CVE-2024-9676 Information

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.
