Description
A logic error in the ln utility of the uutils coreutils Rust implementation causes it to reject source paths with non-UTF-8 filename bytes when using target-directory forms. Unlike GNU ln, which treats filenames as raw bytes, uutils coreutils enforces UTF-8 encoding, leading to failure to stat such files and a non-zero exit code. This results in local denial of service for automated scripts or system tasks handling valid non-UTF-8 filenames on Unix filesystems. The issue affects multiple versions prior to 0.10.0-1ubuntu1 and has a medium severity rating.
