How to fix?

Upgrade Chainguard uutils to version 0.9.0-r0 or higher.

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.

A logic error in the ln utility of uutils coreutils causes the program to reject source paths containing non-UTF-8 filename bytes when using target-directory forms (e.g., ln SOURCE... DIRECTORY). While GNU ln treats filenames as raw bytes and creates the links correctly, the uutils implementation enforces UTF-8 encoding, resulting in a failure to stat the file and a non-zero exit code. In environments where automated scripts or system tasks process valid but non-UTF-8 filenames common on Unix filesystems, this divergence causes the utility to fail, leading to a local denial of service for those specific operations.
