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 sort utility in uutils coreutils is vulnerable to a process panic when using the --files0-from option with inputs containing non-UTF-8 filenames. The implementation enforces UTF-8 encoding and utilizes expect(), causing an immediate crash when encountering valid but non-UTF-8 paths. This diverges from GNU sort, which treats filenames as raw bytes. A local attacker can exploit this to crash the utility and disrupt automated pipelines.
