Kerentanan Time-of-check Time-of-use (TOCTOU) Race Condition pada uutils coreutils. Skor CVSS 3.1 7.0 (High) menurut ubuntu.com.

Deskripsi (NVD)

A Time-of-Check to Time-of-Use (TOCTOU) race condition exists in the mkfifo utility of uutils coreutils. The utility creates a FIFO and then performs a path-based chmod to set permissions. A local attacker with write access to the parent directory can swap the newly created FIFO for a symbolic link between these two operations. This redirects the chmod call to an arbitrary file, potentially enabling privilege escalation if the utility is run with elevated privileges.
