Duplicate Advisory: uutils coreutils has an Improper Handling of Unicode Encoding Issue

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-jcjr-rh8q-7xqf. This link is maintained to preserve external references.

Original Description

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.
