远程主机会受到 GLSA-202401-31 中所述漏洞的影响（containerd：多个漏洞）

  - containerd 是容器运行时。在 1.4.8 和 1.5.4 之前的 containerd 版本中发现一个错误，在这些版本中，提取特别构建的容器映像会更改主机文件系统中现有文件的 Unix 文件权限。文件权限变更可拒绝文件预期所有者的访问、扩大对其他文件的访问权限，或设置 setuid、setgid 和 sticky 等扩展位。此错误不会直接允许在没有其他合作进程的情况下读取、修改或执行文件。此错误已在 containerd 1.5.4 和 1.4.8 中修复。作为变通方案，确保用户只从受信任的来源提取图像。SELinux 和 AppArmor 等 Linux 安全模块 (LSM) 可通过防止 containerd 与特定文件交互的策略和配置文件，来限制可能受此错误影响的文件。(CVE-2021-32760)

  - containerd 是一个强调简易性、稳定性和可移植性的开源容器运行时。
    在 containerd 中发现一个错误，其中容器根目录和某些插件的限制权限不足，非特权 Linux 用户可利用此漏洞，遍历目录内容并执行程序。当容器包含的可执行程序具有扩展权限位（如 setuid）时，非特权 Linux 用户可发现并执行这些程序。当主机上的非特权 Linux 用户与容器内文件所有者或群组的 UID 冲突时，主机上的非特权 Linux 用户可发现、读取和修改这些文件。此漏洞已在 containerd 1.4.11 和 containerd 1.5.7 中修复。用户应在这些版本发布后进行相应更新，并可通过重新启动容器或更新目录权限来缓解此漏洞。无法更新的用户应限制受信任的用户访问主机的权限。更新绑定目录的容器的目录权限。(CVE-2021-41103)

  - containerd 是一个开源容器运行时。在 containerd 的 CRI 实现中发现一个缺陷，用户可在其中耗尽主机上的内存。在 CRI 流服务器中，如果请求 TTY，则会启动一个 go 例程来处理终端大小调整事件。如果用户的进程因错误命令等原因无法启动，则 go 例程将在没有接收器的情况下等待发送，从而导致内存泄漏。
    Kubernetes 和 crictl 均可配置为使用 containerd 的 CRI 实现，流服务器尅用于处理容器 IO。此错误已在 containerd 1.6.12 和 1.5.16 中修复。用户应更新到这些版本以解决该问题。无法升级的用户应确保仅使用受信任的映像和命令，并且只有受信任的用户才有权限在运行中的容器中执行命令。(CVE-2022-23471)

  - containerd 指容器运行时，可用作 Linux 和 Windows 的后台程序。在 containerd 1.6.1、 1.5.10 和 1.14.12 之前版本中发现一个错误，其中在 Linux 上通过 containerd 的 CRI 实现启动的容器可以使用特制的映像配置访问主机上任意文件和目录的只读副本。这可能会绕过对容器设置的任何基于策略的实施（包括 Kubernetes Pod 安全策略）并暴露潜在的敏感信息。
    Kubernetes 和 crictl 均可配置为使用 containerd 的 CRI 实现。此错误已在 containerd 1.6.1、1.5.10和 1.4.12 中修复。用户应更新到这些版本以解决该问题。
    (CVE-2022-23648)

  - Moby 是 Docker 创建的开源项目，用于实现并加快软件容器化。在低于 20.10.14 版本的 Moby (Docker Engine) 中发现一个错误，其中容器以非空、可继承的 Linux 进程功能启动，从而创建非典型 Linux 环境，并使具有可继承文件功能的程序在 `execve(2)` 期间将这些功能提升至允许的集。通常，当可执行程序已指定允许的文件功能时，无特权用户和进程就可以执行这些程序并获得符合边界集规定的指定文件功能。由于存在这一错误，包含具有可继承文件功能的可执行程序的容器允许无特权用户和进程额外获得此类符合容器边界集规定的可继承文件功能。使用 Linux 用户和群组在容器内执行特权分离的容器受此错误的影响最大。此错误不影响容器安全沙盒，因为可继承集包含的功能绝不会多于容器边界集中包含的功能。此错误已在 Moby (Docker Engine) 中修复 20.10.14。您应当停止、删除并重新创建正在运行的容器，以便重置可继承功能。此补丁更改了 Moby (Docker Engine) 行为，以便在启动容器时创建更典型的 Linux 环境。有一种解决办法是，修改容器的入口点，以使用“capsh(1)”等实用工具，在主进程启动之前终止可继承功能。(CVE-2022-24769)

  - containerd 是一个开源容器运行时。在 containerd 的 CRI 实现中发现一个缺陷，即在“ExecSync”API 调用期间，容器内的程序可导致 containerd 后台程序无限制地消耗内存。这可能导致 containerd 消耗计算机上的所有可用内存，从而拒绝为其他合法工作负载提供服务。Kubernetes 和 crictl 均可配置为使用 containerd 的 CRI 实现；运行探测或通过 exec 设施执行进程时，可使用“ExecSync”。此错误已在 containerd 1.6.6 和 1.5.13 中修复。用户应更新到这些版本以解决该问题。无法升级的用户应确保仅使用受信任的图像和命令。 (CVE-2022-31030)

