.105607] CPU: 41 PID: 1453338 Comm: sh Kdump: loaded Not tainted 4.18.0-147 [693354.105610] Hardware name: Huawei 2288H V5/BC11SPSCB0, BIOS 0.81 07/02/2018 [693354.105612] Call Trace: [693354.105621] dump_stack+0xf1/0x19b [693354.105626] ?

Specifically, the issue involves a Use-After-Free (UAF) vulnerability in the block I/O control group (`blk-cgroup`) subsystem of the Linux kernel. Control groups are a fundamental component of containerization technologies like Docker, as they are used to limit and isolate resource usage (CPU, memory, block I/O, etc.) for groups of processes. 2. **Does this CVE affect other containers or the host when running containers like Docker?** - Potentially yes. The `blk-cgroup` subsystem is responsible for managing and enforcing block I/O resource limits for processes within a cgroup. If an attacker can exploit this UAF vulnerability, it could lead to arbitrary code execution or a denial of service (DoS) condition. This could allow a malicious container to escape its resource restrictions, potentially affecting other containers or even the host system if the vulnerability is successfully exploited. 3. **Conclusion:** - Since both conditions 1 and 2 are satisfied, this CVE is relevant to container isolation and could impact the security of containerized environments. **Final Answer:** - Related to namespace/cgroup/container/isolation: **Yes**. - Can affect other containers or the host: **Potentially yes**. cve: ./data/2021/47xxx/CVE-2021-47579.json In the Linux kernel, the following vulnerability has been resolved: ovl: fix warning in ovl_create_real() Syzbot triggered the following warning in ovl_workdir_create() -> ovl_create_real(): if (!err && WARN_ON(!newdentry->d_inode)) { The reason is that the cgroup2 filesystem returns from mkdir without instantiating the new dentry. Weird filesystems such as this will be rejected by overlayfs at a later stage during setup, but to prevent such a warning, call ovl_mkdir_real() directly from ovl_workdir_create() and reject this case early. analysis: 1. **分析是否与 namespace、cgroup、container 或容器、隔离相关** 该 CVE 涉及到 `cgroup2` 文件系统和 `overlayfs`,而 `cgroup2` 是 Linux 控制组(cgroup)的第二代实现,用于资源限制、优先级、会计等。此外,`overlayfs` 是一种常用于容器技术(如 Docker)的文件系统,用于提供分层文件系统支持。因此,这个 CVE 与 cgroup 和容器技术相关。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机** 该漏洞涉及 `ovl_create_real()` 函数中的警告处理问题,当 `cgroup2` 文件系统返回未实例化的新 dentry 时,可能会触发警告。虽然此问题已被修复以避免警告,但它可能暴露了 `overlayfs` 在处理特殊文件系统时的潜在不稳定性。如果 `overlayfs` 的行为受到影响,理论上可能导致容器的文件系统操作异常,进而间接影响其他容器或宿主机的稳定性。然而,从描述来看,此漏洞并未直接导致安全边界突破(如逃逸到宿主机),而是更偏向于功能性或稳定性问题。 3. **结论** 根据上述分析,该 CVE 与 cgroup 和容器技术相关,并可能对容器的稳定性产生一定影响,但没有明确证据表明它会导致容器逃逸或直接影响其他容器或宿主机的安全性。因此,满足条件 1 和部分条件 2。 cve: ./data/2021/47xxx/CVE-2021-47584.json In the Linux kernel, the following vulnerability has been resolved: iocost: Fix divide-by-zero on donation from low hweight cgroup The donation calculation logic assumes that the donor has non-zero after-donation hweight, so the lowest active hweight a donating cgroup can have is 2 so that it can donate 1 while keeping the other 1 for itself. Earlier, we only donated from cgroups with sizable surpluses so this condition was always true. However, with the precise donation algorithm implemented, f1de2439ec43 ("blk-iocost: revamp donation amount determination") made the donation amount calculation exact enabling even low hweight cgroups to donate.

Excluding these extreme low hweight donations shouldn't affect work conservation in any meaningful way. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该 CVE 信息与 cgroup 相关。具体来说,问题出现在 Linux 内核的 iocost 子系统中,涉及 cgroup 的捐赠逻辑(donation logic)。cgroup 是 Linux 中用于实现资源限制和隔离的重要机制,因此该问题与 cgroup 和隔离密切相关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机** 从描述来看,这个问题主要是一个除以零错误(divide-by-zero),它可能导致内核崩溃(oops)。如果此漏洞被触发,可能会影响整个系统的稳定性,包括宿主机和其他运行在宿主机上的容器。因此,该漏洞可能会导致容器运行时影响其他容器或宿主机。 3. **结论** 根据以上分析,条件 1 和 2 均满足,因此返回以下分析结果: - 与 cgroup 和隔离相关。 - 可能会导致容器影响其他容器或宿主机。 cve: ./data/2021/4xxx/CVE-2021-4154.json A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 信息明确提到 `cgroup1_parse_param` 函数,这是 Linux 内核中 cgroup v1 的一部分。Cgroup(Control Group)是用于限制、控制和隔离进程组资源使用的重要机制,广泛应用于容器技术(如 Docker)中以实现资源隔离。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器突破(container breakout)。具体来说,攻击者可以通过利用 `fsconfig` 系统调用参数中的 use-after-free 漏洞,提升权限并逃逸出容器环境,从而影响其他容器或宿主机的安全性。此外,漏洞还可能引发拒绝服务(Denial of Service, DoS),进一步威胁系统稳定性。 **结论**:该 CVE 信息满足条件 1 和 2。 cve: ./data/2021/4xxx/CVE-2021-4197.json An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 明确提到 Linux 内核的 control groups (cgroups) 和 namespaces 子系统存在漏洞。cgroups 是容器技术(如 Docker)中用于资源限制和隔离的重要组成部分,因此该漏洞与 cgroups 和隔离机制直接相关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能会影响容器的安全性。由于 cgroups 是容器资源隔离的核心机制之一,如果攻击者利用此漏洞,可能会突破容器的隔离边界,影响其他容器或宿主机。具体来说,漏洞允许本地用户通过未授权的写操作导致系统崩溃或权限提升,这可能被恶意容器利用来影响宿主机或其他容器的稳定性或安全性。 **结论**:满足条件 1 和 2。 cve: ./data/2022/0xxx/CVE-2022-0070.json Incomplete fix for CVE-2021-3100. The Apache Log4j hotpatch package starting with log4j-cve-2021-44228-hotpatch-1.1-16 will now explicitly mimic the Linux capabilities and cgroups of the target Java process that the hotpatch is applied to. analysis: 1. **分析是否与 namespace、cgroup、container 或容器、隔离相关** 该 CVE 描述提到 Log4j 的 hotpatch 包会显式模仿目标 Java 进程的 Linux capabilities 和 cgroups。因此,它确实与 cgroups 相关,但没有直接提及 namespace、容器或隔离机制。 2. **分析是否会影响其他容器或宿主机** 由于该漏洞涉及模仿目标 Java 进程的 cgroups,如果目标进程运行在容器中,而 hotpatch 的行为不当(例如权限提升或资源分配错误),可能会间接影响容器的隔离性。然而,根据描述,hotpatch 的设计目的是模仿目标进程的配置,理论上不会主动破坏容器隔离或影响宿主机。因此,从描述来看,直接影响其他容器或宿主机的风险较低。 3. **结论** 条件 1 满足(与 cgroups 相关),条件 2 不完全满足(无明确证据表明会影响其他容器或宿主机)。因此,返回以下分析结果: - 与 cgroups 相关,可能间接影响容器隔离性,但无明确证据表明会导致容器逃逸或影响宿主机。 cve: ./data/2022/0xxx/CVE-2022-0185.json A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system. analysis: 1. 该 CVE 信息与 namespace 相关。具体来说,问题涉及到“unprivileged user namespaces”功能。如果系统启用了非特权用户命名空间(unprivileged user namespaces),则攻击者可以利用此漏洞。此外,问题还涉及文件系统上下文(Filesystem Context)和参数解析逻辑。 2. 该 CVE 可能会影响容器的隔离性。在容器环境中(如 Docker),如果容器启用了 unprivileged user namespaces 或具有 namespaced CAP_SYS_ADMIN 权限,则攻击者可能利用此漏洞从容器内部进行权限提升,进而影响宿主机或其他容器的安全性。 因此,根据分析要求,条件 1 和 2 均满足。 cve: ./data/2022/0xxx/CVE-2022-0324.json There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash. Dhcp6relay is a critical process and could cause dhcp relay docker to shutdown. Discovered by Eugene Lim of GovTech Singapore. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 提及了 `dhcp relay docker` 会受到影响。这表明问题与 Docker 容器相关,并且可能影响到容器内的关键进程 (`dhcp6relay`)。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 根据描述,漏洞会导致 `dhcp6relay` 崩溃,进而导致 `dhcp relay docker` 关闭。这种影响似乎是局限于特定容器(`dhcp relay docker`)内部的,没有明确提到会对其他容器或宿主机造成直接影响。然而,如果 `dhcp relay docker` 是一个共享网络配置或提供关键服务的容器,它的崩溃可能会间接影响依赖它的其他容器或宿主机的服务稳定性。 3. **结论:** 条件 1 满足(与容器相关),条件 2 部分满足(虽然直接影响有限,但可能存在间接影响)。因此,返回分析结果而非 "N/A"。 cve: ./data/2022/0xxx/CVE-2022-0492.json A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly. analysis: 1. 该 CVE 信息与 namespace、cgroup、container 和隔离相关。描述中明确提到 cgroups v1 的 `release_agent` 功能,并且提到了可以绕过 namespace 的隔离。 2. 该 CVE 可能会导致容器(例如 Docker)在运行时影响其他容器或宿主机。通过利用 cgroups v1 的 `release_agent` 功能,攻击者可能能够突破容器的隔离机制,从而对宿主机或其他容器造成潜在威胁。 因此,条件 1 和 2 均满足。 cve: ./data/2022/0xxx/CVE-2022-0532.json An incorrect sysctls validation vulnerability was found in CRI-O 1.18 and earlier. The sysctls from the list of "safe" sysctls specified for the cluster will be applied to the host if an attacker is able to create a pod with a hostIPC and hostNetwork kernel namespace. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息与namespace和容器隔离相关。描述中提到攻击者可以通过创建一个具有`hostIPC`和`hostNetwork`内核命名空间的Pod,导致指定的`sysctls`被应用到主机上。这表明问题涉及容器的命名空间配置以及其与宿主机的交互。 2. **是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器影响宿主机。由于攻击者可以利用`hostIPC`和`hostNetwork`命名空间将`sysctls`应用到宿主机,这可能会破坏宿主机的安全性或稳定性,进而可能影响在同一宿主机上运行的其他容器。 3. **结论**: 该CVE满足条件1和条件2,因此不会返回"N/A"。 cve: ./data/2022/1xxx/CVE-2022-1055.json A use-after-free exists in the Linux Kernel in tc_new_tfilter that could allow a local attacker to gain privilege escalation. The exploit requires unprivileged user namespaces. We recommend upgrading past commit 04c2a47ffb13c29778e2a14e414ad4cb5a5db4b5 analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞提到了“unprivileged user namespaces”,这表明它与用户命名空间(user namespace)有关。用户命名空间是Linux内核中用于隔离用户和组ID的一种机制,广泛应用于容器技术(如Docker)中以提供隔离性。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致特权提升(privilege escalation)。由于其利用需要“unprivileged user namespaces”,而这些命名空间通常在容器环境中被启用,因此攻击者可能通过此漏洞从容器内部逃逸,影响其他容器或宿主机的安全性。 **结论**:满足条件1和条件2。 cve: ./data/2022/1xxx/CVE-2022-1833.json A flaw was found in AMQ Broker Operator 7.9.4 installed via UI using OperatorHub where a low-privilege user that has access to the namespace where the AMQ Operator is deployed has access to clusterwide edit rights by checking the secrets. The service account used for building the Operator gives more permission than expected and an attacker could benefit from it. This requires at least an already compromised low-privilege account or insider attack. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 和容器隔离相关。问题发生在 AMQ Broker Operator 的部署中,低权限用户可以通过访问特定 namespace 中的秘密(secrets)获得集群范围的编辑权限。这表明在 namespace 层面的权限控制存在漏洞,可能导致隔离机制被破坏。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 可能会。由于服务账户的权限超出预期,攻击者可能利用此漏洞获取集群范围的编辑权限,进而影响其他容器或宿主机。例如,攻击者可以修改其他容器的配置、访问敏感数据,甚至对宿主机进行未授权的操作。 **结论:** 满足条件 1 和 2,因此返回上述分析结果。 cve: ./data/2022/23xxx/CVE-2022-23774.json Docker Desktop before 4.4.4 on Windows allows attackers to move arbitrary files. analysis: 1. 该 CVE 信息与 namespace、cgroup、container 或者容器相关。 原因:描述中明确提到 Docker Desktop,并且涉及文件移动操作,这可能与容器的文件系统隔离机制有关。 2. 该 CVE 可能会导致容器在运行时影响其他容器或宿主机。 原因:描述中提到“允许攻击者移动任意文件”,这意味着攻击者可能利用此漏洞突破容器的隔离限制,对宿主机或其他容器的文件系统进行未授权访问或修改。 **结论:满足条件 1 和 2。** cve: ./data/2022/24xxx/CVE-2022-24122.json kernel/ucount.c in the Linux kernel 5.14 through 5.16.4, when unprivileged user namespaces are enabled, allows a use-after-free and privilege escalation because a ucounts object can outlive its namespace. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与 namespace 相关。描述中明确提到“unprivileged user namespaces”,即非特权用户命名空间,这是 Linux 容器(如 Docker)实现隔离的重要机制之一。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 是的,可能会导致影响。由于存在 use-after-free 和权限提升漏洞,攻击者可以利用此漏洞突破容器的隔离机制,进而可能影响同一宿主机上的其他容器,甚至完全控制宿主机。 **结论:** 满足条件 1 和条件 2。 cve: ./data/2022/24xxx/CVE-2022-24769.json Moby is an open-source project created by Docker to enable and accelerate software containerization. A bug was found in Moby (Docker Engine) prior to version 20.10.14 where containers were incorrectly started with non-empty inheritable Linux process capabilities, creating an atypical Linux environment and enabling programs with inheritable file capabilities to elevate those capabilities to the permitted set during `execve(2)`. Normally, when executable programs have specified permitted file capabilities, otherwise unprivileged users and processes can execute those programs and gain the specified file capabilities up to the bounding set. Due to this bug, containers which included executable programs with inheritable file capabilities allowed otherwise unprivileged users and processes to additionally gain these inheritable file capabilities up to the container's bounding set. Containers which use Linux users and groups to perform privilege separation inside the container are most directly impacted. This bug did not affect the container security sandbox as the inheritable set never contained more capabilities than were included in the container's bounding set. This bug has been fixed in Moby (Docker Engine) 20.10.14. Running containers should be stopped, deleted, and recreated for the inheritable capabilities to be reset. This fix changes Moby (Docker Engine) behavior such that containers are started with a more typical Linux environment. As a workaround, the entry point of a container can be modified to use a utility like `capsh(1)` to drop inheritable capabilities prior to the primary process starting. analysis: ### 分析结果: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 信息明确提到 Moby(Docker Engine)中的一个漏洞,涉及容器的启动行为以及 Linux 进程能力(capabilities)的设置。这直接影响了容器内的进程权限管理,因此与容器和隔离机制密切相关。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 该漏洞允许容器内的非特权用户或进程通过 inheritable file capabilities 提升权限,但这仅限于容器的 bounding set 范围内。由于 inheritable set 不会包含超出容器 bounding set 的能力,因此该漏洞不会直接突破容器的安全沙箱,也不会直接影响其他容器或宿主机的安全性。然而,它可能削弱容器内部基于用户和组的权限分离机制,从而间接增加攻击面。 ### 结论: - 满足条件 1 和 2 的部分分析要求。 - 该漏洞虽然不会直接影响宿主机或其他容器,但会对容器内部的权限隔离产生负面影响,需要关注并修复。 cve: ./data/2022/24xxx/CVE-2022-24778.json The imgcrypt library provides API exensions for containerd to support encrypted container images and implements the ctd-decoder command line tool for use by containerd to decrypt encrypted container images. The imgcrypt function `CheckAuthorization` is supposed to check whether the current used is authorized to access an encrypted image and prevent the user from running an image that another user previously decrypted on the same system. In versions prior to 1.1.4, a failure occurs when an image with a ManifestList is used and the architecture of the local host is not the first one in the ManifestList. Only the first architecture in the list was tested, which may not have its layers available locally since it could not be run on the host architecture. Therefore, the verdict on unavailable layers was that the image could be run anticipating that image run failure would occur later due to the layers not being available. However, this verdict to allow the image to run enabled other architectures in the ManifestList to run an image without providing keys if that image had previously been decrypted. A patch has been applied to imgcrypt 1.1.4. Workarounds may include usage of different namespaces for each remote user. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与容器和隔离相关。`imgcrypt` 是为 `containerd` 提供支持加密容器镜像的 API 扩展,并且涉及到 `ctd-decoder` 命令行工具用于解密加密的容器镜像。此外,描述中提到可以通过使用不同的命名空间(namespaces)作为解决方法之一,这表明该问题与容器隔离机制有关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 是的,该漏洞可能导致容器运行时的安全风险。由于 `CheckAuthorization` 函数的实现问题,如果某个用户之前在系统上解密了一个镜像,其他用户可能无需提供正确的密钥即可运行该镜像中的其他架构。这种行为破坏了容器之间的隔离性,可能会导致未经授权的访问或其他安全问题,进而影响其他容器或宿主机的安全性。 3. **结论:** 该 CVE 满足条件 1 和条件 2,因此需要返回上述分析内容,而不是 "N/A"。 cve: ./data/2022/25xxx/CVE-2022-25365.json Docker Desktop before 4.5.1 on Windows allows attackers to move arbitrary files. NOTE: this issue exists because of an incomplete fix for CVE-2022-23774. analysis: 1. 该 CVE 信息与 namespace、cgroup、container 或容器相关。原因是它明确提到了 Docker Desktop 在 Windows 上的问题,Docker 是一个容器化平台,因此该问题与容器技术直接相关。 2. 该 CVE 可能会导致容器在运行时影响其他容器或宿主机。根据描述,攻击者可以移动任意文件,这种行为可能突破容器的隔离性,进而对宿主机或其他容器造成潜在影响。 总结:条件 1 和 2 均满足。 cve: ./data/2022/26xxx/CVE-2022-26659.json Docker Desktop installer on Windows in versions before 4.6.0 allows an attacker to overwrite any administrator writable files by creating a symlink in place of where the installer writes its log file.

