MEDIUM 6.5WATCHLISTDOWNGRADEDOWNGRADEDOWNGRADE

CVE-2024-9676 is a medium-severity flaw (CVSS 6.5) affecting openshift container platform, openshift container platform for arm64, openshift container platform for ibm z. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A vulnerability was found in Podman, Buildah, and CRI-O. A symlink traversal vulnerability in the containers/storage library can cause Podman, Buildah, and CRI-O to hang and result in a denial of service via OOM kill when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). The containers/storage library will read /etc/passwd inside the container, but does not properly validate if that