请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

    在 containerd 中发现一个错误，其中通过 containerd 的 CRI 实现启动的容器可以使用特制的映像配置访问主机上任意文件和目录的只读副本。这可能会绕过对容器设置的任何基于策略的实施（包括 Kubernetes Pod 安全策略）并暴露潜在的敏感信息。Kubernetes 和 crictl 均可配置为使用 containerd 的 CRI 实现。(CVE-2022-23648)

    Moby 是 Docker 创建的一个开源项目，用于实现和加速软件容器化。在低于 20.10.14 版本的 Moby (Docker Engine) 中发现一个错误，其中容器以非空、可继承的 Linux 进程功能启动，从而创建非典型 Linux 环境，并使具有可继承文件功能的程序在 `execve(2)` 期间将这些功能提升至允许的集。通常，当可执行程序已指定允许的文件功能时，无特权用户和进程就可以执行这些程序并获得符合边界集规定的指定文件功能。由于存在这一错误，包含具有可继承文件功能的可执行程序的容器允许无特权用户和进程额外获得此类符合容器边界集规定的可继承文件功能。使用 Linux 用户和群组在容器内执行特权分离的容器受此错误的影响最大。此错误不影响容器安全沙盒，因为可继承集包含的功能绝不会多于容器边界集中包含的功能。此错误已在 Moby (Docker Engine) 中修复 20.10.14。您应当停止、删除并重新创建正在运行的容器，以便重置可继承功能。此补丁更改了 Moby (Docker Engine) 行为，以便在启动容器时创建更典型的 Linux 环境。有一种解决办法是，修改容器的入口点，以使用“capsh(1)”等实用工具，在主进程启动之前终止可继承功能。(CVE-2022-24769)

    在 containerd 的 CRI 实现中发现一个缺陷，其中容器内的程序可导致 containerd 后台程序在调用 ExecSync API 期间无边界地消耗内存。这可能导致 containerd 消耗计算机上的所有可用内存，从而拒绝为其他合法工作负载提供服务。
    Kubernetes 和 crictl 均可配置为使用 containerd 的 CRI 实现；运行探测或通过 exec 设施执行进程时，可使用 ExecSync。 (CVE-2022-31030)

According to the versions of the docker-engine package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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. (CVE-2022-24769)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of containerd installed on the remote host is prior to 1.4.13-3. The version of docker installed on the remote host is prior to 20.10.13-2. The version of ecs-init installed on the remote host is prior to 1.61.1-1. The version of runc installed on the remote host is prior to 1.0.3-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ECS-2022-001 advisory.

    A bug was found in containerd where containers launched through containerd's CRI implementation with a     specially-crafted image configuration could gain access to read-only copies of arbitrary files and     directories on the host. This may bypass any policy-based enforcement on container setup (including a     Kubernetes Pod Security Policy) and expose potentially sensitive information. Kubernetes and crictl can     both be configured to use containerd's CRI implementation. (CVE-2022-23648)

    A bug was found in containerd's CRI implementation where programs inside a container can cause the     containerd daemon to consume memory without bound during invocation of the ExecSync API. This can cause     containerd to consume all available memory on the computer, denying service to other legitimate workloads.
    Kubernetes and crictl can both be configured to use containerd's CRI implementation; ExecSync may be used     when running probes or when executing processes via an exec facility. (CVE-2022-31030)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the docker-engine packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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. (CVE-2020-15157)

  - containerd is a container runtime. A bug was found in containerd versions prior to 1.4.8 and 1.5.4 where     pulling and extracting a specially-crafted container image can result in Unix file permission changes for     existing files in the host's filesystem. Changes to file permissions can deny access to the expected owner     of the file, widen access to others, or set extended bits like setuid, setgid, and sticky. This bug does     not directly allow files to be read, modified, or executed without an additional cooperating process. This     bug has been fixed in containerd 1.5.4 and 1.4.8. As a workaround, ensure that users only pull images from     trusted sources. Linux security modules (LSMs) like SELinux and AppArmor can limit the files potentially     affected by this bug through policies and profiles that prevent containerd from interacting with specific     files. (CVE-2021-32760)

  - containerd is an open source container runtime with an emphasis on simplicity, robustness and portability.
    A bug was found in containerd where container root directories and some plugins had insufficiently     restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and     execute programs. When containers included executable programs with extended permission bits (such as     setuid), unprivileged Linux users could discover and execute those programs. When the UID of an     unprivileged Linux user on the host collided with the file owner or group inside a container, the     unprivileged Linux user on the host could discover, read, and modify those files. This vulnerability has     been fixed in containerd 1.4.11 and containerd 1.5.7. Users should update to these version when they are     released and may restart containers or update directory permissions to mitigate the vulnerability. Users     unable to update should limit access to the host to trusted users. Update directory permission on     container bundles directories. (CVE-2021-41103)

  - 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)`.

The version of containerd installed on the remote host is prior to 1.4.13-2. The version of docker installed on the remote host is prior to 20.10.13-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2DOCKER-2022-018 advisory.