By crafting a bogus Firejail container that is accepted by the Firejail setuid-root program as a join target, a local attacker can enter an environment in which the Linux user namespace is still the initial user namespace, the NO_NEW_PRIVS prctl is not activated, and the entered mount namespace is under the attacker's control. In this way, the filesystem layout can be adjusted to gain root privileges through execution of available setuid-root binaries such as su or sudo. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 和容器隔离相关。问题出现在 Firejail 的 `join.c` 文件中,Firejail 是一个用于沙盒化应用程序的工具,利用 Linux namespaces 提供隔离环境。漏洞描述中明确提到用户命名空间(user namespace)和挂载命名空间(mount namespace),并且涉及通过调整文件系统布局来突破隔离。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 虽然此漏洞是针对 Firejail 的,但其核心问题在于对命名空间的不当处理。如果类似的漏洞存在于其他容器运行时(如 Docker 的运行时),也可能导致攻击者突破容器隔离,进入初始用户命名空间,并可能进一步影响宿主机或其他容器。因此,从原理上讲,这种类型的漏洞有潜在风险影响容器运行时的安全性。 **结论:** 满足条件 1 和 2,因此返回分析结果而非 "N/A"。 cve: ./data/2022/31xxx/CVE-2022-31647.json Docker Desktop before 4.6.0 on Windows allows attackers to delete any file through the hyperv/destroy dockerBackendV2 API via a symlink in the DataFolder parameter, a different vulnerability than CVE-2022-26659. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与容器技术相关。它涉及 Docker Desktop 在 Windows 上的一个 API (`hyperv/destroy dockerBackendV2`),并且描述中提到可以通过符号链接(symlink)在 `DataFolder` 参数中进行操作。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 是的,该漏洞允许攻击者通过特定 API 删除宿主机上的任意文件。这表明攻击者可以利用此漏洞破坏宿主机的文件系统,从而影响整个系统的稳定性,甚至可能波及其他容器的正常运行。 **结论:** 该 CVE 满足条件 1 和 2。 cve: ./data/2022/32xxx/CVE-2022-32250.json net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 提到 `user/net namespaces`,这表明它与 Linux 命名空间(namespace)机制相关。命名空间是容器技术(如 Docker)实现隔离的重要组成部分。 2. **是否会导致容器运行时影响其他容器或宿主机**: 有可能。由于该漏洞允许本地用户通过错误的 `NFT_STATEFUL_EXPR` 检查导致 use-after-free,从而实现权限提升到 root。如果攻击者在一个容器中利用此漏洞,可能突破容器的隔离限制,进而影响其他容器或宿主机的安全性。 **结论**:满足条件 1 和 2。 cve: ./data/2022/34xxx/CVE-2022-34292.json Docker Desktop for Windows before 4.6.0 allows attackers to overwrite any file through a symlink attack on the hyperv/create dockerBackendV2 API by controlling the DataFolder parameter for DockerDesktop.vhdx, a similar issue to CVE-2022-31647. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 描述中提到 Docker Desktop for Windows 的 API 存在一个问题,允许攻击者通过符号链接(symlink)攻击覆盖任意文件。这涉及到 Docker Desktop 的内部实现和虚拟磁盘文件(`DockerDesktop.vhdx`)的处理,因此与容器技术相关。然而,它并未直接涉及 namespace、cgroup 或容器隔离机制。 2. **分析是否会导致容器运行时影响其他容器或宿主机**: 根据描述,攻击者可以通过控制 `DataFolder` 参数来覆盖宿主机上的任意文件。这种行为会直接影响宿主机的安全性,可能会导致数据损坏或恶意代码注入,从而对整个系统造成威胁。因此,该漏洞确实可能导致容器运行时影响宿主机。 **结论**: - 条件 1 满足:与容器技术相关。 - 条件 2 满足:会影响宿主机。 无需返回 "N/A"。 cve: ./data/2022/34xxx/CVE-2022-34372.json Dell PowerProtect Cyber Recovery versions before 19.11.0.2 contain an authentication bypass vulnerability. A remote unauthenticated attacker may potentially access and interact with the docker registry API leading to an authentication bypass. The attacker may potentially alter the docker images leading to a loss of integrity and confidentiality analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息提到攻击者可以通过漏洞访问和交互 Docker Registry API,这直接与容器技术(Docker)相关。此外,提到攻击者可能篡改 Docker 镜像,这也涉及容器的完整性和机密性。 2. **是否会导致容器在运行时影响其他容器或宿主机**: 是的,攻击者通过此漏洞篡改 Docker 镜像后,可能导致以下后果: - 被篡改的镜像在运行时可能包含恶意代码,从而影响同一宿主机上的其他容器。 - 如果容器以特权模式运行或存在其他配置问题,可能进一步威胁到宿主机的安全。 因此,该漏洞可能间接导致容器之间的隔离被破坏,甚至威胁到宿主机的安全。 **结论**:满足条件1和条件2。 cve: ./data/2022/34xxx/CVE-2022-34918.json An issue was discovered in the Linux kernel through 5.18.9. A type confusion bug in nft_set_elem_init (leading to a buffer overflow) could be used by a local attacker to escalate privileges, a different vulnerability than CVE-2022-32250. (The attacker can obtain root access, but must start with an unprivileged user namespace to obtain CAP_NET_ADMIN access.) This can be fixed in nft_setelem_parse_data in net/netfilter/nf_tables_api.c. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,此漏洞与 namespace 相关。描述中明确提到攻击者需要从一个非特权用户命名空间(unprivileged user namespace)开始,以获取 `CAP_NET_ADMIN` 权限。这表明该漏洞利用了 Linux 命名空间的特性。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 有可能。由于该漏洞允许本地攻击者通过类型混淆漏洞和缓冲区溢出实现权限提升(获得 root 访问权限),如果攻击者在一个容器内利用此漏洞,则可能突破容器的隔离机制,影响宿主机或其他容器的安全性。特别是当容器使用非特权用户命名空间时,攻击者仍可能通过此漏洞获取更高的权限。 **结论**:满足条件 1 和 2。 cve: ./data/2022/36xxx/CVE-2022-36109.json Moby is an open-source project created by Docker to enable software containerization. A bug was found in Moby (Docker Engine) where supplementary groups are not set up properly. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. This bug is fixed in Moby (Docker Engine) 20.10.18. Running containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade, this problem can be worked around by not using the `"USER $USERNAME"` Dockerfile instruction. Instead by calling `ENTRYPOINT ["su", "-", "user"]` the supplementary groups will be set up properly. analysis: 1. **是否与 namespace、cgroup、container 或容器、隔离相关:** 是的,该 CVE 与容器相关。Moby(Docker Engine)是一个用于实现软件容器化的项目,问题涉及容器内的用户和组权限设置,这直接影响容器的隔离特性。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 在这种情况下,攻击者需要直接访问一个容器并操纵其补充组权限。虽然这可能允许攻击者在受影响的容器内绕过某些限制(例如访问敏感信息或执行代码),但没有明确证据表明此漏洞可以直接突破容器隔离,影响其他容器或宿主机。因此,该漏洞的影响主要限于单个容器内部。 **结论:** 条件 1 满足,条件 2 不完全满足(影响限于单个容器)。 cve: ./data/2022/37xxx/CVE-2022-37326.json Docker Desktop for Windows before 4.6.0 allows attackers to delete (or create) any file through the dockerBackendV2 windowscontainers/start API by controlling the pidfile field inside the DaemonJSON field in the WindowsContainerStartRequest class. This can indirectly lead to privilege escalation. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 提及了 Docker Desktop for Windows 的 `dockerBackendV2 windowscontainers/start API`,并且涉及对 `pidfile` 字段的控制。这表明问题与容器的启动配置和管理有关,因此与容器技术(container)相关。 2. **分析是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 攻击者可以通过控制 `pidfile` 字段来删除或创建任意文件,这种行为可能会直接影响宿主机的文件系统。如果攻击者利用此漏洞修改关键系统文件,可能会导致宿主机被完全控制或容器之间的隔离机制被破坏。因此,该漏洞可能导致容器运行时影响宿主机的安全性。 3. **结论**: 条件 1 和条件 2 均满足,因此返回以下分析结果: - 与容器和隔离相关。 - 可能会导致容器运行时影响其他容器或宿主机。 cve: ./data/2022/38xxx/CVE-2022-38730.json Docker Desktop for Windows before 4.6 allows attackers to overwrite any file through the windowscontainers/start dockerBackendV2 API by controlling the data-root field inside the DaemonJSON field in the WindowsContainerStartRequest class. This allows exploiting a symlink vulnerability in ..\dataRoot\network\files\local-kv.db because of a TOCTOU race condition. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE与容器技术相关。它涉及到Docker Desktop for Windows中的`dockerBackendV2 API`,并且通过控制`DaemonJSON`字段中的`data-root`,可以利用符号链接漏洞影响容器的文件系统配置。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器逃逸或影响宿主机。攻击者可以通过覆盖宿主机上的任意文件(如`local-kv.db`),利用TOCTOU(Time-of-check to time-of-use)竞争条件漏洞,进而可能影响其他容器或宿主机的安全性。 3. **结论**: 由于条件1和条件2均满足,因此不需要返回"N/A"。 cve: ./data/2022/39xxx/CVE-2022-39206.json Onedev is an open source, self-hosted Git Server with CI/CD and Kanban. When using Docker-based job executors, the Docker socket (e.g. /var/run/docker.sock on Linux) is mounted into each Docker step. Users that can define and trigger CI/CD jobs on a project could use this to control the Docker daemon on the host machine. This is a known dangerous pattern, as it can be used to break out of Docker containers and, in most cases, gain root privileges on the host system. This issue allows regular (non-admin) users to potentially take over the build infrastructure of a OneDev instance. Attackers need to have an account (or be able to register one) and need permission to create a project. Since code.onedev.io has the right preconditions for this to be exploited by remote attackers, it could have been used to hijack builds of OneDev itself, e.g. by injecting malware into the docker images that are built and pushed to Docker Hub. The impact is increased by this as described before. Users are advised to upgrade to 7.3.0 or higher. There are no known workarounds for this issue. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 描述中明确提到 Docker 容器的使用场景,尤其是 `/var/run/docker.sock` 被挂载到容器中。这涉及到容器的隔离性问题,因为通过访问 Docker 套接字,用户可以与宿主机上的 Docker 守护进程交互,从而突破容器的隔离。 2. **分析是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 是的,该漏洞会导致容器突破隔离,影响宿主机甚至其他容器。攻击者可以通过控制 Docker 守护进程,在宿主机上执行任意命令,或者创建、删除、修改其他容器。这种行为可能会导致宿主机被完全控制,并可能进一步影响同一宿主机上的其他容器。 3. **结论**: 由于条件 1 和条件 2 都满足,因此返回以下分析结果: - 与容器隔离相关:是 - 可能影响其他容器或宿主机:是 cve: ./data/2022/39xxx/CVE-2022-39321.json GitHub Actions Runner is the application that runs a job from a GitHub Actions workflow. The actions runner invokes the docker cli directly in order to run job containers, service containers, or container actions. A bug in the logic for how the environment is encoded into these docker commands was discovered in versions prior to 2.296.2, 2.293.1, 2.289.4, 2.285.2, and 2.283.4 that allows an input to escape the environment variable and modify that docker command invocation directly. Jobs that use container actions, job containers, or service containers alongside untrusted user inputs in environment variables may be vulnerable. The Actions Runner has been patched, both on `github.com` and hotfixes for GHES and GHAE customers in versions 2.296.2, 2.293.1, 2.289.4, 2.285.2, and 2.283.4. GHES and GHAE customers may want to patch their instance in order to have their runners automatically upgrade to these new runner versions. As a workaround, users may consider removing any container actions, job containers, or service containers from their jobs until they are able to upgrade their runner versions. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE与容器相关。问题涉及GitHub Actions Runner在调用Docker CLI时,由于环境变量编码逻辑的漏洞,可能导致恶意输入篡改Docker命令的执行。这直接影响到容器的运行方式。 2. **是否会导致容器(如Docker)在运行时影响其他容器或宿主机**: 是的,该漏洞可能会影响其他容器或宿主机。如果攻击者能够利用此漏洞修改Docker命令的执行,他们可能会绕过预期的隔离机制,从而对宿主机或其他容器造成潜在威胁。例如,通过篡改Docker命令,攻击者可能注入恶意参数,导致容器以非预期的方式运行,甚至可能逃逸到宿主机。 3. **结论**: 由于条件1和条件2均满足,因此返回上述分析结果。 cve: ./data/2022/41xxx/CVE-2022-41737.json IBM Storage Scale Container Native Storage Access 5.1.2.1 through 5.1.7.0 could allow a local attacker to initiate connections from a container outside the current namespace. IBM X-Force ID: 237811. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE明确提到“initiate connections from a container outside the current namespace”,即从容器中发起连接到当前命名空间之外的目标。这直接涉及到了容器的命名空间(namespace)隔离机制。 2. **是否会导致容器在运行时影响其他容器或宿主机**: 是的,由于该漏洞允许容器突破其当前的命名空间限制,可能会导致容器访问或影响其他容器或宿主机上的资源。这种行为破坏了容器之间的隔离性,可能带来安全风险。 因此,该CVE满足条件1和条件2。 cve: ./data/2022/41xxx/CVE-2022-41939.json knative.dev/func is is a client library and CLI enabling the development and deployment of Kubernetes functions. Developers using a malicious or compromised third-party buildpack could expose their registry credentials or local docker socket to a malicious `lifecycle` container. This issues has been patched in PR #1442, and is part of release 1.8.1. This issue only affects users who are using function buildpacks from third-parties; pinning the builder image to a specific content-hash with a valid `lifecycle` image will also mitigate the attack. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与容器和隔离相关。描述中提到“expose their registry credentials or local docker socket to a malicious `lifecycle` container”,表明问题涉及将敏感信息(如 Docker Socket)暴露给恶意的容器。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 是的,这可能导致影响。如果攻击者利用此漏洞,通过恶意的 `lifecycle` 容器访问本地 Docker Socket,他们可以进一步控制宿主机上的其他容器或直接对宿主机进行攻击。这种行为破坏了容器之间的隔离性,并可能危及整个容器化环境的安全。 **结论:** 满足条件 1 和 2。 cve: ./data/2022/42xxx/CVE-2022-42919.json Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-default configuration. The Python multiprocessing library, when used with the forkserver start method on Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which in many system configurations means any user on the same machine. Pickles can execute arbitrary code. Thus, this allows for local user privilege escalation to the user that any forkserver process is running as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start method for multiprocessing is not the default start method. This issue is Linux specific because only Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract namespace sockets by default. Support for users manually specifying an abstract namespace socket was added as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do that in CPython before 3.9. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 涉及 Linux 的机器本地网络命名空间(machine local network namespace),并且提到 Linux 抽象命名空间套接字(abstract namespace sockets)。虽然它提到了命名空间,但这里的命名空间是指 Linux 的 socket 抽象命名空间,而不是与容器隔离直接相关的 mount namespace、PID namespace 等。因此,这个漏洞并不直接与容器或隔离技术(如 cgroup、namespace)相关。 2. **分析是否会导致容器运行时影响其他容器或宿主机**: 该漏洞主要影响使用 Python `multiprocessing` 库的程序,并且需要特定配置(`forkserver` 启动方法和抽象命名空间套接字)。此漏洞允许在相同机器上的用户通过反序列化 pickles 执行任意代码,从而实现权限提升。然而,这种攻击的前提是攻击者已经能够在目标机器上运行代码。在容器环境中,如果容器没有共享宿主机的网络命名空间(即容器有自己的独立网络命名空间),那么攻击范围将被限制在容器内部,不会直接影响其他容器或宿主机。因此,该漏洞在默认容器配置下不会直接导致容器影响其他容器或宿主机。 3. **结论**: 根据以上分析,该 CVE 不满足条件 1 和条件 2,因此返回: **N/A** cve: ./data/2022/46xxx/CVE-2022-46167.json Capsule is a multi-tenancy and policy-based framework for Kubernetes. Prior to version 0.1.3, a ServiceAccount deployed in a Tenant Namespace, when granted with `PATCH` capabilities on its own Namespace, is able to edit it and remove the Owner Reference, breaking the reconciliation of the Capsule Operator and removing all the enforcement like Pod Security annotations, Network Policies, Limit Range and Resource Quota items. An attacker could detach the Namespace from a Tenant that is forbidding starting privileged Pods using the Pod Security labels by removing the OwnerReference, removing the enforcement labels, and being able to start privileged containers that would be able to start a generic Kubernetes privilege escalation. Patches have been released for version 0.1.3. No known workarounds are available. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,此 CVE 与 namespace 和容器隔离相关。问题的核心在于 Kubernetes 的多租户框架 Capsule 中,ServiceAccount 在特定权限下可以修改其所在 Namespace 的 Owner Reference,从而破坏 Capsule Operator 的协调机制,并移除诸如 Pod Security 标签、网络策略等强制执行的安全措施。这直接影响了 namespace 的隔离性,使得攻击者可以在不受限制的情况下启动特权容器。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 是的,此漏洞可能导致容器运行时影响其他容器或宿主机。通过移除 Owner Reference 和安全标签,攻击者可以启动特权容器,这种容器能够突破默认的隔离机制,访问宿主机资源或干扰其他容器的正常运行。这可能会导致宿主机上的敏感信息泄露、资源滥用,甚至进一步的权限提升和系统控制。 **结论:满足条件 1 和 2。** cve: ./data/2022/47xxx/CVE-2022-47952.json lxc-user-nic in lxc through 5.0.1 is installed setuid root, and may allow local users to infer whether any file exists, even within a protected directory tree, because "Failed to open" often indicates that a file does not exist, whereas "does not refer to a network namespace path" often indicates that a file exists. NOTE: this is different from CVE-2018-6556 because the CVE-2018-6556 fix design was based on the premise that "we will report back to the user that the open() failed but the user has no way of knowing why it failed"; however, in many realistic cases, there are no plausible reasons for failing except that the file does not exist. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关:** 该 CVE 提到 `lxc-user-nic`,这是一个与 LXC(Linux Containers)相关的工具。LXC 是一种轻量级的容器技术,依赖于 Linux 的 namespaces 和 cgroups 实现隔离。因此,这个 CVE 明确与容器和 namespace 相关。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 根据描述,该漏洞允许本地用户通过错误消息推断某个文件是否存在。这种信息泄露可能会被攻击者利用来获取敏感路径的信息,但并没有提到直接的权限提升或对宿主机或其他容器的直接影响。然而,由于它涉及 LXC 的网络命名空间管理工具 (`lxc-user-nic`),如果攻击者能够利用此漏洞进一步探索系统,可能会间接威胁到容器隔离性或宿主机的安全性。 3. **结论:** 条件 1 和条件 2 部分满足,因此返回以下分析结果: - 与 namespace 和容器技术相关。 - 可能间接影响容器隔离性,但需要结合其他攻击手段才能对宿主机或其他容器造成实质性威胁。 cve: ./data/2022/48xxx/CVE-2022-48638.json In the Linux kernel, the following vulnerability has been resolved: cgroup: cgroup_get_from_id() must check the looked-up kn is a directory cgroup has to be one kernfs dir, otherwise kernel panic is caused, especially cgroup id is provide from userspace. analysis: 1. 该 CVE 信息与 namespace、cgroup、container 或容器、隔离相关。 - 描述中明确提到 `cgroup` 和 `kernfs dir`,并且涉及用户空间提供的 cgroup ID,这表明它与 cgroup 的实现和使用有关。 - cgroup 是 Linux 容器(如 Docker)实现资源限制和隔离的重要组成部分。 2. 该 CVE 可能会导致容器在运行时影响其他容器或宿主机。 - 如果 `cgroup_get_from_id()` 没有正确检查查找的 kernfs 节点是否为目录,可能会导致内核崩溃(kernel panic)。这种问题可能被恶意用户利用,通过提供无效或恶意构造的 cgroup ID 来触发内核崩溃。 - 在共享内核的容器环境中(如 Docker),这种漏洞可能允许一个容器影响其他容器或宿主机的稳定性。 结论:满足条件 1 和 2。 cve: ./data/2022/48xxx/CVE-2022-48671.json In the Linux kernel, the following vulnerability has been resolved: cgroup: Add missing cpus_read_lock() to cgroup_attach_task_all() syzbot is hitting percpu_rwsem_assert_held(&cpu_hotplug_lock) warning at cpuset_attach() [1], for commit 4f7e7236435ca0ab ("cgroup: Fix threadgroup_rwsem <-> cpus_read_lock() deadlock") missed that cpuset_attach() is also called from cgroup_attach_task_all(). Add cpus_read_lock() like what cgroup_procs_write_start() does. analysis: 1. 该 CVE 信息与 cgroup 相关,因为它涉及到 `cgroup_attach_task_all()` 函数以及 `cpus_read_lock()` 的使用。Cgroup 是 Linux 内核中的一个功能模块,用于限制、控制和隔离进程组的资源使用(如 CPU、内存等),并且是容器技术(如 Docker)实现资源隔离的重要组成部分。 2. 尽管该漏洞涉及 cgroup,但它主要是关于内核中锁机制的正确性问题(`percpu_rwsem_assert_held(&cpu_hotplug_lock)` 警告)。从描述来看,这个问题并不会直接影响容器的隔离性或导致一个容器影响其他容器或宿主机。它更像是一个内核代码路径的健壮性修复,而不是安全漏洞。 **结论**: N/A cve: ./data/2022/48xxx/CVE-2022-48757.json In the Linux kernel, the following vulnerability has been resolved: net: fix information leakage in /proc/net/ptype In one net namespace, after creating a packet socket without binding it to a device, users in other net namespaces can observe the new `packet_type` added by this packet socket by reading `/proc/net/ptype` file. This is minor information leakage as packet socket is namespace aware. Add a net pointer in `packet_type` to keep the net namespace of of corresponding packet socket. In `ptype_seq_show`, this net pointer must be checked when it is not NULL. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE与namespace相关。具体来说,它涉及网络命名空间(net namespace)。问题发生在创建一个未绑定到设备的packet socket时,其他网络命名空间中的用户可以观察到该packet socket添加的`packet_type`信息。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 该漏洞导致的是信息泄露问题,而非权限提升或直接破坏隔离性的问题。虽然其他网络命名空间中的用户可以观察到新增的`packet_type`,但这只是轻微的信息泄露,并不会直接影响其他容器或宿主机的安全性。然而,在多租户环境中,这种信息泄露可能会被用于推测某些敏感信息,因此仍需注意。 **结论**:满足条件1和条件2的部分要求,但影响程度有限。 cve: ./data/2022/48xxx/CVE-2022-48799.json In the Linux kernel, the following vulnerability has been resolved: perf: Fix list corruption in perf_cgroup_switch() There's list corruption on cgrp_cpuctx_list. This happens on the following path: perf_cgroup_switch: list_for_each_entry(cgrp_cpuctx_list) cpu_ctx_sched_in ctx_sched_in ctx_pinned_sched_in merge_sched_in perf_cgroup_event_disable: remove the event from the list Use list_for_each_entry_safe() to allow removing an entry during iteration. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,这个 CVE 与 cgroup 相关。问题出现在 `perf_cgroup_switch()` 函数中,涉及到 `cgrp_cpuctx_list` 的列表操作。Cgroups(控制组)是 Linux 内核中的一个功能,用于限制、控制和隔离进程组的资源使用(如 CPU、内存、磁盘 I/O 等)。Perf 工具利用 cgroups 来对性能事件进行分组管理。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 可能会。由于该漏洞涉及 cgroup 的列表操作,如果出现列表损坏(list corruption),可能会导致以下后果: - 在多租户环境中(例如容器编排系统 Kubernetes 中),不同容器之间的资源监控和限制可能失效。 - 如果容器内的进程触发了该漏洞,可能会导致宿主机上的 cgroup 数据结构损坏,从而影响整个系统的稳定性,甚至可能导致宿主机崩溃。 - 攻击者可能利用此漏洞逃逸容器环境,影响宿主机或其他容器。 因此,该漏洞有可能影响容器的隔离性,并对宿主机和其他容器造成潜在威胁。 **结论**:满足条件 1 和条件 2。 cve: ./data/2022/48xxx/CVE-2022-48944.json In the Linux kernel, the following vulnerability has been resolved: sched: Fix yet more sched_fork() races Where commit 4ef0c5c6b5ba ("kernel/sched: Fix sched_fork() access an invalid sched_task_group") fixed a fork race vs cgroup, it opened up a race vs syscalls by not placing the task on the runqueue before it gets exposed through the pidhash. Commit 13765de8148f ("sched/fair: Fix fault in reweight_entity") is trying to fix a single instance of this, instead fix the whole class of issues, effectively reverting this commit. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关** 该 CVE 描述中提到 `sched_fork()` 函数中的竞争条件问题,并且明确提到了 `cgroup`(控制组)。因此,此漏洞与 cgroup 相关,而 cgroup 是容器技术(如 Docker)实现资源隔离的重要组成部分。所以,该 CVE 与容器和隔离机制有一定关联。 2. **分析是否会导致容器在运行时影响其他容器或宿主机** 该漏洞涉及 `sched_fork()` 函数的竞争条件问题,可能导致任务在被加入运行队列之前通过 `pidhash` 暴露出来。这种问题可能会影响调度器的行为,进而可能导致任务分配或资源管理的异常。由于 `cgroup` 是容器资源限制的核心机制,如果该漏洞被利用,可能会导致容器逃逸或影响宿主机的资源分配,从而影响其他容器或宿主机的安全性。 3. **结论** 根据以上分析,该 CVE 信息满足条件 1 和条件 2。 cve: ./data/2022/48xxx/CVE-2022-48988.json In the Linux kernel, the following vulnerability has been resolved: memcg: fix possible use-after-free in memcg_write_event_control() memcg_write_event_control() accesses the dentry->d_name of the specified control fd to route the write call. As a cgroup interface file can't be renamed, it's safe to access d_name as long as the specified file is a regular cgroup file. Also, as these cgroup interface files can't be removed before the directory, it's safe to access the parent too. Prior to 347c4a874710 ("memcg: remove cgroup_event->cft"), there was a call to __file_cft() which verified that the specified file is a regular cgroupfs file before further accesses. The cftype pointer returned from __file_cft() was no longer necessary and the commit inadvertently dropped the file type check with it allowing any file to slip through. With the invarients broken, the d_name and parent accesses can now race against renames and removals of arbitrary files and cause use-after-free's. Fix the bug by resurrecting the file type check in __file_cft(). Now that cgroupfs is implemented through kernfs, checking the file operations needs to go through a layer of indirection. Instead, let's check the superblock and dentry type. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,这个 CVE 信息与 cgroup 相关。问题出现在 `memcg_write_event_control()` 函数中,该函数用于处理 cgroup 的内存控制功能。具体来说,问题涉及对 cgroup 接口文件的操作,包括文件名访问 (`dentry->d_name`) 和父目录访问。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机** 可能会。由于该漏洞允许任意文件通过检查,并可能导致竞争条件(race condition),从而引发 use-after-free 问题。如果攻击者能够利用此漏洞,在容器环境中可能会影响其他容器或宿主机的安全性。例如,use-after-free 漏洞可能会被利用来执行任意代码或导致系统崩溃。虽然 cgroup 本身主要用于资源限制和隔离,但这种类型的漏洞可能会破坏隔离机制,进而影响整个系统的稳定性或安全性。 因此,基于以上分析,该 CVE 满足条件 1 和条件 2。 cve: ./data/2022/49xxx/CVE-2022-49266.json In the Linux kernel, the following vulnerability has been resolved: block: fix rq-qos breakage from skipping rq_qos_done_bio() a647a524a467 ("block: don't call rq_qos_ops->done_bio if the bio isn't tracked") made bio_endio() skip rq_qos_done_bio() if BIO_TRACKED is not set. While this fixed a potential oops, it also broke blk-iocost by skipping the done_bio callback for merged bios. Before, whether a bio goes through rq_qos_throttle() or rq_qos_merge(), rq_qos_done_bio() would be called on the bio on completion with BIO_TRACKED distinguishing the former from the latter. rq_qos_done_bio() is not called for bios which wenth through rq_qos_merge(). This royally confuses blk-iocost as the merged bios never finish and are considered perpetually in-flight. One reliably reproducible failure mode is an intermediate cgroup geting stuck active preventing its children from being activated due to the leaf-only rule, leading to loss of control.

As this tracking can be expensive, it is disabled when no cgroup has iolatency configured for the device. To ensure that the inflight counters stay balanced, iolatency_set_limit() freezes the request_queue while manipulating the enabled counter, which ensures that no IO is in flight and thus all counters are zero. Unfortunately, iolatency_set_limit() isn't the only place where the enabled counter is manipulated. iolatency_pd_offline() can also dec the counter and trigger disabling. As this disabling happens without freezing the q, this can easily happen while some IOs are in flight and thus leak the counts. This can be easily demonstrated by turning on iolatency on an one empty cgroup while IOs are in flight in other cgroups and then removing the cgroup. Note that iolatency shouldn't have been enabled elsewhere in the system to ensure that removing the cgroup disables iolatency for the whole device. The following keeps flipping on and off iolatency on sda: echo +io > /sys/fs/cgroup/cgroup.subtree_control while true; do mkdir -p /sys/fs/cgroup/test echo '8:0 target=100000' > /sys/fs/cgroup/test/io.latency sleep 1 rmdir /sys/fs/cgroup/test sleep 1 done and there's concurrent fio generating direct rand reads: fio --name test --filename=/dev/sda --direct=1 --rw=randread \ --runtime=600 --time_based --iodepth=256 --numjobs=4 --bs=4k while monitoring with the following drgn script: while True: for css in css_for_each_descendant_pre(prog['blkcg_root'].css.address_of_()): for pos in hlist_for_each(container_of(css, 'struct blkcg', 'css').blkg_list): blkg = container_of(pos, 'struct blkcg_gq', 'blkcg_node') pd = blkg.pd[prog['blkcg_policy_iolatency'].plid] if pd.value_() == 0: continue iolat = container_of(pd, 'struct iolatency_grp', 'pd') inflight = iolat.rq_wait.inflight.counter.value_() if inflight: print(f'inflight={inflight} {disk_name(blkg.q.disk).decode("utf-8")} ' f'{cgroup_path(css.cgroup).decode("utf-8")}') time.sleep(1) The monitoring output looks like the following: inflight=1 sda /user.slice inflight=1 sda /user.slice ... inflight=14 sda /user.slice inflight=13 sda /user.slice inflight=17 sda /user.slice inflight=15 sda /user.slice inflight=18 sda /user.slice inflight=17 sda /user.slice inflight=20 sda /user.slice inflight=19 sda /user.slice <- fio stopped, inflight stuck at 19 inflight=19 sda /user.slice inflight=19 sda /user.slice If a cgroup with stuck inflight ends up getting throttled, the throttled IOs will never get issued as there's no completion event to wake it up leading to an indefinite hang. This patch fixes the bug by unifying enable handling into a work item which is automatically kicked off from iolatency_set_min_lat_nsec() which is called from both iolatency_set_limit() and iolatency_pd_offline() paths. Punting to a work item is necessary as iolatency_pd_offline() is called under spinlocks while freezing a request_queue requires a sleepable context. This also simplifies the code reducing LOC sans the comments and avoids the unnecessary freezes which were happening whenever a cgroup's latency target is newly set or cleared. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,这个 CVE 信息与 cgroup 直接相关。漏洞描述中提到 `iolatency` 是基于 cgroup 的机制,用于跟踪每个 cgroup 的 inflight IO 数量。此外,问题的核心在于 `iolatency_pd_offline()` 和 `iolatency_set_limit()` 操控 enabled 计数器时未正确同步,导致 inflight 计数不平衡。 2. **分析是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 可能会。由于该漏洞涉及 cgroup 的 IO 调度机制,如果一个容器的 cgroup 配置受到影响(例如 inflight 计数不平衡),可能会导致该容器的 IO 被错误地限制或挂起,从而间接影响宿主机或其他容器的正常运行。特别是当某个 cgroup 的 inflight 计数卡住时,可能导致 IO 挂起,进一步影响整个系统的稳定性。 3. **结论**: 条件 1 和条件 2 均满足,因此需要返回上述分析内容。 cve: ./data/2022/49xxx/CVE-2022-49411.json In the Linux kernel, the following vulnerability has been resolved: bfq: Make sure bfqg for which we are queueing requests is online Bios queued into BFQ IO scheduler can be associated with a cgroup that was already offlined. This may then cause insertion of this bfq_group into a service tree. But this bfq_group will get freed as soon as last bio associated with it is completed leading to use after free issues for service tree users. Fix the problem by making sure we always operate on online bfq_group. If the bfq_group associated with the bio is not online, we pick the first online parent. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 cgroup 相关。问题描述中提到 BFQ I/O 调度器中的 `bfq_group` 可能与一个已经被 offlined 的 cgroup 关联,这表明问题涉及到 cgroup 的生命周期管理。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 这个漏洞可能导致 use-after-free 问题,从而可能引发系统不稳定或崩溃。虽然问题本身直接涉及的是 cgroup 和 I/O 调度器,但如果容器使用了受影响的 BFQ 调度器,并且其 cgroup 被 offlined,可能会导致容器的 I/O 操作影响到宿主机或其他容器的稳定性。因此,这种漏洞在某些情况下可能会影响容器隔离性。 **结论:** 该 CVE 信息满足条件 1 和条件 2。 cve: ./data/2022/49xxx/CVE-2022-49412.json In the Linux kernel, the following vulnerability has been resolved: bfq: Avoid merging queues with different parents It can happen that the parent of a bfqq changes between the moment we decide two queues are worth to merge (and set bic->stable_merge_bfqq) and the moment bfq_setup_merge() is called. This can happen e.g. because the process submitted IO for a different cgroup and thus bfqq got reparented. It can even happen that the bfqq we are merging with has parent cgroup that is already offline and going to be destroyed in which case the merge can lead to use-after-free issues such as: BUG: KASAN: use-after-free in __bfq_deactivate_entity+0x9cb/0xa50 Read of size 8 at addr ffff88800693c0c0 by task runc:[2:INIT]/10544 CPU: 0 PID: 10544 Comm: runc:[2:INIT] Tainted: G E 5.15.2-0.g5fb85fd-default #1 openSUSE Tumbleweed (unreleased) f1f3b891c72369aebecd2e43e4641a6358867c70 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.14.0-0-g155821a-rebuilt.opensuse.org 04/01/2014 Call Trace: dump_stack_lvl+0x46/0x5a print_address_description.constprop.0+0x1f/0x140 ? __bfq_deactivate_entity+0x9cb/0xa50 kasan_report.cold+0x7f/0x11b ? __bfq_deactivate_entity+0x9cb/0xa50 __bfq_deactivate_entity+0x9cb/0xa50 ? update_curr+0x32f/0x5d0 bfq_deactivate_entity+0xa0/0x1d0 bfq_del_bfqq_busy+0x28a/0x420 ? resched_curr+0x116/0x1d0 ? bfq_requeue_bfqq+0x70/0x70 ? check_preempt_wakeup+0x52b/0xbc0 __bfq_bfqq_expire+0x1a2/0x270 bfq_bfqq_expire+0xd16/0x2160 ? try_to_wake_up+0x4ee/0x1260 ? bfq_end_wr_async_queues+0xe0/0xe0 ? _raw_write_unlock_bh+0x60/0x60 ? _raw_spin_lock_irq+0x81/0xe0 bfq_idle_slice_timer+0x109/0x280 ? bfq_dispatch_request+0x4870/0x4870 __hrtimer_run_queues+0x37d/0x700 ? enqueue_hrtimer+0x1b0/0x1b0 ? kvm_clock_get_cycles+0xd/0x10 ? ktime_get_update_offsets_now+0x6f/0x280 hrtimer_interrupt+0x2c8/0x740 Fix the problem by checking that the parent of the two bfqqs we are merging in bfq_setup_merge() is the same. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该漏洞与 cgroup 相关。具体来说,问题出现在 I/O 调度器 BFQ(Budget Fair Queuing)中,涉及到不同 cgroup 的队列合并操作。当一个进程为不同的 cgroup 提交 I/O 请求时,可能导致队列被重新分配父级 cgroup,从而引发潜在的使用后释放(use-after-free)问题。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机** 是的,该漏洞可能会影响容器的隔离性。由于 cgroup 是容器资源隔离的核心机制之一,BFQ 队列的错误合并可能导致对已销毁 cgroup 的引用,进而引发 use-after-free 问题。这可能会导致容器逃逸或影响宿主机的稳定性,尤其是在多租户环境中,不同容器共享同一宿主机的情况下。 3. **结论** 条件 1 和条件 2 均满足,因此需要返回上述分析内容。 cve: ./data/2022/49xxx/CVE-2022-49413.json In the Linux kernel, the following vulnerability has been resolved: bfq: Update cgroup information before merging bio When the process is migrated to a different cgroup (or in case of writeback just starts submitting bios associated with a different cgroup) bfq_merge_bio() can operate with stale cgroup information in bic. Thus the bio can be merged to a request from a different cgroup or it can result in merging of bfqqs for different cgroups or bfqqs of already dead cgroups and causing possible use-after-free issues. Fix the problem by updating cgroup information in bfq_merge_bio(). analysis: 1. 该 CVE 信息与 namespace、cgroup、container 或容器、隔离相关。 分析:漏洞描述中明确提到 cgroup(控制组)的概念,并且问题出现在当进程迁移到不同的 cgroup 或者与不同 cgroup 关联的 bio 提交时,可能导致错误的合并操作。这表明问题直接涉及 cgroup 的管理。 2. 该 CVE 不会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机。 分析:虽然该漏洞涉及 cgroup,但其影响主要集中在 I/O 调度器 BFQ(Budget Fair Queuing)的实现上。具体来说,问题是由于过时的 cgroup 信息导致 bio 合并错误,可能引发 use-after-free 问题。然而,这种问题的影响范围限制在内核的 I/O 调度逻辑中,不会直接影响容器之间的隔离性或对宿主机的安全性造成威胁。 结论:满足条件 1,但不满足条件 2。 cve: ./data/2022/49xxx/CVE-2022-49567.json In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix uninit-value in mpol_rebind_policy() mpol_set_nodemask()(mm/mempolicy.c) does not set up nodemask when pol->mode is MPOL_LOCAL.

