NVD Description

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

The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This flaw breaks backups and migrations, causing files moved by a privileged user (e.g., root) to become root-owned unexpectedly, which can lead to information disclosure or restricted access for the intended owners.
