CVE-2023-25173 Open this link in a new tabHow to fix?
Upgrade github.com/containerd/containerd/oci to version 1.5.18, 1.6.18 or higher.
Overview
Affected versions of this package are vulnerable to Improper Privilege Management such that 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.
Workaround
Users should ensure that the "USER $USERNAME" Dockerfile instruction is not used. Instead, users should set the container entrypoint to a value similar to ENTRYPOINT ["su", "-", "user"] to allow su to properly set up supplementary groups.