When we're moving tasks around across csets for a migration, we need to hold the source and destination csets to ensure that they don't go away while we're moving tasks about. This is done by linking cset->mg_preload_node on either the mgctx->preloaded_src_csets or mgctx->preloaded_dst_csets list. Using the same cset->mg_preload_node for both the src and dst lists was deemed okay as a cset can't be both the source and destination at the same time. Unfortunately, this overloading becomes problematic when multiple tasks are involved in a migration and some of them are identity noop migrations while others are actually moving across cgroups. For example, this can happen with the following sequence on cgroup1: #1> mkdir -p /sys/fs/cgroup/misc/a/b #2> echo $$ > /sys/fs/cgroup/misc/a/cgroup.procs #3> RUN_A_COMMAND_WHICH_CREATES_MULTIPLE_THREADS & #4> PID=$! #5> echo $PID > /sys/fs/cgroup/misc/a/b/tasks #6> echo $PID > /sys/fs/cgroup/misc/a/cgroup.procs the process including the group leader back into a. In this final migration, non-leader threads would be doing identity migration while the group leader is doing an actual one. After #3, let's say the whole process was in cset A, and that after #4, the leader moves to cset B. Then, during #6, the following happens: 1. cgroup_migrate_add_src() is called on B for the leader. 2. cgroup_migrate_add_src() is called on A for the other threads. 3. cgroup_migrate_prepare_dst() is called. It scans the src list. 4. It notices that B wants to migrate to A, so it tries to A to the dst list but realizes that its ->mg_preload_node is already busy. 5. and then it notices A wants to migrate to A as it's an identity migration, it culls it by list_del_init()'ing its ->mg_preload_node and putting references accordingly. 6. The rest of migration takes place with B on the src list but nothing on the dst list. This means that A isn't held while migration is in progress. If all tasks leave A before the migration finishes and the incoming task pins it, the cset will be destroyed leading to use-after-free. This is caused by overloading cset->mg_preload_node for both src and dst preload lists. We wanted to exclude the cset from the src list but ended up inadvertently excluding it from the dst list too. This patch fixes the issue by separating out cset->mg_preload_node into ->mg_src_preload_node and ->mg_dst_preload_node, so that the src and dst preloadings don't interfere with each other. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该 CVE 信息明确与 cgroup(控制组)相关。cgroup 是 Linux 内核中的一个特性,用于限制、记录和隔离进程组的资源(如 CPU、内存、磁盘 I/O 等)。此漏洞涉及 cgroup 的迁移逻辑,特别是 css_set(control group subsystem set)在任务迁移时的处理问题。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机** 可能会。由于此漏洞涉及到 cgroup 的任务迁移逻辑,而 cgroup 是容器技术(如 Docker、Kubernetes 等)实现资源隔离的核心机制之一,因此如果漏洞被利用,可能会导致以下问题: - 在多租户环境中,一个容器内的任务迁移操作可能会影响其他容器的任务迁移逻辑,进而可能导致资源分配错误或隔离失效。 - 如果宿主机上的 cgroup 配置受到影响,可能会间接影响到宿主机的稳定性或安全性,例如导致资源竞争或内核崩溃。 3. **结论** 根据上述分析,条件 1 和条件 2 均满足,因此返回分析结果而非 "N/A"。 cve: ./data/2023/0xxx/CVE-2023-0627.json Docker Desktop 4.11.x allows --no-windows-containers flag bypass via IPC response spoofing which may lead to Local Privilege Escalation (LPE).This issue affects Docker Desktop: 4.11.X. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器技术相关。具体来说,它涉及 Docker Desktop 的 Windows 容器功能,并通过 IPC(进程间通信)响应伪造绕过 `--no-windows-containers` 标志。 2. **是否会导致容器在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致本地权限提升 (LPE),从而允许攻击者通过 IPC 响应伪造绕过限制,进而影响宿主机的安全性。这种情况下,攻击者可能利用该漏洞突破容器隔离,对宿主机或其他容器造成潜在威胁。 **结论**:满足条件 1 和 2。 cve: ./data/2023/0xxx/CVE-2023-0628.json Docker Desktop before 4.17.0 allows an attacker to execute an arbitrary command inside a Dev Environments container during initialization by tricking a user to open a crafted malicious docker-desktop:// URL. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该CVE明确提到了Docker Desktop和Dev Environments容器,这表明它与容器技术相关。此外,问题涉及在容器初始化期间执行任意命令,这也与容器的隔离性有关。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机:** 有可能。通过利用此漏洞,攻击者可以在Dev Environments容器中执行任意命令。如果该容器没有正确配置隔离机制(例如共享了宿主机的命名空间或资源),则可能会进一步影响其他容器或宿主机的安全性。 **结论:** 满足条件1和条件2,需要关注此漏洞对容器隔离性和宿主机安全的影响。 cve: ./data/2023/0xxx/CVE-2023-0629.json Docker Desktop before 4.17.0 allows an unprivileged user to bypass Enhanced Container Isolation (ECI) restrictions by setting the Docker host to docker.raw.sock, or npipe:////.pipe/docker_engine_linux on Windows, via the -H (--host) CLI flag or the DOCKER_HOST environment variable and launch containers without the additional hardening features provided by ECI. This would not affect already running containers, nor containers launched through the usual approach (without Docker's raw socket). The affected functionality is available for Docker Business customers only and assumes an environment where users are not granted local root or Administrator privileges. This issue has been fixed in Docker Desktop 4.17.0. Affected Docker Desktop versions: from 4.13.0 before 4.17.0. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,这个 CVE 与容器隔离相关。它描述了 Docker Desktop 的 Enhanced Container Isolation (ECI) 功能存在漏洞,允许未授权用户通过特定方式绕过 ECI 提供的额外隔离和加固功能。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 是的,此漏洞可能会导致容器隔离失效。攻击者可以通过设置 `docker.raw.sock` 或类似方法绕过 ECI 的限制,从而可能以较低的安全性启动容器。这可能间接影响其他容器或宿主机的安全性,因为缺少 ECI 提供的加固措施可能导致更高的风险暴露。 **结论:满足条件 1 和 2。** cve: ./data/2023/0xxx/CVE-2023-0923.json A flaw was found in the Kubernetes service for notebooks in RHODS, where it does not prevent pods from other namespaces and applications from making requests to the Jupyter API. This flaw can lead to file content exposure and other issues. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,这个 CVE 信息与 namespace 和容器隔离相关。问题在于 Kubernetes 服务未能正确限制其他命名空间中的 Pods 对 Jupyter API 的访问,这表明跨命名空间的隔离存在漏洞。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 这个漏洞可能会导致一个命名空间中的容器通过未受限制的 API 请求访问另一个命名空间中容器的数据(如文件内容)。因此,虽然它不会直接影响宿主机,但它确实可能导致一个容器或 Pod 泄露敏感信息给其他容器或 Pod。 **结论:满足条件 1 和 2。** cve: ./data/2023/1xxx/CVE-2023-1174.json This vulnerability exposes a network port in minikube running on macOS with Docker driver that could enable unexpected remote access to the minikube container. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞与容器和隔离相关。描述中提到的是 minikube 在 macOS 上使用 Docker 驱动时暴露出一个网络端口,这直接影响到 minikube 容器的网络隔离性。 2. **分析是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 是的,可能会产生影响。由于网络端口被意外暴露,攻击者可能通过此端口访问 minikube 容器,并进一步利用该容器作为跳板,尝试访问同一宿主机上的其他容器或直接攻击宿主机。这种行为破坏了容器之间的隔离性,也可能对宿主机的安全性构成威胁。 因此,条件 1 和 2 均满足。 cve: ./data/2023/1xxx/CVE-2023-1555.json An issue has been discovered in GitLab affecting all versions starting from 15.2 before 16.1.5, all versions starting from 16.2 before 16.2.5, all versions starting from 16.3 before 16.3.1. A namespace-level banned user can access the API. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关:** 该 CVE 描述提到“namespace-level banned user can access the API”,表明问题与 namespace 相关。然而,这里的 namespace 更像是 GitLab 内部的逻辑概念(例如项目或组的命名空间),而不是操作系统级别的 namespace(如 Linux namespace 用于容器隔离)。因此,严格来说,这并不直接涉及操作系统级别的 namespace、cgroup、container 或容器隔离机制。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 根据描述,这个问题是关于 GitLab 的一个权限管理漏洞,允许被禁用的用户在某个命名空间级别访问 API。这主要是应用层面上的安全问题,与容器运行时的隔离性无关,也不会直接影响其他容器或宿主机。 3. **结论:** 条件 1 和条件 2 均不满足,因此返回: **N/A** cve: ./data/2023/1xxx/CVE-2023-1636.json A vulnerability was found in OpenStack Barbican containers.

IBM X-Force ID: 244500. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE提到了“creation of namespaces within a cluster”,明确涉及到了namespace的概念,而namespace是容器隔离机制中的一个核心组成部分。因此,该漏洞与namespace以及容器隔离相关。 2. **分析是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 该描述提到“insufficient security configuration which may allow creation of namespaces within a cluster”,即由于安全配置不足,可能允许在集群内创建新的namespace。如果攻击者能够利用此漏洞创建新的namespace,可能会绕过现有的隔离机制,从而对同一宿主机上的其他容器或宿主机本身造成潜在影响。因此,该漏洞有可能导致容器运行时影响其他容器或宿主机。 **结论**:该CVE满足条件1和条件2。 cve: ./data/2023/23xxx/CVE-2023-23586.json Due to a vulnerability in the io_uring subsystem, it is possible to leak kernel memory information to the user process. timens_install calls current_is_single_threaded to determine if the current process is single-threaded, but this call does not consider io_uring's io_worker threads, thus it is possible to insert a time namespace's vvar page to process's memory space via a page fault. When this time namespace is destroyed, the vvar page is also freed, but not removed from the process' memory, and a next page allocated by the kernel will be still available from the user-space process and can leak memory contents via this (read-only) use-after-free vulnerability. We recommend upgrading past version 5.10.161 or commit  788d0824269bef539fe31a785b1517882eafed93 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/io_uring analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该漏洞与 namespace 相关。具体来说,它涉及到时间命名空间(time namespace)。时间命名空间是 Linux 内核中的一种隔离机制,用于为不同的进程提供独立的时间视图。此漏洞利用了时间命名空间的 vvar 页面在进程内存中的处理不当,导致内核内存泄漏。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 是的,该漏洞可能会影响容器的隔离性。由于时间命名空间是容器隔离机制的一部分,此漏洞可能导致容器内的进程访问到宿主机或其他容器的敏感内核数据。这会破坏容器之间的隔离,并可能进一步被利用来攻击宿主机或其他容器。 3. **结论:** 条件 1 和条件 2 均满足,因此返回上述分析结果。 cve: ./data/2023/25xxx/CVE-2023-25173.json containerd is an open source container runtime. A bug was found in containerd prior to versions 1.6.18 and 1.5.18 where supplementary groups are not set up properly inside a container. If an attacker has direct access to a container and manipulates their supplementary group access, they may be able to use supplementary group access to bypass primary group restrictions in some cases, potentially gaining access to sensitive information or gaining the ability to execute code in that container. Downstream applications that use the containerd client library may be affected as well. This bug has been fixed in containerd v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue. Users who rely on a downstream application that uses containerd's client library should check that application for a separate advisory and instructions. As a workaround, ensure that the `"USER $USERNAME"` Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to `ENTRYPOINT ["su", "-", "user"]` to allow `su` to properly set up supplementary groups. analysis: ### 分析结果: 1. **是否与 namespace、cgroup、container 或容器、隔离相关:** 是的,该 CVE 与容器相关。具体来说,问题出现在 `containerd` 中,这是一个开源的容器运行时工具。问题涉及容器内的补充组(supplementary groups)设置不正确,这可能会影响容器内的权限管理。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 从描述来看,该漏洞的影响范围仅限于受影响的容器内部。攻击者可以通过操纵补充组访问权限来绕过某些限制,但没有提到可以突破容器隔离机制,进而影响其他容器或宿主机。因此,该漏洞不会直接影响其他容器或宿主机。 --- ### 最终结论: 满足条件 1,但不满足条件 2,因此返回以下分析: - **与容器相关:是** - **是否影响其他容器或宿主机:否** cve: ./data/2023/25xxx/CVE-2023-25809.json runc is a CLI tool for spawning and running containers according to the OCI specification. In affected versions it was found that rootless runc makes `/sys/fs/cgroup` writable in following conditons: 1. when runc is executed inside the user namespace, and the `config.json` does not specify the cgroup namespace to be unshared (e.g.., `(docker|podman|nerdctl) run --cgroupns=host`, with Rootless Docker/Podman/nerdctl) or 2. when runc is executed outside the user namespace, and `/sys` is mounted with `rbind, ro` (e.g., `runc spec --rootless`; this condition is very rare). A container may gain the write access to user-owned cgroup hierarchy `/sys/fs/cgroup/user.slice/...` on the host . Other users's cgroup hierarchies are not affected. Users are advised to upgrade to version 1.1.5. Users unable to upgrade may unshare the cgroup namespace (`(docker|podman|nerdctl) run --cgroupns=private)`. This is the default behavior of Docker/Podman/nerdctl on cgroup v2 hosts. or add `/sys/fs/cgroup` to `maskedPaths`. analysis: ### 分析结果: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关** 是的,该 CVE 信息明确提到了 `runc` 工具在处理容器时的问题,特别是与 cgroup 和用户命名空间(user namespace)相关的配置。问题的核心在于 rootless runc 在特定条件下使得 `/sys/fs/cgroup` 可写,这直接影响了 cgroup 的隔离性。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机** 是的,此漏洞可能导致容器获得对宿主机上用户拥有的 cgroup 层次结构(`/sys/fs/cgroup/user.slice/...`)的写访问权限。虽然其他用户的 cgroup 层次结构不受影响,但攻击者可能利用这一权限逃逸容器隔离环境,进而影响宿主机或其他依赖相同 cgroup 配置的容器。 3. **结论** 条件 1 和条件 2 均满足,因此返回以下分析内容: --- ### 漏洞分析总结: - **受影响组件**:`runc`(符合 OCI 规范的容器运行时工具)。 - **问题描述**:在特定条件下,rootless runc 会使宿主机上的 `/sys/fs/cgroup` 可写,从而破坏 cgroup 的隔离性。 - **影响范围**: - 容器可能获得对宿主机上用户拥有的 cgroup 层次结构的写访问权限。 - 这种访问权限可能会被滥用以突破容器隔离,影响宿主机或其他容器。 - **修复建议**: - 升级到 `runc` 版本 1.1.5。 - 如果无法升级,可以通过以下方式缓解: - 使用 `--cgroupns=private` 参数以单独隔离 cgroup 命名空间。 - 将 `/sys/fs/cgroup` 添加到 `maskedPaths` 中以屏蔽其访问。 此漏洞直接涉及容器隔离机制,需及时修复以避免潜在的安全风险。 cve: ./data/2023/26xxx/CVE-2023-26490.json mailcow is a dockerized email package, with multiple containers linked in one bridged network. The Sync Job feature - which can be made available to standard users by assigning them the necessary permission - suffers from a shell command injection. A malicious user can abuse this vulnerability to obtain shell access to the Docker container running dovecot. The imapsync Perl script implements all the necessary functionality for this feature, including the XOAUTH2 authentication mechanism. This code path creates a shell command to call openssl. However, since different parts of the specified user password are included without any validation, one can simply execute additional shell commands. Notably, the default ACL for a newly-created mailcow account does not include the necessary permission. The Issue has been fixed within the 2023-03 Update (March 3rd 2023). As a temporary workaround the Syncjob ACL can be removed from all mailbox users, preventing from creating or changing existing Syncjobs. analysis: 1. **是否与 namespace、cgroup、container 或容器、隔离相关:** 是的,该 CVE 与容器相关。具体来说,mailcow 是一个基于 Docker 的电子邮件解决方案,涉及多个容器通过桥接网络连接在一起。漏洞影响的是运行 dovecot 的 Docker 容器。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 从描述来看,此漏洞允许恶意用户通过 Sync Job 特性执行命令注入,从而获得对运行 dovecot 的容器的 shell 访问权限。然而,攻击范围被限制在该特定容器内,因为没有提到突破容器隔离机制(例如逃逸到宿主机或其他容器)。因此,此漏洞不会直接影响其他容器或宿主机,除非攻击者进一步利用其他漏洞实现容器逃逸。 **结论:** - 满足条件 1(与容器相关)。 - 不满足条件 2(不会直接影响其他容器或宿主机)。 cve: ./data/2023/27xxx/CVE-2023-27290.json Docker based datastores for IBM Instana (IBM Observability with Instana 239-0 through 239-2, 241-0 through 241-2, and 243-0) do not currently require authentication. Due to this, an attacker within the network could access the datastores with read/write access. IBM X-Force ID: 248737. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息与容器相关。问题描述中明确提到“Docker based datastores”,表明该漏洞涉及基于Docker的容器化数据存储。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 该漏洞描述指出,IBM Instana的数据存储未启用身份验证,导致攻击者可以在网络内获得对这些数据存储的读写访问权限。虽然此问题主要影响数据存储的安全性,但它并不直接涉及容器间的隔离机制或对宿主机的直接影响。然而,如果攻击者利用此漏洞修改或破坏共享数据存储的内容,可能会间接影响依赖该数据存储的其他容器或服务。 综上所述,该CVE与容器相关,并可能通过数据存储的滥用对其他容器产生间接影响,但不直接破坏容器隔离或直接影响宿主机。 cve: ./data/2023/27xxx/CVE-2023-27595.json Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In version 1.13.0, when Cilium is started, there is a short period when Cilium eBPF programs are not attached to the host. During this period, the host does not implement any of Cilium's featureset. This can cause disruption to newly established connections during this period due to the lack of Load Balancing, or can cause Network Policy bypass due to the lack of Network Policy enforcement during the window. This vulnerability impacts any Cilium-managed endpoints on the node (such as Kubernetes Pods), as well as the host network namespace (including Host Firewall). This vulnerability is fixed in Cilium 1.13.1 or later. Cilium releases 1.12.x, 1.11.x, and earlier are not affected. There are no known workarounds. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,此 CVE 与容器和隔离相关。Cilium 是一个用于容器网络和安全的解决方案,其主要功能是通过 eBPF 程序实现对容器(如 Kubernetes Pods)和主机网络命名空间的管理。漏洞描述中提到,在 Cilium 启动时,eBPF 程序未正确附加到主机,导致在此期间缺少网络策略强制执行和负载均衡功能。这直接影响了 Cilium 管理的端点(例如 Kubernetes Pods)以及主机网络命名空间。 2. **分析是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,此漏洞可能导致容器之间的隔离性被破坏。由于在 Cilium 启动期间缺乏网络策略强制执行,可能会导致网络策略绕过(Network Policy bypass),从而使某些容器能够访问本应被禁止的资源或网络。此外,主机网络命名空间也会受到影响,可能增加宿主机被攻击的风险。 因此,条件 1 和 2 都满足。 cve: ./data/2023/28xxx/CVE-2023-28840.json Moby is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component (`dockerd`), which is developed as moby/moby, is commonly referred to as *Docker*. Swarm Mode, which is compiled in and delivered by default in dockerd and is thus present in most major Moby downstreams, is a simple, built-in container orchestrator that is implemented through a combination of SwarmKit and supporting network code. The overlay network driver is a core feature of Swarm Mode, providing isolated virtual LANs that allow communication between containers and services across the cluster. This driver is an implementation/user of VXLAN, which encapsulates link-layer (Ethernet) frames in UDP datagrams that tag the frame with a VXLAN Network ID (VNI) that identifies the originating overlay network. In addition, the overlay network driver supports an optional, off-by-default encrypted mode, which is especially useful when VXLAN packets traverses an untrusted network between nodes. Encrypted overlay networks function by encapsulating the VXLAN datagrams through the use of the IPsec Encapsulating Security Payload protocol in Transport mode. By deploying IPSec encapsulation, encrypted overlay networks gain the additional properties of source authentication through cryptographic proof, data integrity through check-summing, and confidentiality through encryption. When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the u32 iptables extension provided by the xt_u32 kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN. Two iptables rules serve to filter incoming VXLAN datagrams with a VNI that corresponds to an encrypted network and discards unencrypted datagrams. The rules are appended to the end of the INPUT filter chain, following any rules that have been previously set by the system administrator. Administrator-set rules take precedence over the rules Moby sets to discard unencrypted VXLAN datagrams, which can potentially admit unencrypted datagrams that should have been discarded. The injection of arbitrary Ethernet frames can enable a Denial of Service attack. A sophisticated attacker may be able to establish a UDP or TCP connection by way of the container’s outbound gateway that would otherwise be blocked by a stateful firewall, or carry out other escalations beyond simple injection by smuggling packets into the overlay network. Patches are available in Moby releases 23.0.3 and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16. Some workarounds are available. Close the VXLAN port (by default, UDP port 4789) to incoming traffic at the Internet boundary to prevent all VXLAN packet injection, and/or ensure that the `xt_u32` kernel module is available on all nodes of the Swarm cluster. analysis: ### 分析结果: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,此 CVE 与容器和隔离相关。具体来说,它涉及 Docker 的 Swarm Mode 和 overlay 网络驱动,这是用于在容器集群中提供网络隔离的核心功能之一。问题出在 iptables 规则配置上,这些规则旨在确保加密的 overlay 网络流量不会被未加密的流量干扰,从而影响网络隔离。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机:** 是的,该漏洞可能导致未加密的 VXLAN 数据包绕过预期的安全检查,进入加密的 overlay 网络。这可能会导致以下后果: - 攻击者可以通过注入任意以太网帧来发起拒绝服务 (DoS) 攻击。 - 高级攻击者可能利用此漏洞建立本应被防火墙阻止的 UDP 或 TCP 连接。 - 这种行为可能破坏容器之间的网络隔离,甚至可能影响宿主机的安全性。 ### 结论: 满足条件 1 和 2,因此返回分析内容。 cve: ./data/2023/28xxx/CVE-2023-28841.json Moby is an open source container framework developed by Docker Inc. that is distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products.

An iptables rule designates outgoing VXLAN datagrams with a VNI that corresponds to an encrypted overlay network for IPsec encapsulation. Encrypted overlay networks on affected platforms silently transmit unencrypted data. As a result, `overlay` networks may appear to be functional, passing traffic as expected, but without any of the expected confidentiality or data integrity guarantees. It is possible for an attacker sitting in a trusted position on the network to read all of the application traffic that is moving across the overlay network, resulting in unexpected secrets or user data disclosure. Thus, because many database protocols, internal APIs, etc. are not protected by a second layer of encryption, a user may use Swarm encrypted overlay networks to provide confidentiality, which due to this vulnerability this is no longer guaranteed. Patches are available in Moby releases 23.0.3, and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16.

