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)

The cp utility in uutils coreutils is vulnerable to an information disclosure race condition. Destination files are initially created with umask-derived permissions (e.g., 0644) before being restricted to their final mode (e.g., 0600) later in the process. A local attacker can race to open the file during this window; once obtained, the file descriptor remains valid and readable even after the permissions are tightened, exposing sensitive or private file contents.
