Kerentanan Time-of-check Time-of-use (TOCTOU) Race Condition pada uutils coreutils. Skor CVSS 3.1 6.3 (Medium) menurut ubuntu.com.

Deskripsi (NVD)

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.
