SUSE SLES15 / openSUSE 15 Security Update : docker (SUSE-SU-2023:0795-1)

medium Nessus Plugin ID 172664

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:0795-1 advisory.

- 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. (CVE-2022-36109)

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 docker, docker-bash-completion, docker-fish-completion and / or docker-zsh-completion packages.
