Kerentanan Time-of-check Time-of-use (TOCTOU) Race Condition pada uutils coreutils. Skor CVSS 3.1 4.7 (Medium) menurut ubuntu.com.

Deskripsi (NVD)

A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the mv utility of uutils coreutils during cross-device moves. The extended attribute (xattr) preservation logic uses multiple path-based system calls that perform fresh path-to-inode lookups for each operation. A local attacker with write access to the directory can exploit this race to swap files between calls, causing the destination file to receive an inconsistent mix of security xattrs, such as SELinux labels or file capabilities.
