Synopsis
The remote SUSE host is missing one or more security updates.
Description
The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0213-1 advisory.
- Moby is an open-source project created by Docker to enable software containerization. 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. 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. (CVE-2021-41091)
- 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. (CVE-2021-41092)
- 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)
- 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)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the affected containerd and / or docker packages.

How to Run
Here is how to run the SUSE SLES12 Security Update : containerd, docker (SUSE-SU-2022:0213-1) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):
- Click to start a New Scan.
- Select Advanced Scan.
- Navigate to the Plugins tab.
- On the top right corner click to Disable All plugins.
- On the left side table select SuSE Local Security Checks plugin family.
- On the right side table select SUSE SLES12 Security Update : containerd, docker (SUSE-SU-2022:0213-1) plugin ID 157188.
- Specify the target on the Settings tab and click to Save the scan.
- Run the scan.
Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.
Basic usage:
/opt/nessus/bin/nasl suse_SU-2022-0213-1.nasl -t <IP/HOST>
Run the plugin with audit trail message on the console:
/opt/nessus/bin/nasl -a suse_SU-2022-0213-1.nasl -t <IP/HOST>
Run the plugin with trace script execution written to the console (useful for debugging):
/opt/nessus/bin/nasl -T - suse_SU-2022-0213-1.nasl -t <IP/HOST>
Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):
/opt/nessus/bin/nasl -K /tmp/state suse_SU-2022-0213-1.nasl -t <IP/HOST>
Go back to menu.
