Duplicate Advisory: uutils coreutils has a Time-of-Check to Time-of-Use (TOCTOU) race condition

Published Apr 22, 2026·Updated Jul 6, 2026

NVD Description

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-239g-2685-54x3. This link is maintained to preserve external references. ### Original Description The install utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition during file installation. The implementation unlinks an existing destination file and then recreates it using a path-based operation without the O_EXCL flag. A local attacker can exploit the window between the unlink and the subsequent creation to swap the path with a symbolic link, allowing them to redirect privileged writes to overwrite arbitrary system files.
