NVD Description

Note: Versions mentioned in the description apply only to the upstream podmansh package and not the podmansh package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

Podman is a tool for managing OCI containers and pods. From 3.0.0 until 5.7.1, running a malicious container image where the WORKDIR path contains a symlink can create a directory or modify ownership on the host filesystem. Modified ownership is less likely to happen as that requires help from an untrusted/malicious process that mutates the host filesystem tree during dereferencing of the WORKDIR path, to trigger a race condition. This vulnerability is fixed in 5.7.1.
