Description

A time-of-check to time-of-use (TOCTOU) race condition vulnerability was found in acl. By replacing a pathname component with a symbolic link between a security check and subsequent file operations, an attacker can redirect file access control list operations. This occurs when privileged processes invoke `getfacl` or `setfacl` over an attacker-controlled path, potentially leading to local privilege escalation.