When setting an endpoint up on an encrypted overlay network, Moby installs three iptables (Linux kernel firewall) rules that enforce both incoming and outgoing IPSec. These rules rely on the `u32` iptables extension provided by the `xt_u32` kernel module to directly filter on a VXLAN packet's VNI field, so that IPSec guarantees can be enforced on encrypted overlay networks without interfering with other overlay networks or other users of VXLAN. The `overlay` driver dynamically and lazily defines the kernel configuration for the VXLAN network on each node as containers are attached and detached. Routes and encryption parameters are only defined for destination nodes that participate in the network. The iptables rules that prevent encrypted overlay networks from accepting unencrypted packets are not created until a peer is available with which to communicate. Encrypted overlay networks silently accept cleartext VXLAN datagrams that are tagged with the VNI of an encrypted overlay network. As a result, it is possible to inject arbitrary Ethernet frames into the encrypted overlay network by encapsulating them in VXLAN datagrams. The implications of this can be quite dire, and GHSA-vwm3-crmr-xfxw should be referenced for a deeper exploration. Patches are available in Moby releases 23.0.3, and 20.10.24. As Mirantis Container Runtime's 20.10 releases are numbered differently, users of that platform should update to 20.10.16. Some workarounds are available. In multi-node clusters, deploy a global ‘pause’ container for each encrypted overlay network, on every node. For a single-node cluster, do not use overlay networks of any sort. Bridge networks provide the same connectivity on a single node and have no multi-node features. The Swarm ingress feature is implemented using an overlay network, but can be disabled by publishing ports in `host` mode instead of `ingress` mode (allowing the use of an external load balancer), and removing the `ingress` network. If encrypted overlay networks are in exclusive use, block UDP port 4789 from traffic that has not been validated by IPSec. analysis: ### 分析结果: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** - 是。该 CVE 涉及 Moby(Docker 的核心组件)中的 `overlay` 网络驱动,这是一个用于容器间通信的核心功能。`overlay` 网络通过 VXLAN 提供跨节点的容器网络隔离。此外,加密的 overlay 网络依赖于 iptables 规则和 IPsec 来确保数据的机密性和完整性,这直接影响容器之间的网络隔离。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** - 是。由于加密的 overlay 网络会错误地接受未加密的 VXLAN 数据包,攻击者可以通过注入任意以太网帧来破坏网络隔离。这种漏洞可能允许攻击者从一个容器中发送恶意流量到另一个容器或宿主机,从而突破容器间的隔离,甚至可能对宿主机或其他容器造成进一步的危害。 ### 结论: 该 CVE 信息满足条件 1 和条件 2,因此分析表明它与容器隔离相关,并可能导致容器运行时影响其他容器或宿主机。 cve: ./data/2023/28xxx/CVE-2023-28960.json An Incorrect Permission Assignment for Critical Resource vulnerability in Juniper Networks Junos OS Evolved allows a local, authenticated low-privileged attacker to copy potentially malicious files into an existing Docker container on the local system. A follow-on administrator could then inadvertently start the Docker container leading to the malicious files being executed as root. This issue only affects systems with Docker configured and enabled, which is not enabled by default. Systems without Docker started are not vulnerable to this issue. This issue affects Juniper Networks Junos OS Evolved: 20.4 versions prior to 20.4R3-S5-EVO; 21.2 versions prior to 21.2R3-EVO; 21.3 versions prior to 21.3R3-EVO; 21.4 versions prior to 21.4R2-EVO. This issue does not affect Juniper Networks Junos OS Evolved versions prior to 19.2R1-EVO. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息明确提到与Docker容器相关。攻击者可以通过权限分配错误将恶意文件复制到现有的Docker容器中,这表明问题与容器的文件系统和资源隔离机制有关。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器内的恶意文件被执行,并且以root权限运行。如果容器共享了宿主机的某些资源(例如通过不恰当的配置),这种行为可能会进一步影响宿主机或其他容器的安全性。此外,攻击需要本地低权限用户发起,说明容器环境可能存在权限管理或隔离上的缺陷。 因此,根据分析,该CVE满足条件1和条件2。 cve: ./data/2023/29xxx/CVE-2023-29002.json Cilium is a networking, observability, and security solution with an eBPF-based dataplane. When run in debug mode, Cilium will log the contents of the `cilium-secrets` namespace. This could include data such as TLS private keys for Ingress and GatewayAPI resources. An attacker with access to debug output from the Cilium containers could use the resulting output to intercept and modify traffic to and from the affected cluster. Output of the sensitive information would occur at Cilium agent restart, when secrets in the namespace are modified, and on creation of Ingress or GatewayAPI resources. This vulnerability is fixed in Cilium releases 1.11.16, 1.12.9, and 1.13.2. Users unable to upgrade should disable debug mode. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 相关。具体来说,Cilium 在调试模式下会记录 `cilium-secrets` 命名空间的内容,这可能包含敏感数据(例如 TLS 私钥)。命名空间是 Linux 容器隔离机制的一部分,因此这里涉及到了 namespace 的概念。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 这个漏洞本身不会直接导致容器影响其他容器或宿主机。然而,如果攻击者能够访问调试输出(例如通过获取 Cilium 容器的日志),他们可以利用泄露的敏感信息(如 TLS 私钥)来拦截和修改流量,从而对整个集群的安全性造成威胁。这种威胁主要体现在数据泄露和潜在的流量操控上,而不是直接破坏容器隔离或宿主机安全。 3. **结论:** 条件 1 满足(与 namespace 相关),条件 2 不完全满足(不会直接影响其他容器或宿主机,但可能导致间接威胁)。因此,返回分析结果而非 "N/A"。 cve: ./data/2023/30xxx/CVE-2023-30549.json Apptainer is an open source container platform for Linux. There is an ext4 use-after-free flaw that is exploitable through versions of Apptainer < 1.1.0 and installations that include apptainer-suid < 1.1.8 on older operating systems where that CVE has not been patched. That includes Red Hat Enterprise Linux 7, Debian 10 buster (unless the linux-5.10 package is installed), Ubuntu 18.04 bionic and Ubuntu 20.04 focal. Use-after-free flaws in the kernel can be used to attack the kernel for denial of service and potentially for privilege escalation. Apptainer 1.1.8 includes a patch that by default disables mounting of extfs filesystem types in setuid-root mode, while continuing to allow mounting of extfs filesystems in non-setuid "rootless" mode using fuse2fs. Some workarounds are possible. Either do not install apptainer-suid (for versions 1.1.0 through 1.1.7) or set `allow setuid = no` in apptainer.conf. This requires having unprivileged user namespaces enabled and except for apptainer 1.1.x versions will disallow mounting of sif files, extfs files, and squashfs files in addition to other, less significant impacts. (Encrypted sif files are also not supported unprivileged in apptainer 1.1.x.). Alternatively, use the `limit containers` options in apptainer.conf/singularity.conf to limit sif files to trusted users, groups, and/or paths, and set `allow container extfs = no` to disallow mounting of extfs overlay files. The latter option by itself does not disallow mounting of extfs overlay partitions inside SIF files, so that's why the former options are also needed. analysis: ### 分析结果: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与容器技术相关。Apptainer(前身为 Singularity)是一个开源的容器平台,用于在 Linux 系统上运行容器化应用程序。此漏洞涉及 Apptainer 的文件系统挂载功能,特别是在使用 setuid-root 模式时挂载 extfs 文件系统时可能存在 use-after-free 漏洞。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 是的,此漏洞可能会影响宿主机的安全性。具体来说,use-after-free 漏洞可以被利用来攻击内核,导致拒绝服务(DoS)或潜在的权限提升(privilege escalation)。由于 Apptainer 的设计允许容器直接与宿主机内核交互(特别是在 setuid-root 模式下),这种漏洞可能会波及宿主机或其他容器。 3. **结论:** 条件 1 和条件 2 均满足,因此返回分析结果而非 "N/A"。 cve: ./data/2023/30xxx/CVE-2023-30840.json Fluid is an open source Kubernetes-native distributed dataset orchestrator and accelerator for data-intensive applications. Starting in version 0.7.0 and prior to version 0.8.6, if a malicious user gains control of a Kubernetes node running fluid csi pod (controlled by the `csi-nodeplugin-fluid` node-daemonset), they can leverage the fluid-csi service account to modify specs of all the nodes in the cluster. However, since this service account lacks `list node` permissions, the attacker may need to use other techniques to identify vulnerable nodes. Once the attacker identifies and modifies the node specs, they can manipulate system-level-privileged components to access all secrets in the cluster or execute pods on other nodes. This allows them to elevate privileges beyond the compromised node and potentially gain full privileged access to the whole cluster. To exploit this vulnerability, the attacker can make all other nodes unschedulable (for example, patch node with taints) and wait for system-critical components with high privilege to appear on the compromised node. However, this attack requires two prerequisites: a compromised node and identifying all vulnerable nodes through other means. Version 0.8.6 contains a patch for this issue. As a workaround, delete the `csi-nodeplugin-fluid` daemonset in `fluid-system` namespace and avoid using CSI mode to mount FUSE file systems. Alternatively, using sidecar mode to mount FUSE file systems is recommended. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞与容器和Kubernetes集群中的隔离性相关。具体来说,Fluid 是一个 Kubernetes 原生的分布式数据集编排和加速工具,涉及 CSI(Container Storage Interface)插件的使用。漏洞描述中提到,攻击者可以通过控制 `csi-nodeplugin-fluid` 的 DaemonSet,利用 Fluid 的 CSI 服务账户权限来修改节点规格,从而影响整个集群的资源调度和安全性。这表明该问题与容器运行时环境及 Kubernetes 集群的隔离机制密切相关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致攻击者突破单个节点的限制,影响其他节点上的容器或宿主机的安全性。通过修改节点规格,攻击者可以操控系统级特权组件,访问集群中的所有机密信息,甚至在其他节点上执行恶意 Pod。这表明该漏洞可能破坏容器之间的隔离性,并对整个集群构成威胁。 3. **结论**: 条件 1 和条件 2 均满足,因此需要返回分析结果。 cve: ./data/2023/30xxx/CVE-2023-30997.json IBM Security Access Manager Docker 10.0.0.0 through 10.0.7.1 could allow a local user to obtain root access due to improper access controls.

As a workaround, restrict the creation of `ReferenceGrant` resources to admin users by using Kubernetes RBAC. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 相关。问题的核心在于 Cilium 在处理 Gateway API 时,未对 ReferenceGrant 所在的 namespace 进行检查,从而导致跨 namespace 的秘密(如证书和服务)被无意中暴露。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 该漏洞可能会间接影响其他容器的安全性。由于 Cilium 是一个网络和安全解决方案,负责管理容器之间的网络通信和访问控制,因此如果攻击者利用此漏洞获取了不应访问的秘密或服务,他们可能能够绕过隔离机制,进而影响其他容器或宿主机的安全。 **结论:** 满足条件 1 和 2,因此返回上述分析内容。 cve: ./data/2023/34xxx/CVE-2023-34844.json Play With Docker < 0.0.2 has an insecure CAP_SYS_ADMIN privileged mode causing the docker container to escape. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器和隔离相关。描述中提到 Docker 容器的特权模式 (`CAP_SYS_ADMIN`) 存在安全问题,可能导致容器逃逸。容器逃逸通常涉及破坏容器与宿主机之间的隔离机制,因此直接关联到容器隔离技术(如 namespace 和 cgroup)。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该 CVE 可能导致容器逃逸,从而使攻击者能够影响宿主机或其他在相同宿主机上运行的容器。具体来说,`CAP_SYS_ADMIN` 特权模式的不安全实现可能允许攻击者突破容器的限制,访问宿主机资源或干扰其他容器的正常运行。 **结论**:满足条件 1 和 2。 cve: ./data/2023/35xxx/CVE-2023-35001.json Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace analysis: 1. **是否与 namespace、cgroup、container 或容器、隔离相关:** 是的,该 CVE 信息与 namespace 相关。描述中提到 "CAP_NET_ADMIN is in any user or network namespace",说明问题涉及网络命名空间和用户命名空间,这些是 Linux 容器(如 Docker)实现隔离的重要组成部分。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 可能会。由于该漏洞涉及 `nftables` 的出界读写问题,并且与 `CAP_NET_ADMIN` 权限在命名空间中的处理有关,攻击者可能利用此漏洞突破容器的隔离,影响其他容器或宿主机的安全性。具体影响取决于容器配置以及是否赋予了相关权限。 **结论:满足条件 1 和 2,需注意此漏洞对容器环境的潜在威胁。** cve: ./data/2023/37xxx/CVE-2023-37273.json Auto-GPT is an experimental open-source application showcasing the capabilities of the GPT-4 language model. Running Auto-GPT version prior to 0.4.3 by cloning the git repo and executing `docker compose run auto-gpt` in the repo root uses a different docker-compose.yml file from the one suggested in the official docker set up instructions. The docker-compose.yml file located in the repo root mounts itself into the docker container without write protection. This means that if malicious custom python code is executed via the `execute_python_file` and `execute_python_code` commands, it can overwrite the docker-compose.yml file and abuse it to gain control of the host system the next time Auto-GPT is started. The issue has been patched in version 0.4.3. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,此 CVE 信息与容器和隔离相关。问题涉及 Docker 容器中 `docker-compose.yml` 文件被错误地挂载到容器内,并且没有启用写保护。这破坏了容器应有的隔离性,使得恶意代码可以在容器内修改宿主机上的文件。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 是的,此漏洞可能导致容器内的恶意代码覆盖宿主机上的 `docker-compose.yml` 文件。当宿主机下次启动 Auto-GPT 时,攻击者可以通过篡改后的配置文件进一步控制宿主机系统,从而对其他容器或整个宿主机造成威胁。 3. **结论**: 条件 1 和条件 2 均满足,因此需要返回上述分析内容。 cve: ./data/2023/37xxx/CVE-2023-37274.json Auto-GPT is an experimental open-source application showcasing the capabilities of the GPT-4 language model. When Auto-GPT is executed directly on the host system via the provided run.sh or run.bat files, custom Python code execution is sandboxed using a temporary dedicated docker container which should not have access to any files outside of the Auto-GPT workspace directory. Before v0.4.3, the `execute_python_code` command (introduced in v0.4.1) does not sanitize the `basename` arg before writing LLM-supplied code to a file with an LLM-supplied name. This allows for a path traversal attack that can overwrite any .py file outside the workspace directory by specifying a `basename` such as `../../../main.py`. This can further be abused to achieve arbitrary code execution on the host running Auto-GPT by e.g. overwriting autogpt/main.py which will be executed outside of the docker environment meant to sandbox custom python code execution the next time Auto-GPT is started. The issue has been patched in version 0.4.3. As a workaround, the risk introduced by this vulnerability can be remediated by running Auto-GPT in a virtual machine, or another environment in which damage to files or corruption of the program is not a critical problem. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 信息与容器和隔离相关。Auto-GPT 使用了一个临时的专用 Docker 容器来沙箱化自定义 Python 代码的执行,以确保其不会访问 Auto-GPT 工作区目录之外的任何文件。然而,由于 `execute_python_code` 命令未对 `basename` 参数进行适当的 sanitization(清理),导致路径遍历攻击可以绕过这种隔离机制,从而影响宿主机上的文件。 2. **分析是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器内的操作影响宿主机。通过路径遍历攻击,攻击者可以覆盖宿主机上的关键文件(例如 `autogpt/main.py`),并在宿主机上实现任意代码执行。这种行为破坏了容器的隔离性,使得容器内的漏洞能够直接影响宿主机,进而可能间接影响同一宿主机上的其他容器。 3. **结论**: 由于条件 1 和条件 2 都满足,因此返回上述分析内容。 cve: ./data/2023/39xxx/CVE-2023-39347.json Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to update pod labels can cause Cilium to apply incorrect network policies. This issue arises due to the fact that on pod update, Cilium incorrectly uses user-provided pod labels to select the policies which apply to the workload in question. This can affect Cilium network policies that use the namespace, service account or cluster constructs to restrict traffic, Cilium clusterwide network policies that use Cilium namespace labels to select the Pod and Kubernetes network policies. Non-existent construct names can be provided, which bypass all network policies applicable to the construct. For example, providing a pod with a non-existent namespace as the value of the `io.kubernetes.pod.namespace` label results in none of the namespaced CiliumNetworkPolicies applying to the pod in question. This attack requires the attacker to have Kubernetes API Server access, as described in the Cilium Threat Model. This issue has been resolved in: Cilium versions 1.14.2, 1.13.7, and 1.12.14. Users are advised to upgrade. As a workaround an admission webhook can be used to prevent pod label updates to the `k8s:io.kubernetes.pod.namespace` and `io.cilium.k8s.policy.*` keys. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 和容器隔离相关。问题的核心在于 Cilium 在处理 pod 更新时,错误地使用了用户提供的 pod 标签(labels),这可能导致不正确的网络策略被应用到特定的工作负载上。特别是,当提供一个不存在的命名空间(namespace)标签时,所有与该命名空间相关的 Cilium 网络策略将不再生效。因此,这直接影响了基于命名空间的隔离机制。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 是的,此漏洞可能会影响容器之间的隔离性。通过利用该漏洞,攻击者可以绕过网络策略,导致本应隔离的容器之间能够进行未授权的通信。虽然该漏洞本身不会直接破坏宿主机的安全性,但它可能会间接削弱容器之间的隔离,从而为攻击者提供进一步渗透的机会。 **结论:** 该 CVE 满足条件 1 和条件 2,因此需要进行上述分析。 cve: ./data/2023/39xxx/CVE-2023-39523.json ScanCode.io is a server to script and automate software composition analysis with ScanPipe pipelines. Prior to version 32.5.1, the software has a possible command injection vulnerability in the docker fetch process as it allows to append malicious commands in the `docker_reference` parameter. In the function `scanpipe/pipes/fetch.py:fetch_docker_image` the parameter `docker_reference` is user controllable. The `docker_reference` variable is then passed to the vulnerable function `get_docker_image_platform`. However, the `get_docker_image_plaform` function constructs a shell command with the passed `docker_reference`. The `pipes.run_command` then executes the shell command without any prior sanitization, making the function vulnerable to command injections. A malicious user who is able to create or add inputs to a project can inject commands. Although the command injections are blind and the user will not receive direct feedback without logs, it is still possible to cause damage to the server/container. The vulnerability appears for example if a malicious user adds a semicolon after the input of `docker://;`, it would allow appending malicious commands. Version 32.5.1 contains a patch for this issue. The `docker_reference` input should be sanitized to avoid command injections and, as a workaround, one may avoid creating commands with user controlled input directly. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,此漏洞与容器相关。漏洞出现在 `ScanCode.io` 的 `docker fetch` 过程中,涉及 `docker_reference` 参数的处理。该参数被传递到一个函数中,最终用于构造并执行 shell 命令,而这些命令可能在容器环境中运行。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 是的,此漏洞可能导致容器运行时影响宿主机或其他容器。由于命令注入漏洞的存在,攻击者可以通过恶意构造的 `docker_reference` 参数执行任意命令。如果容器以特权模式运行或共享宿主机的资源(如文件系统、网络等),攻击者可以利用此漏洞对宿主机或其他容器造成损害。 3. **结论**: 条件 1 和条件 2 均满足,因此返回分析结果。 cve: ./data/2023/3xxx/CVE-2023-3027.json The grc-policy-propagator allows security escalation within the cluster.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 描述中提到 Docker Machine 的版本数据处理问题,可能通过逃逸序列注入或数据大小导致拒绝服务。这与容器的运行时行为有关,但并未直接涉及 namespace、cgroup 或隔离机制的具体实现。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 根据描述,攻击者可以通过控制 worker 节点提供恶意版本数据,从而可能影响 bastion 节点。这种影响可能间接导致管理员执行不安全操作,或者通过大尺寸数据引发拒绝服务。虽然没有明确提到容器逃逸,但 bastion 节点可能与宿主机或其他容器共享资源,因此存在潜在影响宿主机或间接影响其他容器的风险。 3. **结论**: 条件 1 和条件 2 部分满足,因此返回以下分析: - 与容器相关,但未直接涉及 namespace 或 cgroup。 - 存在通过恶意输入影响宿主机或其他容器的潜在风险。 cve: ./data/2023/41xxx/CVE-2023-41333.json Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to create or modify CiliumNetworkPolicy objects in a particular namespace is able to affect traffic on an entire Cilium cluster, potentially bypassing policy enforcement in other namespaces. By using a crafted `endpointSelector` that uses the `DoesNotExist` operator on the `reserved:init` label, the attacker can create policies that bypass namespace restrictions and affect the entire Cilium cluster. This includes potentially allowing or denying all traffic. This attack requires API server access, as described in the Kubernetes API Server Attacker section of the Cilium Threat Model. This issue has been resolved in Cilium versions 1.14.2, 1.13.7, and 1.12.14. As a workaround an admission webhook can be used to prevent the use of `endpointSelectors` that use the `DoesNotExist` operator on the `reserved:init` label in CiliumNetworkPolicies. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,这个 CVE 信息与 namespace 和容器隔离相关。问题的核心在于攻击者可以通过修改 CiliumNetworkPolicy 对象,利用特定的 `endpointSelector` 规则(如 `DoesNotExist` 操作符作用于 `reserved:init` 标签),绕过 namespace 的限制,从而影响整个 Cilium 集群的网络策略执行。这表明该漏洞破坏了 namespace 级别的隔离性。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 这个 CVE 主要影响的是 Cilium 网络策略的执行,而不是直接对容器或宿主机的安全性造成威胁。然而,由于攻击者可以绕过 namespace 的限制并影响整个集群的流量规则,可能会间接导致某些容器之间的通信被错误地允许或拒绝。虽然这不是直接的容器逃逸漏洞,但它确实可能削弱容器间的网络隔离,进而对容器环境的整体安全性产生负面影响。 因此,根据以上分析,结论如下: - 该 CVE 与 namespace 和容器隔离相关。 - 它不会直接导致容器逃逸,但会削弱容器间的网络隔离,可能间接影响其他容器或宿主机的安全性。 **最终答案:满足条件 1 和 2 的部分要求,非 N/A。** cve: ./data/2023/42xxx/CVE-2023-42125.json Avast Premium Security Sandbox Protection Link Following Privilege Escalation Vulnerability.

The specific flaw exists within the implementation of the sandbox feature. By creating a symbolic link, an attacker can abuse the service to create arbitrary namespace objects. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. . Was ZDI-CAN-20383. analysis: 1. 该 CVE 信息与 namespace 相关,因为描述中提到攻击者可以通过创建符号链接滥用服务来创建任意的 namespace 对象。 2. 该 CVE 不直接影响容器(如 Docker)或其隔离机制。虽然提到了 namespace,但此漏洞是特定于 Avast Premium Security 的沙箱功能实现问题,而不是容器运行时或 cgroup、container 隔离相关的通用问题。因此,它不会导致容器影响其他容器或宿主机。 3. 综上所述,条件 1 满足(与 namespace 相关),但条件 2 不满足(不影响容器或其他容器/宿主机的隔离)。 **分析结果:** - 与 namespace 相关。 - 不会影响容器或宿主机的隔离。 cve: ./data/2023/48xxx/CVE-2023-48225.json Laf is a cloud development platform. Prior to version 1.0.0-beta.13, the control of LAF app enV is not strict enough, and in certain scenarios of privatization environment, it may lead to sensitive information leakage in secret and configmap. In ES6 syntax, if an obj directly references another obj, the name of the obj itself will be used as the key, and the entire object structure will be integrated intact. When constructing the deployment instance of the app, env was found from the database and directly inserted into the template, resulting in controllability here. Sensitive information in the secret and configmap can be read through the k8s envFrom field. In a privatization environment, when `namespaceConf. fixed` is marked, it may lead to the leakage of sensitive information in the system. As of time of publication, it is unclear whether any patches or workarounds exist. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 和容器相关。描述中提到在 Kubernetes 环境下,通过 `envFrom` 字段可能导致敏感信息泄漏,而 `namespaceConf.fixed` 的配置也表明了问题涉及 Kubernetes 的命名空间(namespace)管理。Kubernetes 是一个容器编排平台,因此该问题间接与容器和隔离机制相关。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 是的,可能存在影响。由于问题涉及 Kubernetes 的环境变量注入(`envFrom`),如果敏感信息(如 secrets 和 configmaps)被泄漏,攻击者可能利用这些信息访问其他容器或宿主机资源,特别是在共享同一命名空间的场景下。虽然该漏洞本身并不直接破坏容器隔离,但泄漏的敏感信息可能会被滥用,从而间接影响其他容器或宿主机的安全。 **结论:** 满足条件 1 和 2,分析完毕。 cve: ./data/2023/48xxx/CVE-2023-48311.json dockerspawner is a tool to spawn JupyterHub single user servers in Docker containers. Users of JupyterHub deployments running DockerSpawner starting with 0.11.0 without specifying `DockerSpawner.allowed_images` configuration allow users to launch _any_ pullable docker image, instead of restricting to only the single configured image, as intended. This issue has been addressed in commit `3ba4b665b` which has been included in dockerspawner release version 13. Users are advised to upgrade. Users unable to upgrade should explicitly set `DockerSpawner.allowed_images` to a non-empty list containing only the default image will result in the intended default behavior. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 信息与容器相关。`dockerspawner` 是一个用于在 Docker 容器中启动 JupyterHub 单用户服务器的工具,涉及容器的配置和使用。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 该漏洞允许用户启动任意可拉取的 Docker 镜像,而不是限制为单个配置的镜像。这可能会导致以下风险: - 用户可以启动具有更高权限或恶意行为的容器。 - 恶意容器可能尝试逃逸或利用其他漏洞来影响宿主机或其他容器。 - 如果没有适当的隔离配置(如 namespace 或 cgroup),这种行为可能会对宿主机的安全性造成威胁。 因此,该漏洞可能会影响其他容器或宿主机的安全性。 **结论**:满足条件 1 和 2。 cve: ./data/2023/49xxx/CVE-2023-49103.json An issue was discovered in ownCloud owncloud/graphapi 0.2.x before 0.2.1 and 0.3.x before 0.3.1. The graphapi app relies on a third-party GetPhpInfo.php library that provides a URL. When this URL is accessed, it reveals the configuration details of the PHP environment (phpinfo). This information includes all the environment variables of the webserver. In containerized deployments, these environment variables may include sensitive data such as the ownCloud admin password, mail server credentials, and license key. Simply disabling the graphapi app does not eliminate the vulnerability. Additionally, phpinfo exposes various other potentially sensitive configuration details that could be exploited by an attacker to gather information about the system. Therefore, even if ownCloud is not running in a containerized environment, this vulnerability should still be a cause for concern. Note that Docker containers from before February 2023 are not vulnerable to the credential disclosure. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 提到在容器化部署中,环境变量可能包含敏感信息(例如 ownCloud 管理员密码、邮件服务器凭据和许可证密钥)。这表明它与容器化环境相关,尤其是涉及容器内部的环境变量暴露问题。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 从描述来看,此漏洞主要导致敏感信息泄露,而不是直接破坏容器隔离性或影响其他容器或宿主机。然而,泄露的敏感信息(如管理员密码、邮件服务器凭据等)可能会被攻击者利用,间接对系统造成进一步威胁。虽然 Docker 容器在 2023 年 2 月之前的版本不受凭据泄露影响,但信息泄露本身仍然是一个严重问题。 **结论:** - 该 CVE 与容器化环境相关,尤其是涉及容器内的环境变量暴露。 - 虽然不会直接破坏容器隔离性或直接影响其他容器或宿主机,但泄露的信息可能被用于进一步攻击。 cve: ./data/2023/50xxx/CVE-2023-50253.json Laf is a cloud development platform. In the Laf version design, the log uses communication with k8s to quickly retrieve logs from the container without the need for additional storage. However, in version 1.0.0-beta.13 and prior, this interface does not verify the permissions of the pod, which allows authenticated users to obtain any pod logs under the same namespace through this method, thereby obtaining sensitive information printed in the logs. As of time of publication, no known patched versions exist. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 和容器相关。问题描述中提到通过未验证权限的接口可以获取同一 namespace 下的任何 pod 日志,这表明问题发生在 Kubernetes 的 namespace 范围内,并且涉及容器日志的访问。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 不会直接影响其他容器或宿主机。虽然攻击者可以通过此漏洞获取同一 namespace 下其他 pod 的日志,但并未提到此漏洞允许直接访问其他容器的资源或宿主机系统。因此,影响主要集中在日志中的敏感信息泄露,而不是对容器或宿主机的进一步控制。 **结论:** - 满足条件 1,与 namespace 和容器相关。 - 不满足条件 2,不会直接影响其他容器或宿主机。 cve: ./data/2023/52xxx/CVE-2023-52707.json In the Linux kernel, the following vulnerability has been resolved: sched/psi: Fix use-after-free in ep_remove_wait_queue() If a non-root cgroup gets removed when there is a thread that registered trigger and is polling on a pressure file within the cgroup, the polling waitqueue gets freed in the following path: do_rmdir cgroup_rmdir kernfs_drain_open_files cgroup_file_release cgroup_pressure_release psi_trigger_destroy However, the polling thread still has a reference to the pressure file and will access the freed waitqueue when the file is closed or upon exit: fput ep_eventpoll_release ep_free ep_remove_wait_queue remove_wait_queue This results in use-after-free as pasted below. The fundamental problem here is that cgroup_file_release() (and consequently waitqueue's lifetime) is not tied to the file's real lifetime. Using wake_up_pollfree() here might be less than ideal, but it is in line with the comment at commit 42288cb44c4b ("wait: add wake_up_pollfree()") since the waitqueue's lifetime is not tied to file's one and can be considered as another special case. While this would be fixable by somehow making cgroup_file_release() be tied to the fput(), it would require sizable refactoring at cgroups or higher layer which might be more justifiable if we identify more cases like this.