    A flaw was found in Moby (Docker Engine), where containers were started incorrectly with non-empty     inheritable Linux process capabilities. This flaw allows an attacker with access to programs with     inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.
    Containers using Linux users and groups to perform privilege separation inside the container are most     directly impacted. (CVE-2022-24769)

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1689-1 advisory.

  - The x/crypto/ssh package before 0.0.0-20211202192323-5770296d904e of golang.org/x/crypto allows an     attacker to panic an SSH server. (CVE-2021-43565)

  - containerd is a container runtime available as a daemon for Linux and Windows. A bug was found in     containerd prior to versions 1.6.1, 1.5.10, and 1.14.12 where containers launched through containerd's CRI     implementation on Linux with a specially-crafted image configuration could gain access to read-only copies     of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container     setup (including a Kubernetes Pod Security Policy) and expose potentially sensitive information.
    Kubernetes and crictl can both be configured to use containerd's CRI implementation. This bug has been     fixed in containerd 1.6.1, 1.5.10, and 1.4.12. Users should update to these versions to resolve the issue.

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. (CVE-2022-24769)

  - The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to     crash a server in certain circumstances involving AddHostKey. (CVE-2022-27191)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of containerd installed on the remote host is prior to 1.4.13-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2ECS-2023-023 advisory.

    A flaw was found in Moby (Docker Engine), where containers were started incorrectly with non-empty     inheritable Linux process capabilities. This flaw allows an attacker with access to programs with     inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.
    Containers using Linux users and groups to perform privilege separation inside the container are most     directly impacted. (CVE-2022-24769)

The remote host is affected by the vulnerability described in GLSA-202401-31 (containerd: Multiple Vulnerabilities)

  - containerd is a container runtime. A bug was found in containerd versions prior to 1.4.8 and 1.5.4 where     pulling and extracting a specially-crafted container image can result in Unix file permission changes for     existing files in the host's filesystem. Changes to file permissions can deny access to the expected owner     of the file, widen access to others, or set extended bits like setuid, setgid, and sticky. This bug does     not directly allow files to be read, modified, or executed without an additional cooperating process. This     bug has been fixed in containerd 1.5.4 and 1.4.8. As a workaround, ensure that users only pull images from     trusted sources. Linux security modules (LSMs) like SELinux and AppArmor can limit the files potentially     affected by this bug through policies and profiles that prevent containerd from interacting with specific     files. (CVE-2021-32760)

  - containerd is an open source container runtime with an emphasis on simplicity, robustness and portability.
    A bug was found in containerd where container root directories and some plugins had insufficiently     restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and     execute programs. When containers included executable programs with extended permission bits (such as     setuid), unprivileged Linux users could discover and execute those programs. When the UID of an     unprivileged Linux user on the host collided with the file owner or group inside a container, the     unprivileged Linux user on the host could discover, read, and modify those files. This vulnerability has     been fixed in containerd 1.4.11 and containerd 1.5.7. Users should update to these version when they are     released and may restart containers or update directory permissions to mitigate the vulnerability. Users     unable to update should limit access to the host to trusted users. Update directory permission on     container bundles directories. (CVE-2021-41103)

  - containerd is an open source container runtime. A bug was found in containerd's CRI implementation where a     user can exhaust memory on the host. In the CRI stream server, a goroutine is launched to handle terminal     resize events if a TTY is requested. If the user's process fails to launch due to, for example, a faulty     command, the goroutine will be stuck waiting to send without a receiver, resulting in a memory leak.
    Kubernetes and crictl can both be configured to use containerd's CRI implementation and the stream server     is used for handling container IO. This bug has been fixed in containerd 1.6.12 and 1.5.16. Users should     update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted     images and commands are used and that only trusted users have permissions to execute commands in running     containers. (CVE-2022-23471)

  - containerd is a container runtime available as a daemon for Linux and Windows. A bug was found in     containerd prior to versions 1.6.1, 1.5.10, and 1.14.12 where containers launched through containerd's CRI     implementation on Linux with a specially-crafted image configuration could gain access to read-only copies     of arbitrary files and directories on the host. This may bypass any policy-based enforcement on container     setup (including a Kubernetes Pod Security Policy) and expose potentially sensitive information.
    Kubernetes and crictl can both be configured to use containerd's CRI implementation. This bug has been     fixed in containerd 1.6.1, 1.5.10, and 1.4.12. Users should update to these versions to resolve the issue.
    (CVE-2022-23648)

  - 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. (CVE-2022-24769)

  - containerd is an open source container runtime. A bug was found in the containerd's CRI implementation     where programs inside a container can cause the containerd daemon to consume memory without bound during     invocation of the `ExecSync` API. This can cause containerd to consume all available memory on the     computer, denying service to other legitimate workloads. Kubernetes and crictl can both be configured to     use containerd's CRI implementation; `ExecSync` may be used when running probes or when executing     processes via an exec facility. This bug has been fixed in containerd 1.6.6 and 1.5.13. Users should     update to these versions to resolve the issue. Users unable to upgrade should ensure that only trusted     images and commands are used. (CVE-2022-31030)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
