CVE-2024-9676
A vulnerability was found in Podman, Buildah, and CRI-O.
Does this matter?
Lower severity and a low EPSS score (1.34%). Track it; it rarely justifies an emergency change on its own.
Description
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 file is a symlink, which can be used to cause the library to read an arbitrary file on the host.
