CBL Mariner 2.0 Security Update: containerd / containerd2 / moby-containerd / moby-containerd-cc (CVE-2024-40635)

medium Nessus Plugin ID 235228

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of containerd / containerd2 / moby-containerd / moby-containerd-cc installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-40635 advisory.

 - containerd is an open-source container runtime. A bug was found in containerd prior to versions 1.6.38, 1.7.27, and 2.0.4 where containers launched with a User set as a `UID:GID` larger than the maximum 32-bit signed integer can cause an overflow condition where the container ultimately runs as root (UID 0). This could cause unexpected behavior for environments that require containers to run as a non-root user. This bug has been fixed in containerd 1.6.38, 1.7.27, and 2.04. As a workaround, ensure that only trusted images are used and that only trusted users have permissions to import images. (CVE-2024-40635)

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 packages.
