VUL-0: CVE-2023-25173: helm, helm3: Supplementary groups are not set up properly
Last modified: 2023-11-01 09:13:01 UTC
+++ This bug was initially created as a clone of Bug #1208426 +++ 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.

if I understand this correctly, this has been fixed in helm 3.12.0. we have a pending security update in https://build.suse.de/package/show/SUSE:Maintenance:30887/helm.SUSE_SLE-15_Update that updates to 3.13.0 which should include the fix. I've adjusted the changes file to include the bug and CVE reference and submitted that again under SR 309201
