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 touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create(), which internally uses O_TRUNC. An attacker can exploit this window to create a file or swap a symlink at the target path, causing touch to truncate an existing file and leading to permanent data loss.