As a result, it is possible to leave parent with no effective cpu left even if there are tasks in the parent cpuset. This can lead to system panic as reported in [1]. Fix this probem by updating the check to fail the enabling the partition if parent's effective_cpus is a subset of the child's cpus_allowed. Also record the error code when an error happens in update_prstate() and add a test case where parent partition and child have the same cpu list and parent has task. Enabling partition in the child will fail in this case. [1] https://www.spinics.net/lists/cgroups/msg36254.html analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE与cgroup(控制组)直接相关。具体来说,问题出现在`cpuset`子系统中的`update_parent_subparts_cpumask()`函数中,涉及对CPU资源分配的检查逻辑。 2. **是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器运行时影响宿主机或其他容器的稳定性。由于`cpuset`子系统用于限制和分配CPU资源,错误的检查逻辑可能使得父`cpuset`(通常对应宿主机或其他共享资源的容器)被剥夺所有可用CPU资源,从而导致任务无法正常运行,甚至引发系统崩溃(如描述中提到的“system panic”)。 因此,该CVE满足条件1和条件2。 cve: ./data/2023/5xxx/CVE-2023-5056.json A flaw was found in the Skupper operator, which may permit a certain configuration to create a service account that would allow an authenticated attacker in the adjacent cluster to view deployments in all namespaces in the cluster.

Moby's networking implementation allows for many networks, each with their own IP address range and gateway, to be defined. This feature is frequently referred to as custom networks, as each network can have a different driver, set of parameters and thus behaviors. When creating a network, the `--internal` flag is used to designate a network as _internal_. The `internal` attribute in a docker-compose.yml file may also be used to mark a network _internal_, and other API clients may specify the `internal` parameter as well. When containers with networking are created, they are assigned unique network interfaces and IP addresses. The host serves as a router for non-internal networks, with a gateway IP that provides SNAT/DNAT to/from container IPs. Containers on an internal network may communicate between each other, but are precluded from communicating with any networks the host has access to (LAN or WAN) as no default route is configured, and firewall rules are set up to drop all outgoing traffic. Communication with the gateway IP address (and thus appropriately configured host services) is possible, and the host may communicate with any container IP directly. In addition to configuring the Linux kernel's various networking features to enable container networking, `dockerd` directly provides some services to container networks. Principal among these is serving as a resolver, enabling service discovery, and resolution of names from an upstream resolver. When a DNS request for a name that does not correspond to a container is received, the request is forwarded to the configured upstream resolver. This request is made from the container's network namespace: the level of access and routing of traffic is the same as if the request was made by the container itself. As a consequence of this design, containers solely attached to an internal network will be unable to resolve names using the upstream resolver, as the container itself is unable to communicate with that nameserver. Only the names of containers also attached to the internal network are able to be resolved. Many systems run a local forwarding DNS resolver. As the host and any containers have separate loopback devices, a consequence of the design described above is that containers are unable to resolve names from the host's configured resolver, as they cannot reach these addresses on the host loopback device. To bridge this gap, and to allow containers to properly resolve names even when a local forwarding resolver is used on a loopback address, `dockerd` detects this scenario and instead forward DNS requests from the host namework namespace. The loopback resolver then forwards the requests to its configured upstream resolvers, as expected. Because `dockerd` forwards DNS requests to the host loopback device, bypassing the container network namespace's normal routing semantics entirely, internal networks can unexpectedly forward DNS requests to an external nameserver. By registering a domain for which they control the authoritative nameservers, an attacker could arrange for a compromised container to exfiltrate data by encoding it in DNS queries that will eventually be answered by their nameservers. Docker Desktop is not affected, as Docker Desktop always runs an internal resolver on a RFC 1918 address. Moby releases 26.0.0, 25.0.4, and 23.0.11 are patched to prevent forwarding any DNS requests from internal networks. As a workaround, run containers intended to be solely attached to internal networks with a custom upstream address, which will force all upstream DNS queries to be resolved from the container's network namespace. analysis: ### 分析结果 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与容器和隔离相关。具体来说,问题涉及 Moby(Docker 的核心组件)在处理内部网络(`--internal` 网络)时的行为。`dockerd` 在转发 DNS 请求时绕过了容器网络命名空间的正常路由规则,导致内部网络上的容器可以意外地将 DNS 请求转发到外部名称服务器。这破坏了内部网络的设计初衷,即限制容器与外部网络的通信。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 是的,该漏洞可能导致容器在运行时影响宿主机或其他容器。攻击者可以通过注册一个受其控制的域名,并利用此漏洞让容器通过 DNS 查询向外发送数据,从而实现数据外泄。虽然这种行为不会直接破坏其他容器或宿主机的安全边界,但它允许容器突破内部网络的隔离限制,间接影响系统的安全性。 ### 结论 条件 1 和 2 均满足,因此返回上述分析结果。 cve: ./data/2024/29xxx/CVE-2024-29964.json Brocade SANnav versions before v2.3.0a do not correctly set permissions on files, including docker files. An unprivileged attacker who gains access to the server can read sensitive information from these files. analysis: 1. 该 CVE 描述中提到权限设置不当的问题,涉及 "docker files"。这表明问题与 Docker 相关文件的权限配置有关,可能间接与容器技术相关,但并未明确提及 namespace、cgroup 或容器隔离机制本身。 2. 由于权限设置不当,可能导致未授权用户访问敏感信息。如果这些敏感信息与 Docker 的配置或运行时数据相关,则可能存在风险,使得攻击者利用此漏洞影响其他容器或宿主机。然而,描述中没有明确说明此问题是否可以直接突破容器隔离或直接影响其他容器及宿主机。 **结论**: 根据上述分析,条件 1 和 2 部分满足,因此返回以下分析结果: 1. 与容器(Docker 文件)相关,但未直接涉及 namespace、cgroup 或隔离机制。 2. 可能通过访问敏感信息间接影响其他容器或宿主机,但具体影响取决于敏感信息的内容和用途。 如果需要更精确的判断,建议进一步了解 "docker files" 的具体内容及其在系统中的作用。 cve: ./data/2024/29xxx/CVE-2024-29967.json In Brocade SANnav before Brocade SANnav v2.31 and v2.3.0a, it was observed that Docker instances inside the appliance have insecure mount points, allowing reading and writing access to sensitive files. The vulnerability could allow a sudo privileged user on the host OS to read and write access to these files. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 该CVE提到Docker实例在设备内部存在不安全的挂载点,允许对敏感文件进行读写访问。这明确涉及容器(Docker)及其挂载点的安全性问题,因此与容器和隔离机制相关。 2. **分析是否会导致容器影响其他容器或宿主机**: 根据描述,漏洞允许具有sudo权限的用户在宿主机操作系统上读取和写入敏感文件。这意味着攻击者可以通过此漏洞突破容器隔离,进而影响宿主机或其他运行在宿主机上的容器。因此,该CVE确实可能导致容器影响宿主机和其他容器。 **结论**:满足条件1和条件2,不需要返回N/A。 cve: ./data/2024/31xxx/CVE-2024-31419.json An information disclosure flaw was found in OpenShift Virtualization. The DownwardMetrics feature was introduced to expose host metrics to virtual machine guests and is enabled by default. This issue could expose limited host metrics of a node to any guest in any namespace without being explicitly enabled by an administrator. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 该CVE描述中提到“DownwardMetrics”功能会暴露宿主机的某些指标给虚拟机guest,且此功能默认启用。虽然主要涉及OpenShift Virtualization,但提到“namespace”,并且与虚拟机guest之间的隔离机制有关,因此可以认为它与namespace和隔离相关。 2. **分析是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 该漏洞导致的是信息泄露问题,而非直接的权限提升或资源访问问题。尽管如此,由于任何guest都可以访问宿主机的部分指标,这可能会间接帮助攻击者了解宿主机的状态或架构,从而为进一步攻击提供线索。不过,这种信息泄露本身不会直接影响其他容器或宿主机的安全性。 3. **结论**: 条件1部分满足(与namespace和隔离相关),条件2不完全满足(不会直接影响其他容器或宿主机)。因此,返回以下分析结果: ``` 1. 与namespace和隔离相关。 2. 不会导致容器直接影响其他容器或宿主机,但可能通过信息泄露间接辅助攻击。 ``` cve: ./data/2024/31xxx/CVE-2024-31989.json Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It has been discovered that an unprivileged pod in a different namespace on the same cluster could connect to the Redis server on port 6379. Despite having installed the latest version of the VPC CNI plugin on the EKS cluster, it requires manual enablement through configuration to enforce network policies. This raises concerns that many clients might unknowingly have open access to their Redis servers. This vulnerability could lead to Privilege Escalation to the level of cluster controller, or to information leakage, affecting anyone who does not have strict access controls on their Redis instance. This issue has been patched in version(s) 2.8.19, 2.9.15 and 2.10.10. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息与namespace和容器隔离相关。问题描述中提到“unprivileged pod in a different namespace”(不同命名空间中的非特权Pod)能够连接到Redis服务器,这表明存在跨命名空间的访问问题。此外,问题涉及Kubernetes集群中的网络策略配置不足,可能导致容器间的隔离性被破坏。 2. **是否会导致容器(如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器影响其他容器或宿主机。由于未正确配置网络策略,非特权Pod可以访问Redis服务器,这可能引发权限提升或信息泄露。攻击者可能利用此漏洞进一步危害同一集群中的其他容器或甚至宿主机,具体取决于Redis服务器上存储的数据和权限。 3. **结论**: 该CVE满足条件1和条件2,因此不会返回“N/A”。 cve: ./data/2024/31xxx/CVE-2024-31994.json Mealie is a self hosted recipe manager and meal planner. Prior to 1.4.0, an attacker can point the image request to an arbitrarily large file. Mealie will attempt to retrieve this file in whole. If it can be retrieved, it may be stored on the file system in whole (leading to possible disk consumption), however the more likely scenario given resource limitations is that the container will OOM during file retrieval if the target file size is greater than the allocated memory of the container. At best this can be used to force the container to infinitely restart due to OOM (if so configured in `docker-compose.yml), or at worst this can be used to force the Mealie container to crash and remain offline. In the event that the file can be retrieved, the lack of rate limiting on this endpoint also permits an attacker to generate ongoing requests to any target of their choice, potentially contributing to an external-facing DoS attack. This vulnerability is fixed in 1.4.0. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息明确提到 Mealie 运行在一个容器中(例如 Docker),并且描述了容器由于内存耗尽(OOM)而崩溃或无限重启的问题。这涉及到容器的资源限制(由 cgroup 管理)以及容器的隔离性。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 该漏洞可能导致 Mealie 容器因 OOM 而崩溃或无限重启,但没有直接证据表明它会影响其他容器或宿主机。然而,如果容器配置了共享资源池(例如未正确设置内存限制),则可能会间接影响其他容器的稳定性。此外,如果攻击者利用此漏洞生成大量外部请求,还可能引发更大范围的 DoS 攻击,从而间接影响宿主机或其他服务。 **结论:** 条件 1 和条件 2 部分满足,因此返回分析结果而非 "N/A"。 cve: ./data/2024/32xxx/CVE-2024-32473.json Moby is an open source container framework that is a key component of Docker Engine, Docker Desktop, and other distributions of container tooling or runtimes. In 26.0.0, IPv6 is not disabled on network interfaces, including those belonging to networks where `--ipv6=false`. An container with an `ipvlan` or `macvlan` interface will normally be configured to share an external network link with the host machine. Because of this direct access, (1) Containers may be able to communicate with other hosts on the local network over link-local IPv6 addresses, (2) if router advertisements are being broadcast over the local network, containers may get SLAAC-assigned addresses, and (3) the interface will be a member of IPv6 multicast groups. This means interfaces in IPv4-only networks present an unexpectedly and unnecessarily increased attack surface. The issue is patched in 26.0.2. To completely disable IPv6 in a container, use `--sysctl=net.ipv6.conf.all.disable_ipv6=1` in the `docker create` or `docker run` command. Or, in the service configuration of a `compose` file. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与容器和隔离相关。它描述了 Moby(Docker 的核心组件)在处理 IPv6 配置时的问题,特别是当 `--ipv6=false` 时,IPv6 并未正确禁用。这直接影响到使用 `ipvlan` 或 `macvlan` 接口的容器,这些接口通常用于共享主机的外部网络链接。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机:** 是的,该漏洞可能导致容器影响其他容器或宿主机。由于 IPv6 未被正确禁用,容器可能会通过链路本地 IPv6 地址与其他主机通信,甚至可能通过 SLAAC 获取分配的地址。此外,容器的网络接口会加入 IPv6 多播组,从而增加攻击面。这种行为可能破坏预期的网络隔离,使容器能够访问不该访问的资源,或者让攻击者利用此漏洞从容器中发起针对宿主机或其他容器的攻击。 3. **结论:** 根据以上分析,条件 1 和条件 2 均满足,因此返回具体分析内容,而不是 "N/A"。 cve: ./data/2024/35xxx/CVE-2024-35139.json IBM Security Access Manager Docker 10.0.0.0 through 10.0.7.1 could allow a local user to obtain sensitive information from the container due to incorrect default permissions. IBM X-Force ID: 292415. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 明确提到 IBM Security Access Manager 的 Docker 容器版本存在默认权限配置错误的问题,这直接影响到容器的安全性以及其隔离机制。因此,它与容器和隔离相关。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 根据描述,由于默认权限配置不正确,本地用户可以利用此漏洞从容器中获取敏感信息。这种权限配置问题可能会破坏容器的隔离性,允许攻击者访问本应被隔离的数据。虽然描述中没有明确提到对其他容器或宿主机的影响,但权限配置错误通常可能进一步被利用来提升权限,从而影响宿主机或其他共享资源的容器。因此,存在一定的风险会影响宿主机或其它容器。 **结论**:满足条件 1 和 2。 cve: ./data/2024/35xxx/CVE-2024-35846.json In the Linux kernel, the following vulnerability has been resolved: mm: zswap: fix shrinker NULL crash with cgroup_disable=memory Christian reports a NULL deref in zswap that he bisected down to the zswap shrinker. The issue also cropped up in the bug trackers of libguestfs [1] and the Red Hat bugzilla [2]. The problem is that when memcg is disabled with the boot time flag, the zswap shrinker might get called with sc->memcg == NULL. This is okay in many places, like the lruvec operations. But it crashes in memcg_page_state() - which is only used due to the non-node accounting of cgroup's the zswap memory to begin with. Nhat spotted that the memcg can be NULL in the memcg-disabled case, and I was then able to reproduce the crash locally as well. [1] https://github.com/libguestfs/libguestfs/issues/139 [2] https://bugzilla.redhat.com/show_bug.cgi?id=2275252 analysis: 1. 该 CVE 信息与 cgroup 相关,因为问题涉及 `cgroup_disable=memory` 引发的内存控制组(memcg)为 NULL 的情况。此外,zswap 和 shrinker 的行为也与 cgroup 的内存管理有关。 2. 尽管该漏洞与 cgroup 相关,但它主要影响内核中 zswap 缩减器的行为,并不会直接影响容器(如 Docker)之间的隔离性或对宿主机的安全性造成威胁。此问题更倾向于在特定配置(如禁用 memcg)下引发崩溃,而不是导致容器逃逸或其他容器受影响的情况。 因此,最终分析结果是: **N/A** cve: ./data/2024/38xxx/CVE-2024-38564.json In the Linux kernel, the following vulnerability has been resolved: bpf: Add BPF_PROG_TYPE_CGROUP_SKB attach type enforcement in BPF_LINK_CREATE bpf_prog_attach uses attach_type_to_prog_type to enforce proper attach type for BPF_PROG_TYPE_CGROUP_SKB. link_create uses bpf_prog_get and relies on bpf_prog_attach_check_attach_type to properly verify prog_type <> attach_type association. Add missing attach_type enforcement for the link_create case. Otherwise, it's currently possible to attach cgroup_skb prog types to other cgroup hooks. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关** 该CVE涉及`BPF_PROG_TYPE_CGROUP_SKB`,这是Linux内核中用于cgroup(控制组)的eBPF程序类型。cgroup是容器技术(如Docker)实现资源限制和隔离的核心机制之一。因此,该漏洞与cgroup直接相关,也间接与容器和隔离机制相关。 2. **分析是否会导致容器在运行时影响其他容器或宿主机** 根据描述,问题在于缺少对`attach_type`的正确验证,可能导致`cgroup_skb`类型的eBPF程序被错误地附加到其他cgroup钩子上。这种错误可能会破坏预期的行为,甚至可能允许攻击者通过精心构造的eBPF程序影响其他cgroup或宿主机的资源管理逻辑。虽然具体影响未明确说明,但理论上这种漏洞可能被利用来绕过容器隔离,进而影响其他容器或宿主机的安全性。 **结论**:满足条件1和条件2,因此返回上述分析内容。 cve: ./data/2024/38xxx/CVE-2024-38663.json In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: fix list corruption from resetting io stat Since commit 3b8cc6298724 ("blk-cgroup: Optimize blkcg_rstat_flush()"), each iostat instance is added to blkcg percpu list, so blkcg_reset_stats() can't reset the stat instance by memset(), otherwise the llist may be corrupted. Fix the issue by only resetting the counter part. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 提到 `blk-cgroup`,这是 Linux 内核中控制块设备 I/O 资源分配和限制的子系统,属于 cgroup(control group)的一部分。因此,该漏洞与 cgroup 相关,而 cgroup 是容器技术(如 Docker)实现资源隔离的重要组成部分。 2. **分析是否会影响其他容器或宿主机**: 该漏洞修复了 `blkcg_reset_stats()` 函数在重置 I/O 统计信息时可能导致链表(llist)损坏的问题。如果链表损坏,可能会导致不可预测的行为,例如内核崩溃或数据不一致。这种问题可能会影响使用相同 cgroup 的其他容器或宿主机的稳定性。因此,此漏洞有可能在特定条件下影响其他容器或宿主机。 **结论**:满足条件 1 和 2,无需返回 "N/A"。 cve: ./data/2024/39xxx/CVE-2024-39503.json In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type Lion Ackermann reported that there is a race condition between namespace cleanup in ipset and the garbage collection of the list:set type. The namespace cleanup can destroy the list:set type of sets while the gc of the set type is waiting to run in rcu cleanup. The latter uses data from the destroyed set which thus leads use after free. The patch contains the following parts: - When destroying all sets, first remove the garbage collectors, then wait if needed and then destroy the sets. - Fix the badly ordered "wait then remove gc" for the destroy a single set case. - Fix the missing rcu locking in the list:set type in the userspace test case. - Use proper RCU list handlings in the list:set type. The patch depends on c1193d9bbbd3 (netfilter: ipset: Add list flush to cancel_gc). analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该漏洞与namespace相关。描述中明确提到“namespace cleanup”和“list:set type”的竞争条件问题,这表明问题发生在网络命名空间(net namespace)的清理过程中。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机** 有可能。由于该漏洞涉及命名空间的竞争条件,并且可能导致“use after free”问题,如果攻击者能够触发这一漏洞,可能会利用它破坏容器之间的隔离性,甚至影响宿主机的稳定性。具体来说,网络命名空间是容器实现网络隔离的重要组成部分,因此该漏洞可能被用来干扰其他容器或宿主机的网络配置。 **结论:满足条件1和条件2,需要进行分析。** cve: ./data/2024/39xxx/CVE-2024-39690.json Capsule is a multi-tenancy and policy-based framework for Kubernetes. In Capsule v0.7.0 and earlier, the tenant-owner can patch any arbitrary namespace that has not been taken over by a tenant (i.e., namespaces without the ownerReference field), thereby gaining control of that namespace. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与 namespace 相关。Capsule 是一个基于 Kubernetes 的多租户框架,而问题的核心在于 tenant-owner 可以 patch 未被租户接管的任意 namespace(即没有 `ownerReference` 字段的 namespace)。这直接影响了 Kubernetes 中 namespace 的管理和控制。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 不会直接导致容器运行时影响其他容器或宿主机。此漏洞主要涉及 namespace 的管理权限问题,而不是容器运行时的隔离性或 cgroup 配置问题。虽然 namespace 是容器隔离的一部分,但这里的漏洞并不直接影响容器的运行时行为或宿主机的安全性。 3. **结论**: 由于条件 1 满足,条件 2 不满足,因此返回分析结果而非 "N/A"。 cve: ./data/2024/3xxx/CVE-2024-3033.json An improper authorization vulnerability exists in the mintplex-labs/anything-llm application, specifically within the '/api/v/' endpoint and its sub-routes. This flaw allows unauthenticated users to perform destructive actions on the VectorDB, including resetting the database and deleting specific namespaces, without requiring any authorization or permissions. The issue affects all versions up to and including the latest version, with a fix introduced in version 1.0.0. Exploitation of this vulnerability can lead to complete data loss of document embeddings across all workspaces, rendering workspace chats and embeddable chat widgets non-functional. Additionally, attackers can list all namespaces, potentially exposing private workspace names. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该漏洞涉及 "namespace"。描述中提到攻击者可以删除特定的 namespaces,并列出所有 namespaces,这表明问题与 namespaces 的管理和操作有关。然而,这里的 namespace 特指 VectorDB 中的数据组织单元,而非 Linux 命名空间(如用于容器隔离的 namespace)。因此,它与容器或隔离机制没有直接关联。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 不会。此漏洞仅影响 mintplex-labs/anything-llm 应用程序中的 VectorDB 数据管理功能,导致数据丢失或暴露。它并不涉及容器的底层技术(如 cgroup 或 namespace),也不会突破容器的隔离机制去影响其他容器或宿主机。 --- 综上所述,虽然 CVE 提到 "namespace",但它是数据库上下文中的概念,而不是容器隔离相关的 Linux 命名空间。同时,该漏洞不会对容器运行时或其他容器及宿主机产生影响。 **结论:N/A** cve: ./data/2024/3xxx/CVE-2024-3056.json A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that, when configured to share the same IPC with at least one other container, can create a large number of IPC resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created are not. Those resources are tied to the IPC namespace that will not be removed until all containers using it are stopped, and one non-malicious container is holding the namespace open. The malicious container is restarted, either automatically or by attacker control, repeating the process and increasing the amount of memory consumed. With a container configured to restart always, such as `podman run --restart=always`, this can result in a memory-based denial of service of the system. analysis: 1. **是否与 namespace、cgroup、container 或容器隔离相关**: 是的,该 CVE 信息与 namespace 和 cgroup 直接相关。问题描述中提到 IPC(进程间通信)共享和 IPC 命名空间的概念,并且涉及 cgroup 的资源管理机制。攻击者通过创建恶意容器,在共享的 IPC 命名空间中生成大量 IPC 资源(如 `/dev/shm` 中的对象),导致资源耗尽。 2. **是否会导致容器在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器运行时影响其他容器或宿主机。具体来说,恶意容器可以消耗大量的内存资源(通过 `/dev/shm`),即使该容器被 OOM 杀死,其创建的 IPC 资源仍然存在,因为这些资源绑定到 IPC 命名空间,而 IPC 命名空间只有在所有使用它的容器停止后才会释放。如果有一个非恶意容器保持 IPC 命名空间打开,恶意容器可以反复重启并继续消耗更多内存,最终可能导致宿主机上的内存耗尽,引发系统级的拒绝服务(DoS)。 **结论**:满足条件 1 和 2。 cve: ./data/2024/40xxx/CVE-2024-40949.json In the Linux kernel, the following vulnerability has been resolved: mm: shmem: fix getting incorrect lruvec when replacing a shmem folio When testing shmem swapin, I encountered the warning below on my machine. The reason is that replacing an old shmem folio with a new one causes mem_cgroup_migrate() to clear the old folio's memcg data. As a result, the old folio cannot get the correct memcg's lruvec needed to remove itself from the LRU list when it is being freed. This could lead to possible serious problems, such as LRU list crashes due to holding the wrong LRU lock, and incorrect LRU statistics. To fix this issue, we can fallback to use the mem_cgroup_replace_folio() to replace the old shmem folio.

