Docker CLI is the command line interface for the docker container runtime. A bug was found in the Docker CLI where running `docker login my-private-registry.example.com` with a misconfigured configuration file (typically `~/.docker/config.json`) listing a `credsStore` or `credHelpers` that could not be executed would result in any provided credentials being sent to `registry-1.docker.io` rather than the intended private registry. This bug has been fixed in Docker CLI 20.10.9. Users should update to this version as soon as possible. For users unable to update ensure that any configured credsStore or credHelpers entries in the configuration file reference an installed credential helper that is executable and on the PATH.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The version of docker installed on the remote host is prior to 20.10.7-3. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2ECS-2023-028 advisory.

    A file permissions vulnerability was found in Moby (Docker Engine). Copying files by using  into a     specially-crafted container can result in Unix file permission changes for existing files in the host's     filesystem, which might lead to permissions escalation and allow an attacker access to restricted data.
    (CVE-2021-41089)

    Moby is an open-source project created by Docker to enable software containerization. A bug was found in     Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with     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 bug has been fixed     in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible. Running     containers should be stopped and restarted for the permissions to be fixed. For users unable to upgrade     limit access to the host to trusted users. Limit access to host volumes to trusted containers.

  - The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution     of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone     was used to determine the type of document during push and pull operations. Documents that contain both     manifests and layers fields could be interpreted as either a manifest or an index in the absence of an     accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a     client may interpret the resulting content differently. The OCI Distribution Specification has been     updated to require that a mediaType value present in a manifest or index match the Content-Type header     used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type     header and reject an ambiguous document that contains both manifests and layers fields or manifests     and config fields if they are unable to update to version 1.0.1 of the spec. (CVE-2021-41190)

  - runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. A bug     was found in runc prior to version 1.1.2 where `runc exec --cap` created processes 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). 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 runc 1.1.2. This fix     changes `runc exec --cap` behavior such that the additional capabilities granted to the process being     executed (as specified via `--cap` arguments) do not include inheritable capabilities. In addition, `runc     spec` is changed to not set any inheritable capabilities in the created example OCI spec (`config.json`)     file. (CVE-2022-29162)

  - The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution     of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone     was used to determine the type of document during push and pull operations. Documents that contain both     manifests and layers fields could be interpreted as either a manifest or an index in the absence of an     accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a     client may interpret the resulting content differently. The OCI Distribution Specification has been     updated to require that a mediaType value present in a manifest or index match the Content-Type header     used during the push and pull operations. Clients pulling from a registry may distrust the Content-Type     header and reject an ambiguous document that contains both manifests and layers fields or manifests     and config fields if they are unable to update to version 1.0.1 of the spec.

A bug was found in     Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container     can result in Unix file permission changes for existing files in the host's filesystem, widening access to     others. This bug does not directly allow files to be read, modified, or executed without an additional     cooperating process. This bug has been fixed in Moby (Docker Engine) 20.10.9. Users should update to this     version as soon as possible. Running containers do not need to be restarted. (CVE-2021-41089)

  - Moby is an open-source project created by Docker to enable software containerization. A bug was found in     Moby (Docker Engine) where the data directory (typically `/var/lib/docker`) contained subdirectories with     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 bug has been fixed     in Moby (Docker Engine) 20.10.9. Users should update to this version as soon as possible.

  - runc before 1.0.0-rc95 allows a Container Filesystem Breakout via Directory Traversal.

  - 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.
