NVD Description

Note: Versions mentioned in the description apply only to the upstream k3s-fips-1.34 package and not the k3s-fips-1.34 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

containerd is an open-source container runtime. Prior to 1.7.35, 2.0.12, 2.2.8, and 2.3.5, containerd's layer unpack handler repeatedly traverses directories for certain opaque whiteout configurations. A malicious image layer can trigger repeated directory traversals while opaque whiteouts are processed. Pulling or importing the image can consume CPU, delay container startup, and reduce image-pull concurrency for unrelated deployments. This issue is fixed in versions 1.7.35, 2.0.12, 2.2.8, and 2.3.5.
