Description Jon Weiser 2026-06-29 15:03:41 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.

Comment 1 Paul Holzinger 2026-06-29 16:59:22 UTC
Rawhide ships podman 6 already which contains the fix for the problem. And f43 and f43 ships podman 5.8 which also have the fix for this
