CVE-2023-25173: Containerd supplementary groups are not set up properly inside a container

CVE-2023-25173:
Containerd is an open source container runtime. A bug was found in containerd prior to versions 1.6.18 and 1.5.18 where 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. Downstream applications that use the containerd client library may be affected as well. This bug has been fixed in containerd v1.6.18 and v.1.5.18. Users should update to these versions and recreate containers to resolve this issue. Users who rely on a downstream application that uses containerd\'s client library should check that application for a separate advisory and instructions. As a workaround, ensure that the \\\"USER $USERNAME\\\" Dockerfile instruction is not used. Instead, set the container entrypoint to a value similar to ENTRYPOINT [\\\"su\\\", \\\"-\\\", \\\"user\\\"] to allow su to properly set up supplementary groups.

It is on the roadmap to fix it?

I fail to see how this affects Ofelia or even any fork like Chadburn.

The underlying infrastructure should always be maintained. It's not like a rotisserie chicken cooker advertisement where you should just "set it and forget it".

I don't believe from the description here that this has anything to do with Ofelia. You are welcome to prove me wrong.