Let's rework this overflow checking logic to not actually perform an overflow during the check itself, thus avoiding the UBSAN splat. [1]: https://github.com/llvm/llvm-project/pull/82432 analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 从描述中可以看到,这个漏洞涉及 `cgroup: Invalid name` 的信息,表明它与 cgroup(控制组)相关。cgroup 是 Linux 内核中的一个功能模块,用于限制、记录和隔离进程组的资源(如 CPU、内存、磁盘 I/O 等)。因此,这个 CVE 与 cgroup 直接相关,而 cgroup 是容器技术(如 Docker)实现资源隔离的重要组成部分。 2. **是否会导致容器在运行时影响其他容器或宿主机** 虽然这个漏洞涉及到 cgroup,但从描述来看,主要问题是一个整数溢出检查逻辑的问题,导致 UBSAN(Undefined Behavior Sanitizer)触发了一个警告(splat)。这种问题通常不会直接导致容器突破隔离,也不会直接影响其他容器或宿主机的安全性。然而,如果攻击者能够利用这个整数溢出问题触发更严重的后果(如内存损坏或内核崩溃),则可能间接影响容器的稳定性或宿主机的安全性。但根据目前提供的信息,没有明确证据表明该漏洞可以直接被利用来突破容器隔离。 3. **结论** 根据上述分析,这个 CVE 与 cgroup 相关,但没有明确证据表明它会导致容器突破隔离或影响其他容器及宿主机。因此,最终结论为: **N/A** cve: ./data/2024/41xxx/CVE-2024-41010.json In the Linux kernel, the following vulnerability has been resolved: bpf: Fix too early release of tcx_entry Pedro Pinto and later independently also Hyunwoo Kim and Wongi Lee reported an issue that the tcx_entry can be released too early leading to a use after free (UAF) when an active old-style ingress or clsact qdisc with a shared tc block is later replaced by another ingress or clsact instance. Essentially, the sequence to trigger the UAF (one example) can be as follows: 1. A network namespace is created 2. An ingress qdisc is created. This allocates a tcx_entry, and &tcx_entry->miniq is stored in the qdisc's miniqp->p_miniq. At the same time, a tcf block with index 1 is created. 3. chain0 is attached to the tcf block. chain0 must be connected to the block linked to the ingress qdisc to later reach the function tcf_chain0_head_change_cb_del() which triggers the UAF. 4. Create and graft a clsact qdisc. This causes the ingress qdisc created in step 1 to be removed, thus freeing the previously linked tcx_entry: rtnetlink_rcv_msg() => tc_modify_qdisc() => qdisc_create() => clsact_init() [a] => qdisc_graft() => qdisc_destroy() => __qdisc_destroy() => ingress_destroy() [b] => tcx_entry_free() => kfree_rcu() // tcx_entry freed 5. Finally, the network namespace is closed. This registers the cleanup_net worker, and during the process of releasing the remaining clsact qdisc, it accesses the tcx_entry that was already freed in step 4, causing the UAF to occur: cleanup_net() => ops_exit_list() => default_device_exit_batch() => unregister_netdevice_many() => unregister_netdevice_many_notify() => dev_shutdown() => qdisc_put() => clsact_destroy() [c] => tcf_block_put_ext() => tcf_chain0_head_change_cb_del() => tcf_chain_head_change_item() => clsact_chain_head_change() => mini_qdisc_pair_swap() // UAF There are also other variants, the gist is to add an ingress (or clsact) qdisc with a specific shared block, then to replace that qdisc, waiting for the tcx_entry kfree_rcu() to be executed and subsequently accessing the current active qdisc's miniq one way or another. The correct fix is to turn the miniq_active boolean into a counter. What can be observed, at step 2 above, the counter transitions from 0->1, at step [a] from 1->2 (in order for the miniq object to remain active during the replacement), then in [b] from 2->1 and finally [c] 1->0 with the eventual release. The reference counter in general ranges from [0,2] and it does not need to be atomic since all access to the counter is protected by the rtnl mutex. With this in place, there is no longer a UAF happening and the tcx_entry is freed at the correct time. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关** 是的,这个 CVE 信息与 namespace 相关。具体来说,问题涉及到网络命名空间 (network namespace) 的使用。在步骤 1 中明确提到创建了一个网络命名空间,并且后续的操作(如 qdisc 的创建和销毁)都在该命名空间中进行。网络命名空间是 Linux 容器(如 Docker)实现网络隔离的重要组成部分。 2. **分析是否会导致容器在运行时影响其他容器或宿主机** 这个漏洞可能导致 Use-After-Free (UAF) 问题,从而可能被利用来破坏容器的隔离性。具体来说,如果攻击者能够在容器内触发此漏洞,则可能通过 UAF 访问或操控已经释放的内存,进而影响宿主机或其他容器的稳定性甚至安全性。虽然该漏洞本身并不直接针对容器技术,但由于它涉及网络命名空间,而网络命名空间是容器网络隔离的核心机制之一,因此该漏洞可能会间接影响容器的隔离性。 3. **结论** 条件 1 和条件 2 均满足,因此需要返回上述分析内容,而不是 "N/A"。 cve: ./data/2024/41xxx/CVE-2024-41110.json Moby is an open-source project created by Docker for software containerization. A security vulnerability has been detected in certain versions of Docker Engine, which could allow an attacker to bypass authorization plugins (AuthZ) under specific circumstances. The base likelihood of this being exploited is low. Using a specially-crafted API request, an Engine API client could make the daemon forward the request or response to an authorization plugin without the body. In certain circumstances, the authorization plugin may allow a request which it would have otherwise denied if the body had been forwarded to it. A security issue was discovered In 2018, where an attacker could bypass AuthZ plugins using a specially crafted API request. This could lead to unauthorized actions, including privilege escalation. Although this issue was fixed in Docker Engine v18.09.1 in January 2019, the fix was not carried forward to later major versions, resulting in a regression. Anyone who depends on authorization plugins that introspect the request and/or response body to make access control decisions is potentially impacted. Docker EE v19.03.x and all versions of Mirantis Container Runtime are not vulnerable. docker-ce v27.1.1 containes patches to fix the vulnerability. Patches have also been merged into the master, 19.03, 20.0, 23.0, 24.0, 25.0, 26.0, and 26.1 release branches. If one is unable to upgrade immediately, avoid using AuthZ plugins and/or restrict access to the Docker API to trusted parties, following the principle of least privilege. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 描述的是 Docker Engine 中的一个授权插件 (AuthZ) 绕过漏洞,涉及 API 请求的处理。虽然它与容器技术(Docker)相关,但并未直接提到或涉及 namespace、cgroup 或容器隔离机制。 2. **分析是否会导致容器在运行时影响其他容器或宿主机**: 此漏洞允许通过精心构造的 API 请求绕过授权检查,从而可能导致未经授权的操作,包括潜在的权限提升。如果攻击者利用此漏洞成功绕过授权插件,他们可能执行未被允许的操作,例如访问或修改其他容器资源,甚至可能影响宿主机的安全性。因此,该漏洞有可能导致容器运行时影响其他容器或宿主机。 3. **结论**: 条件 1 和条件 2 至少有一个满足,因此返回分析结果而非 "N/A"。 cve: ./data/2024/41xxx/CVE-2024-41932.json In the Linux kernel, the following vulnerability has been resolved: sched: fix warning in sched_setaffinity Commit 8f9ea86fdf99b added some logic to sched_setaffinity that included a WARN when a per-task affinity assignment races with a cpuset update. Specifically, we can have a race where a cpuset update results in the task affinity no longer being a subset of the cpuset. That's fine; we have a fallback to instead use the cpuset mask. However, we have a WARN set up that will trigger if the cpuset mask has no overlap at all with the requested task affinity. This shouldn't be a warning condition; its trivial to create this condition. Reproduced the warning by the following setup: - $PID inside a cpuset cgroup - another thread repeatedly switching the cpuset cpus from 1-2 to just 1 - another thread repeatedly setting the $PID affinity (via taskset) to 2 analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关** 是的,这个 CVE 信息与 cgroup 和隔离相关。问题涉及到 `sched_setaffinity` 函数中任务亲和性(task affinity)与 cpuset 更新之间的竞争条件。`cpuset` 是 Linux 控制组(cgroup)子系统的一部分,用于限制进程可以在哪些 CPU 上运行以及可以访问哪些内存节点。因此,这个问题直接涉及 cgroup 的功能。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机** 可能会。由于问题涉及到 `cpuset` 和任务亲和性的竞争条件,如果一个容器的任务亲和性设置与宿主机的 cpuset 配置发生冲突,可能会触发警告(WARN)。虽然当前的修复只是去掉了不必要的警告,但如果类似的竞争条件未被妥善处理,可能会导致更严重的问题,例如任务调度异常或性能下降。这种异常可能会影响同一宿主机上的其他容器或宿主机本身。 ### 结论: - 该 CVE 与 cgroup 和容器隔离相关。 - 存在潜在风险,可能影响同一宿主机上的其他容器或宿主机。 cve: ./data/2024/41xxx/CVE-2024-41968.json A low privileged remote attacker may modify the docker settings setup of the device, leading to a limited DoS. analysis: 1. 该 CVE 描述中提到 "docker settings",因此与容器(Docker)相关。 2. 攻击者可以修改 Docker 的设置,导致有限的拒绝服务(DoS)。这可能会影响其他容器或宿主机的正常运行,因为 Docker 设置的更改可能会波及到整个 Docker 环境及其上的所有容器。 结论:满足条件 1 和条件 2。 cve: ./data/2024/41xxx/CVE-2024-41997.json An issue was discovered in version of Warp Terminal prior to 2024.07.18 (v0.2024.07.16.08.02). A command injection vulnerability exists in the Docker integration functionality. An attacker can create a specially crafted hyperlink using the `warp://action/docker/open_subshell` intent that when clicked by the victim results in command execution on the victim's machine. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与容器相关。问题出现在 Warp Terminal 的 Docker 集成功能中,涉及通过 `warp://action/docker/open_subshell` 意图触发的操作,这表明它与 Docker 容器的交互有关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 这个漏洞可能导致命令注入,从而使攻击者能够在受害者的机器上执行命令。由于命令执行发生在受害者机器上,而该功能与 Docker 集成相关,因此有可能利用此漏洞影响宿主机或宿主机上的其他容器,具体取决于攻击者注入的命令以及 Docker 环境的配置。 **结论:** - 该漏洞与容器和隔离机制相关。 - 可能会影响宿主机或其他容器,具体取决于攻击场景和环境配置。 cve: ./data/2024/42xxx/CVE-2024-42486.json Cilium is a networking, observability, and security solution with an eBPF-based dataplane. In versions on the 1.15.x branch prior to 1.15.8 and the 1.16.x branch prior to 1.16.1, ReferenceGrant changes are not correctly propagated in Cilium's GatewayAPI controller, which could lead to Gateway resources being able to access secrets for longer than intended, or to Routes having the ability to forward traffic to backends in other namespaces for longer than intended. This issue has been patched in Cilium v1.15.8 and v1.16.1. As a workaround, any modification of a related Gateway/HTTPRoute/GRPCRoute/TCPRoute CRD (for example, adding any label to any of these resources) will trigger a reconciliation of ReferenceGrants on an affected cluster. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与 namespace 相关。问题描述中提到 "Routes having the ability to forward traffic to backends in other namespaces for longer than intended",这表明由于 ReferenceGrant 的传播错误,可能导致某些资源(如 Gateway 或 Route)访问其他命名空间中的后端服务或敏感数据。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 虽然该问题涉及跨命名空间的流量转发,但它主要影响 Cilium 的网络控制平面和 GatewayAPI 的行为,而不是直接破坏容器的隔离性或影响宿主机的安全性。因此,虽然它可能间接影响容器间的通信(例如,允许不适当的跨命名空间访问),但不会直接导致容器逃逸或直接影响宿主机。 **结论:** 该 CVE 与 namespace 和容器网络相关,可能间接影响容器间的隔离性,但不会直接影响宿主机或其他容器的安全性。 cve: ./data/2024/43xxx/CVE-2024-43397.json Apollo is a configuration management system. A vulnerability exists in the synchronization configuration feature that allows users to craft specific requests to bypass permission checks. This exploit enables them to modify a namespace without the necessary permissions. The issue was addressed with an input parameter check which was released in version 2.3.0. analysis: 1. 该 CVE 信息与 namespace 相关,因为它提到了用户可以通过构造特定请求绕过权限检查来修改 namespace。然而,这里的 namespace 是指 Apollo 配置管理系统中的配置命名空间,而不是操作系统或容器相关的 namespace。 2. 该 CVE 不涉及容器(如 Docker)的运行时行为,也不会影响其他容器或宿主机。它仅影响 Apollo 配置管理系统的权限控制机制。 3. 由于条件 1 和 2 中的部分内容不完全满足(仅与 Apollo 系统中的 namespace 相关,但不涉及容器或隔离技术),因此不符合完全不满足的 N/A 条件。 **结论:N/A** cve: ./data/2024/43xxx/CVE-2024-43803.json The Bare Metal Operator (BMO) implements a Kubernetes API for managing bare metal hosts in Metal3. The `BareMetalHost` (BMH) CRD allows the `userData`, `metaData`, and `networkData` for the provisioned host to be specified as links to Kubernetes Secrets. There are fields for both the `Name` and `Namespace` of the Secret, meaning that versions of the baremetal-operator prior to 0.8.0, 0.6.2, and 0.5.2 will read a `Secret` from any namespace. A user with access to create or edit a `BareMetalHost` can thus exfiltrate a `Secret` from another namespace by using it as e.g. the `userData` for provisioning some host (note that this need not be a real host, it could be a VM somewhere). BMO will only read a key with the name `value` (or `userData`, `metaData`, or `networkData`), so that limits the exposure somewhat. `value` is probably a pretty common key though. Secrets used by _other_ `BareMetalHost`s in different namespaces are always vulnerable. It is probably relatively unusual for anyone other than cluster administrators to have RBAC access to create/edit a `BareMetalHost`. This vulnerability is only meaningful, if the cluster has users other than administrators and users' privileges are limited to their respective namespaces. The patch prevents BMO from accepting links to Secrets from other namespaces as BMH input. Any BMH configuration is only read from the same namespace only. The problem is patched in BMO releases v0.7.0, v0.6.2 and v0.5.2 and users should upgrade to those versions. Prior upgrading, duplicate the BMC Secrets to the namespace where the corresponding BMH is. After upgrade, remove the old Secrets. As a workaround, an operator can configure BMO RBAC to be namespace scoped for Secrets, instead of cluster scoped, to prevent BMO from accessing Secrets from other namespaces. analysis: 1. **分析这个CVE信息是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该CVE与namespace相关。问题的核心在于Bare Metal Operator (BMO) 在处理 `Secret` 时,允许从任意namespace读取数据,而不是限制在当前namespace内。这破坏了Kubernetes中namespace之间的隔离性。 2. **分析这个CVE是否会导致容器(例如Docker等)在运行时会影响其他容器或宿主机:** 不会直接影响容器或宿主机。此漏洞主要影响的是Kubernetes中的namespace隔离机制,使得具有特定权限的用户可以跨namespace访问敏感数据(如Secret)。虽然它不直接涉及容器运行时的行为,但间接可能导致敏感信息泄露,从而对整个集群的安全性造成威胁。 3. **结论:** 由于条件1满足,条件2不满足,因此返回以下分析结果: - 与namespace隔离相关,可能导致跨namespace的数据泄露。 - 不直接影响容器运行时或其他容器/宿主机的安全性。 cve: ./data/2024/43xxx/CVE-2024-43853.json In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: Prevent UAF in proc_cpuset_show() An UAF can happen when /proc/cpuset is read as reported in [1].

In cgroup v1, the mount operation will allocate cgroup_root, and top_cpuset.css.cgrp will point to the allocated &cgroup_root.cgrp. When the umount operation is executed, top_cpuset.css.cgrp will be rebound to &cgrp_dfl_root.cgrp. The problem is that when rebinding to cgrp_dfl_root, there are cases where the cgroup_root allocated by setting up the root for cgroup v1 is cached. This could lead to a Use-After-Free (UAF) if it is subsequently freed. The descendant cgroups of cgroup v1 can only be freed after the css is released. However, the css of the root will never be released, yet the cgroup_root should be freed when it is unmounted. This means that obtaining a reference to the css of the root does not guarantee that css.cgrp->root will not be freed. Fix this problem by using rcu_read_lock in proc_cpuset_show(). As cgroup_root is kfree_rcu after commit d23b5c577715 ("cgroup: Make operations on the cgroup root_list RCU safe"), css->cgroup won't be freed during the critical section. To call cgroup_path_ns_locked, css_set_lock is needed, so it is safe to replace task_get_css with task_css.

Fix it by adding missing rcu read lock. Found by code inspection. [songmuchun@bytedance.com: only grab rcu lock when necessary, per Vlastimil] analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与 cgroup 相关。具体来说,问题出现在 `mem_cgroup_from_slab_obj()` 函数中,该函数用于从 slab 对象中获取内存控制组(memory cgroup)。cgroup 是 Linux 内核中用于限制和隔离资源使用的重要机制,广泛应用于容器技术(如 Docker)中以实现资源隔离。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 可能会。由于该漏洞涉及内存 cgroup 的使用,如果未正确处理 RCU 锁,可能会导致 Use-After-Free (UAF) 问题。这种问题可能被恶意利用,从而破坏内存隔离性。在容器环境中,这可能导致一个容器访问或影响其他容器或宿主机的内存资源,进而引发安全风险。 **结论**:满足条件 1 和 2,因此需要进行上述分析。 cve: ./data/2024/43xxx/CVE-2024-43892.json In the Linux kernel, the following vulnerability has been resolved: memcg: protect concurrent access to mem_cgroup_idr Commit 73f576c04b94 ("mm: memcontrol: fix cgroup creation failure after many small jobs") decoupled the memcg IDs from the CSS ID space to fix the cgroup creation failures. It introduced IDR to maintain the memcg ID space. The IDR depends on external synchronization mechanisms for modifications. For the mem_cgroup_idr, the idr_alloc() and idr_replace() happen within css callback and thus are protected through cgroup_mutex from concurrent modifications. However idr_remove() for mem_cgroup_idr was not protected against concurrency and can be run concurrently for different memcgs when they hit their refcnt to zero. Fix that. We have been seeing list_lru based kernel crashes at a low frequency in our fleet for a long time. These crashes were in different part of list_lru code including list_lru_add(), list_lru_del() and reparenting code. Upon further inspection, it looked like for a given object (dentry and inode), the super_block's list_lru didn't have list_lru_one for the memcg of that object. The initial suspicions were either the object is not allocated through kmem_cache_alloc_lru() or somehow memcg_list_lru_alloc() failed to allocate list_lru_one() for a memcg but returned success. No evidence were found for these cases. Looking more deeply, we started seeing situations where valid memcg's id is not present in mem_cgroup_idr and in some cases multiple valid memcgs have same id and mem_cgroup_idr is pointing to one of them. So, the most reasonable explanation is that these situations can happen due to race between multiple idr_remove() calls or race between idr_alloc()/idr_replace() and idr_remove(). These races are causing multiple memcgs to acquire the same ID and then offlining of one of them would cleanup list_lrus on the system for all of them. Later access from other memcgs to the list_lru cause crashes due to missing list_lru_one. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,这个 CVE 信息与 cgroup(控制组)直接相关。具体来说,问题出在 `memcg`(内存控制组)中对 `mem_cgroup_idr` 的并发访问保护不足。`memcg` 是 Linux 内核中用于管理内存资源分配和限制的重要机制,广泛应用于容器技术(如 Docker)中的资源隔离。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 是的,这个问题可能会导致容器运行时影响其他容器或宿主机。由于 `memcg` 是容器资源隔离的核心组件之一,如果 `mem_cgroup_idr` 的并发访问未被正确保护,可能导致以下后果: - 不同容器之间的内存资源分配出现竞争或冲突。 - 宿主机上的全局内存管理结构(如 `list_lru`)可能因错误的清理操作而崩溃,进而影响整个系统的稳定性。 - 某个容器的资源释放操作可能误删其他容器或宿主机的内存管理数据结构,导致系统不稳定或崩溃。 因此,该漏洞确实可能破坏容器之间的隔离性,并对宿主机造成潜在威胁。 **结论:满足条件 1 和 2。** cve: ./data/2024/44xxx/CVE-2024-44975.json In the Linux kernel, the following vulnerability has been resolved: cgroup/cpuset: fix panic caused by partcmd_update We find a bug as below: BUG: unable to handle page fault for address: 00000003 PGD 0 P4D 0 Oops: 0000 [#1] PREEMPT SMP NOPTI CPU: 3 PID: 358 Comm: bash Tainted: G W I 6.6.0-10893-g60d6 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/4 RIP: 0010:partition_sched_domains_locked+0x483/0x600 Code: 01 48 85 d2 74 0d 48 83 05 29 3f f8 03 01 f3 48 0f bc c2 89 c0 48 9 RSP: 0018:ffffc90000fdbc58 EFLAGS: 00000202 RAX: 0000000100000003 RBX: ffff888100b3dfa0 RCX: 0000000000000000 RDX: 0000000000000000 RSI: 0000000000000000 RDI: 000000000002fe80 RBP: ffff888100b3dfb0 R08: 0000000000000001 R09: 0000000000000000 R10: ffffc90000fdbcb0 R11: 0000000000000004 R12: 0000000000000002 R13: ffff888100a92b48 R14: 0000000000000000 R15: 0000000000000000 FS: 00007f44a5425740(0000) GS:ffff888237d80000(0000) knlGS:0000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000100030973 CR3: 000000010722c000 CR4: 00000000000006e0 Call Trace: ? show_regs+0x8c/0xa0 ? __die_body+0x23/0xa0 ? __die+0x3a/0x50 ? page_fault_oops+0x1d2/0x5c0 ? partition_sched_domains_locked+0x483/0x600 ? search_module_extables+0x2a/0xb0 ? search_exception_tables+0x67/0x90 ? kernelmode_fixup_or_oops+0x144/0x1b0 ? __bad_area_nosemaphore+0x211/0x360 ? up_read+0x3b/0x50 ? bad_area_nosemaphore+0x1a/0x30 ? exc_page_fault+0x890/0xd90 ? __lock_acquire.constprop.0+0x24f/0x8d0 ? __lock_acquire.constprop.0+0x24f/0x8d0 ? asm_exc_page_fault+0x26/0x30 ? partition_sched_domains_locked+0x483/0x600 ? partition_sched_domains_locked+0xf0/0x600 rebuild_sched_domains_locked+0x806/0xdc0 update_partition_sd_lb+0x118/0x130 cpuset_write_resmask+0xffc/0x1420 cgroup_file_write+0xb2/0x290 kernfs_fop_write_iter+0x194/0x290 new_sync_write+0xeb/0x160 vfs_write+0x16f/0x1d0 ksys_write+0x81/0x180 __x64_sys_write+0x21/0x30 x64_sys_call+0x2f25/0x4630 do_syscall_64+0x44/0xb0 entry_SYSCALL_64_after_hwframe+0x78/0xe2 RIP: 0033:0x7f44a553c887 It can be reproduced with cammands: cd /sys/fs/cgroup/ mkdir test cd test/ echo +cpuset > ../cgroup.subtree_control echo root > cpuset.cpus.partition cat /sys/fs/cgroup/cpuset.cpus.effective 0-3 echo 0-3 > cpuset.cpus // taking away all cpus from root This issue is caused by the incorrect rebuilding of scheduling domains.

While this could be used to create empty files, existing files would not be truncated. An attacker must have the ability to start containers using some kind of custom volume configuration. Containers using user namespaces are still affected, but the scope of places an attacker can create inodes can be significantly reduced. Sufficiently strict LSM policies (SELinux/Apparmor) can also in principle block this attack -- we suspect the industry standard SELinux policy may restrict this attack's scope but the exact scope of protection hasn't been analysed. This is exploitable using runc directly as well as through Docker and Kubernetes. The issue is fixed in runc v1.1.14 and v1.2.0-rc3. Some workarounds are available. Using user namespaces restricts this attack fairly significantly such that the attacker can only create inodes in directories that the remapped root user/group has write access to. Unless the root user is remapped to an actual user on the host (such as with rootless containers that don't use `/etc/sub[ug]id`), this in practice means that an attacker would only be able to create inodes in world-writable directories. A strict enough SELinux or AppArmor policy could in principle also restrict the scope if a specific label is applied to the runc runtime, though neither the extent to which the standard existing policies block this attack nor what exact policies are needed to sufficiently restrict this attack have been thoroughly tested. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该 CVE 与容器和隔离相关。具体来说,它涉及 `runc` 工具(用于根据 OCI 规范运行容器)以及容器之间的共享卷配置。问题的核心是一个竞争条件漏洞,攻击者可以通过共享卷在宿主机文件系统中创建空文件或目录。 2. **分析是否会导致容器在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器影响宿主机或其他容器。攻击者可以利用此漏洞通过共享卷在宿主机文件系统的任意位置创建空文件或目录。虽然现有文件不会被截断,但这种行为可能破坏宿主机的文件系统完整性,从而间接影响其他容器的正常运行。 3. **结论**: 条件 1 和条件 2 均满足,因此返回上述分析结果。 cve: ./data/2024/45xxx/CVE-2024-45313.json Overleaf is a web-based collaborative LaTeX editor. When installing Server Pro using the Overleaf Toolkit from before 2024-07-17 or legacy docker-compose.yml from before 2024-08-28, the configuration for LaTeX compiles was insecure by default, requiring the administrator to enable the security features via a configuration setting (`SIBLING_CONTAINERS_ENABLED` in Toolkit, `SANDBOXED_COMPILES` in legacy docker-compose/custom deployments). If these security features are not enabled then users have access to the `sharelatex` container resources (filesystem, network, environment variables) when running compiles, leading to multiple file access vulnerabilities, either directly or via symlinks created during compiles. The setting has now been changed to be secure by default for new installs in the Toolkit and legacy docker-compose deployment. The Overleaf Toolkit has been updated to set `SIBLING_CONTAINERS_ENABLED=true` by default for new installs. It is recommended that any existing installations using the previous default setting migrate to using sibling containers. Existing installations can set `SIBLING_CONTAINERS_ENABLED=true` in `config/overleaf.rc` as a mitigation. In legacy docker-compose/custom deployments `SANDBOXED_COMPILES=true` should be used. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该CVE信息明确提到与容器(`sharelatex` 容器)及其资源访问相关。具体来说,如果未启用安全特性(如 `SIBLING_CONTAINERS_ENABLED` 或 `SANDBOXED_COMPILES`),用户可以在运行 LaTeX 编译时访问容器的文件系统、网络和环境变量,这涉及容器的隔离问题。 2. **是否会导致容器在运行时影响其他容器或宿主机:** 是的,由于默认配置不安全,用户可以访问 `sharelatex` 容器的资源(包括文件系统、网络等)。这种访问权限可能会被滥用,从而影响其他容器或宿主机的安全性。例如,通过文件系统访问或网络操作,攻击者可能进一步突破隔离边界,危害整个容器环境或宿主机。 **结论:满足条件1和条件2。** cve: ./data/2024/45xxx/CVE-2024-45497.json A flaw was found in the OpenShift build process, where the docker-build container is configured with a hostPath volume mount that maps the node's /var/lib/kubelet/config.json file into the build pod. This file contains sensitive credentials necessary for pulling images from private repositories. The mount is not read-only, which allows the attacker to overwrite it. By modifying the config.json file, the attacker can cause a denial of service by preventing the node from pulling new images and potentially exfiltrating sensitive secrets. This flaw impacts the availability of services dependent on image pulls and exposes sensitive information to unauthorized parties. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器和隔离相关。问题出现在 OpenShift 的构建过程中,涉及 `docker-build` 容器配置了一个 `hostPath` 卷挂载,将宿主机的 `/var/lib/kubelet/config.json` 文件映射到构建 Pod 中。由于挂载不是只读的,攻击者可以修改该文件,从而破坏节点的正常功能并泄露敏感信息。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 是的,此漏洞会影响宿主机和其他容器。通过修改 `/var/lib/kubelet/config.json` 文件,攻击者可以阻止节点拉取新镜像,导致依赖这些镜像的服务不可用(DoS)。此外,攻击者还可以窃取文件中的敏感凭据,进一步威胁宿主机的安全性,并可能利用这些凭据访问私有镜像仓库或其他资源。 **结论**:满足条件 1 和 2。 cve: ./data/2024/49xxx/CVE-2024-49974.json In the Linux kernel, the following vulnerability has been resolved: NFSD: Limit the number of concurrent async COPY operations Nothing appears to limit the number of concurrent async COPY operations that clients can start. In addition, AFAICT each async COPY can copy an unlimited number of 4MB chunks, so can run for a long time. Thus IMO async COPY can become a DoS vector. Add a restriction mechanism that bounds the number of concurrent background COPY operations. Start simple and try to be fair -- this patch implements a per-namespace limit. An async COPY request that occurs while this limit is exceeded gets NFS4ERR_DELAY. The requesting client can choose to send the request again after a delay or fall back to a traditional read/write style copy. If there is need to make the mechanism more sophisticated, we can visit that in future patches. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,此 CVE 与 namespace 相关。漏洞描述中提到实现了一个“per-namespace limit”机制,用于限制每个命名空间中并发的异步 COPY 操作数量。这表明该漏洞涉及 Linux 命名空间的使用。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 可能会。由于该漏洞涉及到 NFS 异步 COPY 操作的限制机制,并且是基于命名空间的限制,如果一个容器(或客户端)滥用异步 COPY 操作(例如发起大量请求),可能会导致资源耗尽,从而影响同一宿主机上的其他容器或宿主机本身。这种行为可能成为一种 DoS(拒绝服务)攻击向量。 因此,该 CVE 满足条件 1 和条件 2。 cve: ./data/2024/4xxx/CVE-2024-4369.json An information disclosure flaw was found in OpenShift's internal image registry operator. The AZURE_CLIENT_SECRET can be exposed through an environment variable defined in the pod definition, but is limited to Azure environments. An attacker controlling an account that has high enough permissions to obtain pod information from the openshift-image-registry namespace could use this obtained client secret to perform actions as the registry operator's Azure service account. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,这个 CVE 信息与 namespace 和容器相关。问题出现在 OpenShift 的内部镜像 registry operator 中,涉及 `openshift-image-registry` 命名空间中的 Pod 定义。Pod 是 Kubernetes/容器编排系统中的基本单元,因此该问题直接与容器环境相关。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 这个漏洞本身不会直接影响其他容器或宿主机的安全性。它主要是一个信息泄露问题,泄露的是 Azure 环境下的 `AZURE_CLIENT_SECRET`。然而,如果攻击者获取了该密钥,他们可以利用该密钥以 registry operator 的 Azure 服务账户身份执行操作,这可能会间接影响整个 Azure 环境中的资源,包括可能影响其他容器或宿主机。因此,虽然漏洞本身不直接导致容器逃逸或宿主机受攻击,但其后果可能被扩展到更广泛的范围。 **结论:** - 满足条件 1 和 2 的部分分析要求。 - 不属于完全无关的情况,因此不返回 "N/A"。 cve: ./data/2024/50xxx/CVE-2024-50130.json In the Linux kernel, the following vulnerability has been resolved: netfilter: bpf: must hold reference on net namespace BUG: KASAN: slab-use-after-free in __nf_unregister_net_hook+0x640/0x6b0 Read of size 8 at addr ffff8880106fe400 by task repro/72= bpf_nf_link_release+0xda/0x1e0 bpf_link_free+0x139/0x2d0 bpf_link_release+0x68/0x80 __fput+0x414/0xb60 Eric says: It seems that bpf was able to defer the __nf_unregister_net_hook() after exit()/close() time.

This affects versions of the argo-workflows Chart that use appVersion: 3.4 and above, which no longer need these permissions for the only available Executor, Emissary. It could also affect users below 3.4 depending on their choice of Executor in those versions. This only affects the Helm Chart and not the upstream manifests. This vulnerability is fixed in 0.44.0. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息与 namespace 和容器相关。问题的核心在于 Argo Workflows 的 Helm Chart 中的 `workflow-role` 权限过高,允许恶意模板执行任意代码,并通过 `kubectl exec` 进入同一 namespace 下的任何 Pod。这直接影响了 Kubernetes 集群中的 namespace 隔离性。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机:** 是的,此漏洞可能导致容器间的隔离被破坏。攻击者可以通过恶意模板利用 excessive privileges 创建新的 Pods 或对现有 Pods 执行命令,从而影响同一 namespace 下的其他容器。虽然直接影响宿主机的可能性较低(除非进一步利用其他漏洞),但 namespace 内的资源完全暴露于风险中。 **结论:满足条件 1 和 2。** cve: ./data/2024/53xxx/CVE-2024-53095.json In the Linux kernel, the following vulnerability has been resolved: smb: client: Fix use-after-free of network namespace. Recently, we got a customer report that CIFS triggers oops while reconnecting to a server. [0] The workload runs on Kubernetes, and some pods mount CIFS servers in non-root network namespaces. The problem rarely happened, but it was always while the pod was dying. The root cause is wrong reference counting for network namespace. CIFS uses kernel sockets, which do not hold refcnt of the netns that the socket belongs to. That means CIFS must ensure the socket is always freed before its netns; otherwise, use-after-free happens. The repro steps are roughly: 1. mount CIFS in a non-root netns 2. drop packets from the netns 3. destroy the netns 4. unmount CIFS We can reproduce the issue quickly with the script [1] below and see the splat [2] if CONFIG_NET_NS_REFCNT_TRACKER is enabled. When the socket is TCP, it is hard to guarantee the netns lifetime without holding refcnt due to async timers. Let's hold netns refcnt for each socket as done for SMC in commit 9744d2bf1976 ("smc: Fix use-after-free in tcp_write_timer_handler()."). Note that we need to move put_net() from cifs_put_tcp_session() to clean_demultiplex_info(); otherwise, __sock_create() still could touch a freed netns while cifsd tries to reconnect from cifs_demultiplex_thread(). Also, maybe_get_net() cannot be put just before __sock_create() because the code is not under RCU and there is a small chance that the same address happened to be reallocated to another netns.

An incorrectly configured PostgreSQL instance in the Appsmith image leads to remote command execution inside the Appsmith Docker container. The attacker must be able to access Appsmith, login to it, create a datasource, create a query against that datasource, and execute that query. analysis: 1. **分析是否与 namespace、cgroup、container 或容器隔离相关**: 该 CVE 描述中提到的是 Appsmith 的 PostgreSQL 实例配置错误,导致远程命令执行漏洞。问题的核心在于数据库配置不当,而非容器本身的 namespace、cgroup 或隔离机制的缺陷。因此,此 CVE 与容器隔离机制无直接关系。 2. **分析是否会影响其他容器或宿主机**: 根据描述,攻击者需要通过 Appsmith 的界面登录并执行特定操作(创建数据源和查询)才能触发漏洞。漏洞的影响范围被限制在 Appsmith 容器内部的 PostgreSQL 实例中。由于没有提到突破容器隔离的能力(如逃逸到宿主机或其他容器),因此可以认为此漏洞不会影响其他容器或宿主机。 3. **结论**: 条件 1 和 2 均不满足,返回 "N/A"。 **N/A** cve: ./data/2024/56xxx/CVE-2024-56783.json In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_socket: remove WARN_ON_ONCE on maximum cgroup level cgroup maximum depth is INT_MAX by default, there is a cgroup toggle to restrict this maximum depth to a more reasonable value not to harm performance. Remove unnecessary WARN_ON_ONCE which is reachable from userspace. analysis: 1. **分析是否与 namespace、cgroup、container 或容器、隔离相关** 该 CVE 提到 `cgroup` 的最大深度问题,并且涉及 `nft_socket` 和 `WARN_ON_ONCE` 的移除。`cgroup` 是 Linux 容器(如 Docker)实现资源限制和隔离的重要组成部分,因此该漏洞与 `cgroup` 直接相关,间接与容器的资源管理有关。 2. **分析是否会导致容器在运行时影响其他容器或宿主机** 虽然该漏洞涉及 `cgroup` 的最大深度配置,但其核心是移除一个从用户空间可触达的 `WARN_ON_ONCE`,这并不会直接导致容器突破隔离机制去影响其他容器或宿主机。不过,如果攻击者能够利用 `cgroup` 配置不当的问题(例如设置过深的层级),可能会间接影响系统性能或资源分配。但从描述来看,这种风险已被限制为性能影响,而非安全隔离破坏。 3. **结论** 条件 1 满足(与 `cgroup` 相关),条件 2 不满足(不会直接影响其他容器或宿主机的安全隔离)。因此,返回以下分析结果: - 与 `cgroup` 相关,可能间接影响容器的资源管理。 - 不会导致容器突破隔离机制影响其他容器或宿主机。 cve: ./data/2024/57xxx/CVE-2024-57977.json In the Linux kernel, the following vulnerability has been resolved: memcg: fix soft lockup in the OOM process A soft lockup issue was found in the product with about 56,000 tasks were in the OOM cgroup, it was traversing them when the soft lockup was triggered. watchdog: BUG: soft lockup - CPU#2 stuck for 23s!

For global OOM, call 'touch_softlockup_watchdog' per 1000 iterations to avoid this issue. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,这个 CVE 信息与 cgroup(控制组)直接相关。问题出现在 OOM(Out-of-Memory)处理过程中,具体是在 `mem_cgroup_scan_tasks` 函数中对大量任务进行遍历时触发了软锁死(soft lockup)。cgroup 是 Linux 内核中的一个关键特性,用于限制和隔离资源使用,包括内存管理。因此,该问题明确涉及 cgroup。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 是的,这个问题可能会导致容器运行时影响其他容器或宿主机。当大量的任务属于同一个 OOM cgroup 时,遍历这些任务可能导致 CPU 被长时间占用(软锁死),从而使系统无法及时响应其他任务。这种情况可能会影响同一宿主机上的其他容器或宿主机本身,尤其是当多个容器共享宿主机资源时。 3. **结论**: 根据上述分析,条件 1 和条件 2 均满足,因此返回以下分析结果: - 与 cgroup 和容器隔离机制相关。 - 可能会导致容器运行时影响其他容器或宿主机。 cve: ./data/2024/58xxx/CVE-2024-58088.json In the Linux kernel, the following vulnerability has been resolved: bpf: Fix deadlock when freeing cgroup storage The following commit bc235cdb423a ("bpf: Prevent deadlock from recursive bpf_task_storage_[get|delete]") first introduced deadlock prevention for fentry/fexit programs attaching on bpf_task_storage helpers. That commit also employed the logic in map free path in its v6 version. Later bpf_cgrp_storage was first introduced in c4bcfb38a95e ("bpf: Implement cgroup storage available to non-cgroup-attached bpf progs") which faces the same issue as bpf_task_storage, instead of its busy counter, NULL was passed to bpf_local_storage_map_free() which opened a window to cause deadlock: (acquiring local_storage->lock) _raw_spin_lock_irqsave+0x3d/0x50 bpf_local_storage_update+0xd1/0x460 bpf_cgrp_storage_get+0x109/0x130 bpf_prog_a4d4a370ba857314_cgrp_ptr+0x139/0x170 ? __bpf_prog_enter_recur+0x16/0x80 bpf_trampoline_6442485186+0x43/0xa4 cgroup_storage_ptr+0x9/0x20 (holding local_storage->lock) bpf_selem_unlink_storage_nolock.constprop.0+0x135/0x160 bpf_selem_unlink_storage+0x6f/0x110 bpf_local_storage_map_free+0xa2/0x110 bpf_map_free_deferred+0x5b/0x90 process_one_work+0x17c/0x390 worker_thread+0x251/0x360 kthread+0xd2/0x100 ret_from_fork+0x34/0x50 ret_from_fork_asm+0x1a/0x30 Progs: - A: SEC("fentry/cgroup_storage_ptr") - cgid (BPF_MAP_TYPE_HASH) Record the id of the cgroup the current task belonging to in this hash map, using the address of the cgroup as the map key. - cgrpa (BPF_MAP_TYPE_CGRP_STORAGE) If current task is a kworker, lookup the above hash map using function parameter @owner as the key to get its corresponding cgroup id which is then used to get a trusted pointer to the cgroup through bpf_cgroup_from_id().

Steps to reproduce: - Run A; - while (true) { Run B; Destroy B; } Fix this issue by passing its busy counter to the free procedure so it can be properly incremented before storage/smap locking. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关** 是的,这个 CVE 信息明确提到了 `bpf_cgrp_storage` 和 `BPF_MAP_TYPE_CGRP_STORAGE`,这些都是与 cgroup(控制组)密切相关的功能。此外,BPF 程序被用于操作 cgroup 存储,这表明该漏洞与 cgroup 的管理和使用直接相关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机** 这个漏洞主要涉及 BPF 程序在处理 cgroup 存储时可能导致死锁的问题。虽然它与 cgroup 相关,但问题的核心是 BPF 程序在特定情况下触发死锁,而不是直接影响容器隔离性或逃逸。因此,从描述来看,这个漏洞不会直接导致容器影响其他容器或宿主机的安全性,而是可能影响系统的稳定性(例如导致某些任务或线程卡住)。 3. **结论** 根据上述分析,条件 1 满足(与 cgroup 相关),但条件 2 不满足(不会直接影响其他容器或宿主机)。因此,返回以下内容: ``` 满足条件 1,不满足条件 2。 ``` cve: ./data/2024/5xxx/CVE-2024-5652.json In Docker Desktop on Windows before v4.31.0 allows a user in the docker-users group to cause a Windows Denial-of-Service through the exec-path Docker daemon config option in Windows containers mode. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息明确提到 Docker Desktop 和 Windows 容器模式。Docker 是一种容器化技术,因此该问题与容器和隔离机制相关。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 根据描述,攻击者可以通过 `exec-path` 配置选项导致 Windows 上的 Denial-of-Service (DoS)。这种行为会影响 Docker 守护进程,从而可能间接影响其他容器或宿主机的可用性。虽然没有明确说明可以直接控制宿主机或其他容器,但 DoS 攻击会降低整个系统的稳定性,因此可以认为它会对其他容器或宿主机产生间接影响。 **结论:满足条件 1 和 2。** cve: ./data/2024/6xxx/CVE-2024-6222.json In Docker Desktop before v4.29.0, an attacker who has gained access to the Docker Desktop VM through a container breakout can further escape to the host by passing extensions and dashboard related IPC messages. Docker Desktop v4.29.0 https://docs.docker.com/desktop/release-notes/#4290 fixes the issue on MacOS, Linux and Windows with Hyper-V backend. As exploitation requires "Allow only extensions distributed through the Docker Marketplace" to be disabled, Docker Desktop  v4.31.0 https://docs.docker.com/desktop/release-notes/#4310  additionally changes the default configuration to enable this setting by default. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与容器和隔离相关。它描述了 Docker Desktop 中的一个漏洞,攻击者可以通过容器逃逸访问 Docker Desktop 虚拟机,并进一步通过扩展和仪表板相关的 IPC 消息逃逸到宿主机。这直接影响了容器与宿主机之间的隔离。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机:** 是的,该漏洞会导致容器运行时影响宿主机。攻击者在获得对 Docker Desktop 虚拟机的访问权限后,可以进一步突破到宿主机,从而可能危及整个系统安全。虽然没有明确提到影响其他容器,但一旦攻击者控制了宿主机,理论上可以间接影响同一宿主机上的其他容器。 --- **结论:满足条件 1 和 2。** cve: ./data/2024/7xxx/CVE-2024-7387.json A flaw was found in openshift/builder. This vulnerability allows command injection via path traversal, where a malicious user can execute arbitrary commands on the OpenShift node running the builder container. When using the “Docker” strategy, executable files inside the privileged build container can be overridden using the `spec.source.secrets.secret.destinationDir` attribute of the `BuildConfig` definition. An attacker running code in a privileged container could escalate their permissions on the node running the container. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关:** 是的,该CVE与容器和隔离相关。问题发生在OpenShift的builder容器中,涉及到通过路径遍历进行命令注入,以及在特权容器中覆盖可执行文件的能力。这直接影响了容器的隔离性,特别是当使用“Docker”策略时。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机:** 是的,该漏洞可能导致运行时影响其他容器或宿主机。攻击者可以通过覆盖特权构建容器中的可执行文件,并利用`spec.source.secrets.secret.destinationDir`属性来执行任意命令,从而突破容器隔离,进一步可能危害到宿主机或其他共享同一节点的容器。 **结论:** 该CVE满足条件1和条件2。 cve: ./data/2024/7xxx/CVE-2024-7557.json A vulnerability was found in OpenShift AI that allows for authentication bypass and privilege escalation across models within the same namespace. When deploying AI models, the UI provides the option to protect models with authentication. However, credentials from one model can be used to access other models and APIs within the same namespace. The exposed ServiceAccount tokens, visible in the UI, can be utilized with oc --token={token} to exploit the elevated view privileges associated with the ServiceAccount, leading to unauthorized access to additional resources. analysis: 1. **是否与 namespace、cgroup、container 或容器、隔离相关:** 是的,该漏洞与 namespace 相关。描述中明确提到“同一 namespace”内的模型和 API 可以被跨模型访问,这表明问题发生在同一个 namespace 内的资源隔离机制上。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机:** 从描述来看,此漏洞主要涉及 OpenShift AI 的认证绕过和权限提升问题,集中在 ServiceAccount 和 UI 暴露的令牌上。虽然它允许攻击者访问同一 namespace 内的其他资源,但没有直接提到容器运行时或宿主机受到影响。因此,目前信息不足以证明它会直接影响其他容器或宿主机。 3. **结论:** 根据上述分析,条件 1 满足,条件 2 不满足,因此返回以下内容: **分析结果:** - 与 namespace 相关,涉及同一 namespace 内的资源隔离问题。 - 不会影响其他容器或宿主机。 cve: ./data/2024/7xxx/CVE-2024-7558.json JUJU_CONTEXT_ID is a predictable authentication secret. On a Juju machine (non-Kubernetes) or Juju charm container (on Kubernetes), an unprivileged user in the same network namespace can connect to an abstract domain socket and guess the JUJU_CONTEXT_ID value. This gives the unprivileged user access to the same information and tools as the Juju charm. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE信息提到“Juju charm container (on Kubernetes)”以及“unprivileged user in the same network namespace”,明确涉及到了容器和网络命名空间(network namespace),这些都是容器隔离机制的重要组成部分。因此,它与容器和隔离相关。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 根据描述,一个非特权用户可以通过猜测`JUJU_CONTEXT_ID`值,连接到抽象域套接字(abstract domain socket),从而获得与Juju charm相同的权限和工具访问。这表明,如果攻击者位于同一个网络命名空间内,他们可能利用此漏洞突破容器的隔离,访问或操控其他容器或宿主机上的资源。因此,这个漏洞确实可能导致容器运行时影响其他容器或宿主机。 ### 结论: - 条件1满足:与容器和隔离相关。 - 条件2满足:可能影响其他容器或宿主机。 cve: ./data/2024/7xxx/CVE-2024-7598.json A security issue was discovered in Kubernetes where a malicious or compromised pod could bypass network restrictions enforced by network policies during namespace deletion. The order in which objects are deleted during namespace termination is not defined, and it is possible for network policies to be deleted before the pods that they protect. This can lead to a brief period in which the pods are running, but network policies that should apply to connections to and from the pods are not enforced. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,此 CVE 信息与 namespace 和容器隔离相关。问题描述中提到,在 Kubernetes 中,当 namespace 被删除时,网络策略(Network Policies)可能在被保护的 Pod 之前被删除,导致网络限制在一段时间内无法生效。Namespace 是 Kubernetes 中用于隔离资源的核心概念之一,因此该问题直接影响到 namespace 的隔离性。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致恶意或受攻击的 Pod 在 namespace 删除期间绕过网络策略限制,从而访问其他 Pod 或宿主机上的资源。尽管这种影响是短暂的,但在此窗口期内,恶意 Pod 可能会利用未被强制执行的网络策略发起攻击或泄露数据。 **结论**:满足条件 1 和 2。 cve: ./data/2024/7xxx/CVE-2024-7771.json A vulnerability in the Dockerized version of mintplex-labs/anything-llm (latest, digest 1d9452da2b92) allows for a denial of service. Uploading an audio file with a very low sample rate causes the functionality responsible for transcribing it to crash the entire site instance. The issue arises from the localWhisper implementation, where resampling the audio file from 1 Hz to 16000 Hz quickly exceeds available memory, leading to the Docker instance being killed by the instance manager. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器相关。问题出现在 Docker 化版本的 mintplex-labs/anything-llm 应用中,且描述中提到由于内存耗尽导致 Docker 实例被实例管理器杀死,这表明问题发生在容器环境中,并且涉及到容器资源限制(如 cgroup 的内存限制)。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 在这种情况下,漏洞的影响仅限于单个容器实例(mintplex-labs/anything-llm)。虽然该容器可能会因为内存耗尽而被杀死,但没有证据表明此问题会直接影响其他容器或宿主机。如果容器的资源限制(如 cgroup)配置得当,这种资源耗尽的情况通常不会波及到宿主机或其他容器。 3. **结论**: 由于条件 1 满足,条件 2 不满足,因此返回以下分析结果: - 与容器和隔离相关:是。 - 是否影响其他容器或宿主机:否。 cve: ./data/2024/8xxx/CVE-2024-8037.json Vulnerable juju hook tool abstract UNIX domain socket. When combined with an attack of JUJU_CONTEXT_ID, any user on the local system with access to the default network namespace may connect to the @/var/lib/juju/agents/unit-xxxx-yyyy/agent.socket and perform actions that are normally reserved to a juju charm. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 该 CVE 提及了 "default network namespace",这表明问题涉及 Linux 命名空间(namespace),特别是网络命名空间。此外,Juju 是一个用于部署和管理应用程序的工具,通常在容器化环境中使用,因此可以间接关联到容器和隔离机制。 2. **分析是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 根据描述,任何拥有默认网络命名空间访问权限的用户都可以连接到特定的 UNIX 域套接字,并执行通常仅限于 Juju charm 的操作。如果此漏洞存在于容器化环境中,攻击者可能利用它从一个容器突破到宿主机或其他共享同一网络命名空间的容器。因此,该漏洞可能会对容器隔离产生影响,导致跨容器或容器对宿主机的潜在威胁。 **结论**:满足条件 1 和 2。 cve: ./data/2024/8xxx/CVE-2024-8038.json Vulnerable juju introspection abstract UNIX domain socket. An abstract UNIX domain socket responsible for introspection is available without authentication locally to network namespace users. This enables denial of service attacks. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关:** 该 CVE 提及了一个“abstract UNIX domain socket”用于 introspection(内省),并且明确提到它在“network namespace users”中可用。这表明问题与网络命名空间(network namespace)有关,而网络命名空间是 Linux 容器(如 Docker)实现隔离的重要组成部分之一。因此,这个问题与命名空间和隔离机制相关。 2. **分析是否会影响其他容器或宿主机:** 由于该漏洞允许“network namespace users”在没有身份验证的情况下访问抽象 UNIX 域套接字,攻击者可能利用此漏洞对目标系统进行拒绝服务(DoS)攻击。如果多个容器共享同一个网络命名空间(例如,在某些非默认配置下),那么一个容器中的恶意用户可能通过此漏洞影响其他容器或宿主机的稳定性。因此,这种漏洞有可能导致容器运行时影响其他容器或宿主机。 **结论:** 条件 1 和 2 都满足。 cve: ./data/2024/8xxx/CVE-2024-8060.json OpenWebUI version 0.3.0 contains a vulnerability in the audio API endpoint `/audio/api/v1/transcriptions` that allows for arbitrary file upload. The application performs insufficient validation on the `file.content_type` and allows user-controlled filenames, leading to a path traversal vulnerability. This can be exploited by an authenticated user to overwrite critical files within the Docker container, potentially leading to remote code execution as the root user. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞与容器相关。描述中明确提到漏洞影响的是一个运行在 Docker 容器中的应用,并且攻击者可以通过该漏洞覆盖容器内的关键文件。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 从描述来看,攻击者可以利用该漏洞在容器内执行任意代码(作为 root 用户)。如果容器没有正确配置隔离机制(例如共享宿主机的文件系统或其他资源),可能会进一步影响宿主机或其他容器。因此,该漏洞有可能间接影响宿主机或其他容器的安全性。 结论:满足条件 1 和 2。 cve: ./data/2024/8xxx/CVE-2024-8695.json A remote code execution (RCE) vulnerability via crafted extension description/changelog could be abused by a malicious extension in Docker Desktop before 4.34.2. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞涉及 Docker Desktop,而 Docker Desktop 是一个用于运行容器的平台。因此,它与容器技术及其隔离机制相关。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机**: 该漏洞描述提到的是通过恶意扩展(crafted extension)触发远程代码执行 (RCE)。如果攻击者利用此漏洞成功执行代码,可能会突破容器的隔离机制,从而影响其他容器或宿主机的安全性。因此,答案是可能的。 **结论**:满足条件1和条件2。 cve: ./data/2024/8xxx/CVE-2024-8696.json A remote code execution (RCE) vulnerability via crafted extension publisher-url/additional-urls could be abused by a malicious extension in Docker Desktop before 4.34.2. analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞与容器相关。描述中明确提到“Docker Desktop”,这是一个用于运行容器的平台,因此与容器技术直接相关。 2. **分析是否会导致容器在运行时影响其他容器或宿主机**: 该漏洞允许通过恶意扩展实现远程代码执行 (RCE),而此行为可能会影响 Docker Desktop 所管理的容器环境,甚至可能波及宿主机。如果攻击者利用此漏洞成功执行恶意代码,可能会突破容器的隔离机制,进而影响其他容器或宿主机的安全性。 3. **结论**: 条件 1 和 2 均满足,因此返回分析结果而非 "N/A"。 cve: ./data/2024/9xxx/CVE-2024-9407.json A vulnerability exists in the bind-propagation option of the Dockerfile RUN --mount instruction. The system does not properly validate the input passed to this option, allowing users to pass arbitrary parameters to the mount instruction. This issue can be exploited to mount sensitive directories from the host into a container during the build process and, in some cases, modify the contents of those mounted files. Even if SELinux is used, this vulnerability can bypass its protection by allowing the source directory to be relabeled to give the container access to host files. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该漏洞与容器和隔离机制直接相关。漏洞存在于 Dockerfile 的 `RUN --mount` 指令中的 `bind-propagation` 选项,涉及容器构建过程中主机目录被挂载到容器内的行为。这直接影响了容器与宿主机之间的隔离性。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器在构建过程中访问并修改宿主机上的敏感目录和文件。通过利用此漏洞,攻击者可以绕过 SELinux 等安全机制,对宿主机文件系统进行未授权的访问和修改。这种行为可能进一步影响其他容器的运行环境,甚至导致宿主机被完全控制。 结论:该 CVE 满足条件 1 和条件 2。 cve: ./data/2024/9xxx/CVE-2024-9676.json A vulnerability was found in Podman, Buildah, and CRI-O. A symlink traversal vulnerability in the containers/storage library can cause Podman, Buildah, and CRI-O to hang and result in a denial of service via OOM kill when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). The containers/storage library will read /etc/passwd inside the container, but does not properly validate if that file is a symlink, which can be used to cause the library to read an arbitrary file on the host. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 信息与 namespace 和容器相关。具体来说,问题出现在容器的存储库 `containers/storage` 中,涉及用户命名空间 (`user namespace`) 的使用 (`--userns=auto`)。此外,漏洞利用了符号链接(symlink)遍历的问题,可能影响宿主机文件系统的隔离性。 2. **是否会导致容器(如 Docker 等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器运行时影响宿主机。由于 `containers/storage` 库没有正确验证 `/etc/passwd` 是否为符号链接,攻击者可以通过恶意容器镜像读取宿主机上的任意文件,从而破坏隔离性。虽然这主要是一个拒绝服务 (DoS) 漏洞(通过 OOM kill),但潜在的文件系统访问风险也可能导致进一步的安全问题。 因此,根据以上分析,条件 1 和 2 均满足。 cve: ./data/2025/0xxx/CVE-2025-0113.json A problem with the network isolation mechanism of the Palo Alto Networks Cortex XDR Broker VM allows attackers unauthorized access to Docker containers from the host network used by Broker VM.

The commit 3a5a6d0c2b03 ("cpuset: don't nest cgroup_mutex inside get_online_cpus()") made cpuset_hotplug_workfn asynchronous, This change involves calling flush_work(), which can create a multiple processes circular locking dependency that involve cgroup_mutex, potentially leading to a deadlock. To avoid deadlock. the commit 76bb5ab8f6e3 ("cpuset: break kernfs active protection in cpuset_write_resmask()") added 'kernfs_break_active_protection' in the cpuset_write_resmask. This could lead to this warning. After the commit 2125c0034c5d ("cgroup/cpuset: Make cpuset hotplug processing synchronous"), the cpuset_write_resmask no longer needs to wait the hotplug to finish, which means that concurrent hotplug and cpuset operations are no longer possible. Therefore, the deadlock doesn't exist anymore and it does not have to 'break active protection' now. To fix this warning, just remove kernfs_break_active_protection operation in the 'cpuset_write_resmask'. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该CVE信息与`cgroup`和`cpuset`子系统直接相关。`cgroup`(控制组)是Linux内核中用于限制、控制和隔离进程组资源(如CPU、内存、磁盘I/O等)的重要机制,广泛应用于容器技术(如Docker、Kubernetes等)以实现资源隔离。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机** 从描述来看,该漏洞涉及`kernfs_break_active_protection`操作导致的警告问题。虽然这是一个潜在的内核问题,但它主要影响`cgroup`子系统的稳定性和一致性,而不是直接破坏容器之间的隔离性或对宿主机的安全造成威胁。具体来说: - 该问题可能导致内核在处理`cpuset.cpus`文件时出现竞争条件(concurrency issue),从而触发警告。 - 不过,这种警告并不会直接导致容器逃逸(container escape)或其他安全风险,而是可能引发内核的不稳定行为(如死锁或崩溃),间接影响整个系统的可靠性。 3. **结论** 由于该CVE与`cgroup`相关,并可能间接影响容器运行时的稳定性,因此满足条件1和条件2的部分要求。然而,它并不直接导致容器逃逸或直接影响其他容器或宿主机的安全性。 cve: ./data/2025/21xxx/CVE-2025-21659.json In the Linux kernel, the following vulnerability has been resolved: netdev: prevent accessing NAPI instances from another namespace The NAPI IDs were not fully exposed to user space prior to the netlink API, so they were never namespaced.

Specifically, it discusses the improper handling of network devices and UDP sockets across different network namespaces (`src_net` and `dev_net(dev)`). - The issue arises when a network namespace (`src_net`) is removed, but the associated device (`gtp0`) remains alive in another namespace (`dev_net(dev)`), leading to a reference count mismatch and a kernel warning. - This indicates that the vulnerability is directly related to namespaces, which are fundamental to container isolation. 2. **Impact on containers or host:** - The described vulnerability does not appear to allow privilege escalation, arbitrary code execution, or direct interaction between containers or with the host system. Instead, it is a bug in resource management within network namespaces. - However, if improperly handled, such issues could theoretically lead to instability in containers or the host if the network namespace teardown process is disrupted. In this specific case, the impact seems limited to a kernel warning due to a reference count mismatch. - While the vulnerability does not directly compromise container isolation, it could indirectly affect the stability of containers using network namespaces. 3. **Conclusion:** - Based on the analysis, the CVE is related to namespaces and could have an indirect impact on container stability. - It does not explicitly allow breaking out of containers or affecting other containers or the host in a security-critical manner. **Final Answer:** The CVE is related to namespaces and could indirectly impact container stability, but it does not directly compromise container isolation or allow affecting other containers or the host. cve: ./data/2025/21xxx/CVE-2025-21771.json In the Linux kernel, the following vulnerability has been resolved: sched_ext: Fix incorrect autogroup migration detection scx_move_task() is called from sched_move_task() and tells the BPF scheduler that cgroup migration is being committed. sched_move_task() is used by both cgroup and autogroup migrations and scx_move_task() tried to filter out autogroup migrations by testing the destination cgroup and PF_EXITING but this is not enough. In fact, without explicitly tagging the thread which is doing the cgroup migration, there is no good way to tell apart scx_move_task() invocations for racing migration to the root cgroup and an autogroup migration. This led to scx_move_task() incorrectly ignoring a migration from non-root cgroup to an autogroup of the root cgroup triggering the following warning: WARNING: CPU: 7 PID: 1 at kernel/sched/ext.c:3725 scx_cgroup_can_attach+0x196/0x340 ...

After the change, scx_move_task() is called only for cgroup migrations and renamed to scx_cgroup_move_task(). analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关** 是的,该CVE信息与cgroup相关。描述中提到`scx_move_task()`函数用于处理cgroup和autogroup迁移,并且涉及cgroup迁移时的检测问题。cgroup是Linux内核中用于限制、控制和隔离进程组资源使用的重要机制,广泛应用于容器技术(如Docker)中以实现资源隔离。 2. **是否会导致容器在运行时影响其他容器或宿主机** 从描述来看,该漏洞主要导致一个警告(WARNING)被触发,而不是直接的安全漏洞或资源泄露问题。虽然它涉及cgroup迁移的检测逻辑,但并未提到可能导致容器逃逸、资源滥用或其他容器的影响。因此,该问题更倾向于是一个功能性缺陷,而非安全漏洞,不会直接影响其他容器或宿主机的安全性。 3. **结论** 条件1满足,条件2不满足,因此返回分析结果而非"N/A"。 cve: ./data/2025/21xxx/CVE-2025-21834.json In the Linux kernel, the following vulnerability has been resolved: seccomp: passthrough uretprobe systemcall without filtering When attaching uretprobes to processes running inside docker, the attached process is segfaulted when encountering the retprobe. The reason is that now that uretprobe is a system call the default seccomp filters in docker block it as they only allow a specific set of known syscalls. This is true for other userspace applications which use seccomp to control their syscall surface. Since uretprobe is a "kernel implementation detail" system call which is not used by userspace application code directly, it is impractical and there's very little point in forcing all userspace applications to explicitly allow it in order to avoid crashing tracked processes. Pass this systemcall through seccomp without depending on configuration. Note: uretprobe is currently only x86_64 and isn't expected to ever be supported in i386. [kees: minimized changes for easier backporting, tweaked commit log] analysis: 1. **分析是否与namespace、cgroup、container或者容器、隔离相关** 是的,该CVE信息与容器和隔离相关。具体来说,问题出现在使用 `uretprobe` 调试工具时,当将其附加到运行在 Docker 容器中的进程时,由于默认的 seccomp 过滤器阻止了 `uretprobe` 系统调用,导致目标进程崩溃(段错误)。这表明问题涉及容器的默认安全机制(seccomp)以及其对系统调用的限制。 2. **分析是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机** 该漏洞本身并不会直接导致一个容器影响其他容器或宿主机。问题的核心在于调试工具 `uretprobe` 的系统调用被默认的 seccomp 配置所阻止,从而导致调试的目标进程崩溃。这种崩溃仅限于被调试的进程本身,并不会扩散到其他容器或宿主机。然而,如果用户明确配置 seccomp 规则以允许 `uretprobe`,可能会间接降低容器的安全性,但这并非此 CVE 的直接后果。 3. **结论** 条件1满足,条件2不满足,因此返回以下分析结果: - 与 namespace、cgroup、container 或者容器、隔离相关:是。 - 是否会导致容器影响其他容器或宿主机:否。 cve: ./data/2025/22xxx/CVE-2025-22089.json In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Don't expose hw_counters outside of init net namespace Commit 467f432a521a ("RDMA/core: Split port and device counter sysfs attributes") accidentally almost exposed hw counters to non-init net namespaces.

However the real problem is that hw counters should never been exposed outside of the non-init net namespace. Fix this by saving the index of the corresponding attribute group (it might be 1 or 2 depending on the presence of driver-specific attributes) and zeroing the pointer to hw_counters group for compat devices during the initialization. With this fix applied hw_counters are not available in a non-init net namespace: find /sys/class/infiniband/mlx4_0/ -name hw_counters /sys/class/infiniband/mlx4_0/ports/1/hw_counters /sys/class/infiniband/mlx4_0/ports/2/hw_counters /sys/class/infiniband/mlx4_0/hw_counters ip netns add foo ip netns exec foo bash find /sys/class/infiniband/mlx4_0/ -name hw_counters analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关** - 该 CVE 涉及到网络命名空间(net namespace)的问题。具体来说,硬件计数器(hw_counters)被错误地暴露在非初始网络命名空间中,这可能导致内存损坏或崩溃。因此,这个漏洞与 Linux 命名空间(namespace)直接相关。 2. **分析是否会导致容器(如 Docker)运行时影响其他容器或宿主机** - 由于问题涉及到网络命名空间,而容器通常使用独立的网络命名空间来实现网络隔离,如果 hw_counters 被错误地暴露给非初始网络命名空间,攻击者可能利用此漏洞访问或修改宿主机或其他容器的资源。尽管当前的修复已经阻止了 hw_counters 在非初始网络命名空间中的访问,但在未修复的情况下,这种行为可能会导致容器逃逸或对宿主机产生影响。 3. **结论** - 条件 1 和条件 2 都满足,因此返回以下分析结果: - 该 CVE 与 namespace 相关,且可能在特定情况下影响容器的隔离性,导致容器逃逸或影响宿主机的安全性。 cve: ./data/2025/23xxx/CVE-2025-23211.json Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. A Jinja2 SSTI vulnerability allows any user to execute commands on the server. In the case of the provided Docker Compose file as root. This vulnerability is fixed in 1.5.24. analysis: 1. 该 CVE 信息与 namespace、cgroup、container 或容器隔离机制无直接关系。问题的核心是一个 Jinja2 SSTI(Server-Side Template Injection)漏洞,它允许用户在服务器上执行命令。 2. 尽管这是一个命令执行漏洞,并且提到 Docker Compose 文件,但它本身并不直接影响容器的隔离性或导致一个容器影响其他容器或宿主机。此漏洞的影响范围取决于运行 Tandoor Recipes 应用程序的容器权限配置。如果容器以 root 用户运行并且没有适当的隔离措施,攻击者可能利用该漏洞突破容器并影响宿主机。但这更多是由于错误的容器配置(例如以 root 运行容器)而非漏洞本身的特性。 3. 综上所述,虽然此漏洞严重,但其本质是一个应用程序层面的问题,而不是容器或隔离机制的漏洞。 **结论:N/A** cve: ./data/2025/27xxx/CVE-2025-27519.json Cognita is a RAG (Retrieval Augmented Generation) Framework for building modular, open source applications for production by TrueFoundry. A path traversal issue exists at /v1/internal/upload-to-local-directory which is enabled when the Local env variable is set to true, such as when Cognita is setup using Docker. Because the docker environment sets up the backend uvicorn server with auto reload enabled, when an attacker overwrites the /app/backend/__init__.py file, the file will automatically be reloaded and executed. This allows an attacker to get remote code execution in the context of the Docker container. This vulnerability is fixed in commit a78bd065e05a1b30a53a3386cc02e08c317d2243. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 信息明确提到 Cognita 在 Docker 环境中运行时存在漏洞。具体来说,当 `Local` 环境变量设置为 `true` 时,路径遍历问题会导致攻击者能够覆盖 `/app/backend/__init__.py` 文件,并触发远程代码执行 (RCE)。这表明该问题与容器(Docker)的运行环境直接相关。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机:** 根据描述,攻击者可以利用此漏洞在容器内实现远程代码执行。然而,这种 RCE 的影响范围仅限于当前容器上下文。没有明确提到该漏洞能够突破容器隔离机制(如 namespace 或 cgroup),进而影响其他容器或宿主机。因此,从现有信息来看,该漏洞不会直接影响其他容器或宿主机,除非攻击者进一步利用其他漏洞或配置错误来逃逸容器。 **结论:** - 满足条件 1(与容器相关)。 - 不满足条件 2(不会直接影响其他容器或宿主机)。 **最终结果:** N/A cve: ./data/2025/27xxx/CVE-2025-27615.json umatiGateway is software for connecting OPC Unified Architecture servers with an MQTT broker utilizing JSON messages. The user interface may possibly be publicly accessible with umatiGateway's provided docker-compose file. With this access, the configuration can be viewed and altered. Commit 5d81a3412bc0051754a3095d89a06d6d743f2b16 uses `127.0.0.1:8080:8080` to limit access to the local network. For those who are unable to use this proposed patch, a firewall on Port 8080 may block remote access, but the workaround may not be perfect because Docker may also bypass a firewall by its iptable based rules for port forwarding. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,此 CVE 信息与容器相关。具体来说,问题出现在 umatiGateway 提供的 `docker-compose` 文件中,该文件配置了容器的服务暴露方式。由于容器的用户界面可能被公开访问,这表明容器的网络配置或隔离设置存在问题。 2. **分析是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 有可能。如果攻击者通过公开访问的用户界面修改了配置,可能会导致以下后果: - 攻击者可以查看或篡改敏感配置,从而影响容器的正常运行。 - 如果容器以不安全的方式配置了网络(例如,绕过防火墙规则),攻击者可能利用此漏洞进一步访问宿主机或其他容器。 因此,此 CVE 可能会影响容器的隔离性,并间接影响宿主机或其他容器的安全性。 **结论**:满足条件 1 和 2,存在与容器隔离相关的安全风险。 cve: ./data/2025/2xxx/CVE-2025-2312.json A flaw was found in cifs-utils. When trying to obtain Kerberos credentials, the cifs.upcall program from the cifs-utils package makes an upcall to the wrong namespace in containerized environments. This issue may lead to disclosing sensitive data from the host's Kerberos credentials cache. analysis: 1. **是否与 namespace、cgroup、container 或容器、隔离相关**: 是的,该 CVE 信息明确提到问题发生在容器化环境中,并且涉及命名空间(namespace)的错误使用。具体来说,`cifs.upcall` 程序在容器中尝试获取 Kerberos 凭据时,错误地向上调用到了主机的命名空间,而不是容器的命名空间。 2. **是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器内的程序访问到宿主机的 Kerberos 凭据缓存,从而泄露敏感数据。这表明容器的隔离性被破坏,攻击者可能利用此漏洞从容器内获取宿主机的敏感信息。 3. **结论**: 条件 1 和条件 2 均满足,因此返回上述分析内容。 cve: ./data/2025/30xxx/CVE-2025-30162.json Cilium is a networking, observability, and security solution with an eBPF-based dataplane. For Cilium users who use Gateway API for Ingress for some services and use LB-IPAM or BGP for LB Service implementation and use network policies to block egress traffic from workloads in a namespace to workloads in other namespaces, egress traffic from workloads covered by such network policies to LoadBalancers configured by `Gateway` resources will incorrectly be allowed. LoadBalancer resources not deployed via a Gateway API configuration are not affected by this issue. This issue affects: Cilium v1.15 between v1.15.0 and v1.15.14 inclusive, v1.16 between v1.16.0 and v1.16.7 inclusive, and v1.17 between v1.17.0 and v1.17.1 inclusive. This issue is fixed in Cilium v1.15.15, v1.16.8, and v1.17.2. A Clusterwide Cilium Network Policy can be used to work around this issue for users who are unable to upgrade. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,这个 CVE 信息与 namespace 和容器隔离相关。问题描述中提到网络策略(network policies)用于阻止某个命名空间(namespace)中的工作负载(workloads)到其他命名空间中的工作负载的出口流量(egress traffic)。这表明它涉及到基于命名空间的网络隔离。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 不会直接影响其他容器或宿主机。此漏洞导致的问题是特定的网络策略未能正确阻止从某些工作负载到通过 `Gateway` 资源配置的 LoadBalancer 的出口流量。这种行为可能会破坏预期的网络隔离,但并不会直接导致容器逃逸或影响宿主机的安全性。 3. **结论**: 条件 1 满足,条件 2 不满足,因此返回分析结果而不是 "N/A"。 cve: ./data/2025/30xxx/CVE-2025-30206.json Dpanel is a Docker visualization panel system which provides complete Docker management functions. The Dpanel service contains a hardcoded JWT secret in its default configuration, allowing attackers to generate valid JWT tokens and compromise the host machine. This security flaw allows attackers to analyze the source code, discover the embedded secret, and craft legitimate JWT tokens. By forging these tokens, an attacker can successfully bypass authentication mechanisms, impersonate privileged users, and gain unauthorized administrative access. Consequently, this enables full control over the host machine, potentially leading to severe consequences such as sensitive data exposure, unauthorized command execution, privilege escalation, or further lateral movement within the network environment. This issue is patched in version 1.6.1. A workaround for this vulnerability involves replacing the hardcoded secret with a securely generated value and load it from secure configuration storage. analysis: 1. 该 CVE 信息与 namespace、cgroup、container 或容器隔离机制无直接关系。问题的核心是 Dpanel 服务中硬编码的 JWT 密钥,这属于应用层的安全配置问题,而非容器或隔离技术本身的漏洞。 2. 该 CVE 可能会导致攻击者在成功利用后影响宿主机,但其本身并不会直接影响其他容器。由于攻击者可以通过伪造的 JWT 令牌获得对 Dpanel 的完全控制,而 Dpanel 是一个用于管理 Docker 的工具,因此攻击者可能间接通过 Dpanel 操控宿主机上的其他容器或宿主机本身。 结论:满足条件 2,返回分析结果。 cve: ./data/2025/32xxx/CVE-2025-32754.json In jenkins/ssh-agent Docker images 6.11.1 and earlier, SSH host keys are generated on image creation for images based on Debian, causing all containers based on images of the same version use the same SSH host keys, allowing attackers able to insert themselves into the network path between the SSH client (typically the Jenkins controller) and SSH build agent to impersonate the latter. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关:** 是的,该 CVE 与容器和隔离相关。问题发生在基于 Debian 的 Jenkins/ssh-agent Docker 镜像中,SSH 主机密钥在镜像创建时生成,而不是在容器启动时动态生成。这导致所有基于相同版本镜像的容器共享相同的 SSH 主机密钥,破坏了容器之间的隔离性。 2. **是否会导致容器(例如 Docker)在运行时影响其他容器或宿主机:** 是的,此漏洞可能导致容器影响其他容器的安全性。由于所有容器共享相同的 SSH 主机密钥,攻击者可以通过网络插入攻击(如中间人攻击)冒充 SSH 构建代理,从而破坏通信的安全性。虽然它本身不会直接影响宿主机,但通过破坏容器间的通信安全,可能会间接影响宿主机上的其他服务或资源。 因此,条件 1 和 2 均满足。 cve: ./data/2025/32xxx/CVE-2025-32755.json In jenkins/ssh-slave Docker images based on Debian, SSH host keys are generated on image creation for images based on Debian, causing all containers based on images of the same version use the same SSH host keys, allowing attackers able to insert themselves into the network path between the SSH client (typically the Jenkins controller) and SSH build agent to impersonate the latter. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE明确提到了Docker镜像和容器。问题发生在基于Debian的`jenkins/ssh-slave` Docker镜像中,由于SSH主机密钥在镜像构建时生成,所有基于同一版本镜像创建的容器共享相同的SSH主机密钥。这表明该问题与容器技术及其隔离机制直接相关。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞会导致安全风险。由于所有基于相同镜像的容器共享相同的SSH主机密钥,攻击者可以通过网络中间人攻击(MITM)冒充SSH构建代理,从而破坏容器之间的通信安全性。虽然此漏洞本身不会直接影响宿主机,但它会削弱容器间的隔离性,使得攻击者能够更容易地渗透到其他容器或整个CI/CD管道中。 **结论**:满足条件1和条件2,分析完毕。 cve: ./data/2025/32xxx/CVE-2025-32955.json Harden-Runner is a CI/CD security agent that works like an EDR for GitHub Actions runners. Versions from 0.12.0 to before 2.12.0 are vulnerable to `disable-sudo` bypass. Harden-Runner includes a policy option `disable-sudo` to prevent the GitHub Actions runner user from using sudo. This is implemented by removing the runner user from the sudoers file. However, this control can be bypassed as the runner user, being part of the docker group, can interact with the Docker daemon to launch privileged containers or access the host filesystem. This allows the attacker to regain root access or restore the sudoers file, effectively bypassing the restriction. This issue has been patched in version 2.12.0. analysis: 1. **分析是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 信息与容器和隔离相关。问题的核心在于 Harden-Runner 的 `disable-sudo` 功能被绕过,原因是 GitHub Actions 运行器用户属于 `docker` 组,能够与 Docker 守护进程交互,从而启动特权容器或访问宿主机文件系统。这表明问题涉及容器技术以及其与宿主机之间的隔离机制。 2. **分析是否会导致容器(如 Docker)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器运行时影响宿主机。由于攻击者可以利用 Docker 守护进程启动特权容器或直接访问宿主机文件系统,这种行为可能会破坏容器与宿主机之间的隔离性,进而允许攻击者获得宿主机的 root 权限或恢复 `sudoers` 文件,最终完全控制宿主机。 **结论**:满足条件 1 和 2。 cve: ./data/2025/3xxx/CVE-2025-3047.json When running the AWS Serverless Application Model Command Line Interface (SAM CLI) build process with Docker and symlinks are included in the build files, the container environment allows a user to access privileged files on the host by leveraging the elevated permissions granted to the tool. A user could leverage the elevated permissions to access restricted files via symlinks and copy them to a more permissive location on the container. Users should upgrade to v1.133.0 or newer and ensure any forked or derivative code is patched to incorporate the new fixes. analysis: 1. **是否与namespace、cgroup、container或者容器、隔离相关**: 是的,该CVE与容器和隔离相关。问题发生在使用AWS SAM CLI通过Docker构建应用的过程中,涉及容器环境中的权限提升和文件访问问题。 2. **是否会导致容器(例如Docker等)在运行时影响其他容器或宿主机**: 是的,该漏洞可能导致容器内的用户通过符号链接(symlinks)访问宿主机上的特权文件。这种行为破坏了容器与宿主机之间的隔离性,可能会对宿主机或其他共享宿主机资源的容器造成影响。 因此,该CVE满足条件1和条件2。 cve: ./data/2025/3xxx/CVE-2025-3048.json After completing a build with AWS Serverless Application Model Command Line Interface (SAM CLI) which include symlinks, the content of those symlinks are copied to the cache of the local workspace as regular files or directories. As a result, a user who does not have access to those symlinks outside of the Docker container would now have access via the local workspace. Users should upgrade to version 1.134.0 and ensure any forked or derivative code is patched to incorporate the new fixes. After upgrading, users must re-build their applications using the sam build --use-container to update the symlinks. analysis: 1. **是否与 namespace、cgroup、container 或者容器、隔离相关**: 是的,该 CVE 与容器相关。问题描述中明确提到 AWS SAM CLI 在构建过程中将符号链接(symlinks)的内容复制到本地工作区缓存中,并且这些内容在 Docker 容器内被处理。 2. **是否会导致容器(例如 Docker 等)在运行时影响其他容器或宿主机**: 是的,可能会对隔离性造成影响。虽然该漏洞本身不会直接破坏容器的隔离机制(如 namespace 或 cgroup),但它导致了原本无法访问的符号链接内容可以通过容器内的操作暴露到本地工作区。这可能使得攻击者通过特定方式获取到原本受限的文件内容,从而间接影响宿主机或其他容器的安全性。 **结论**:满足条件 1 和 2。
