If you cannot patch yet, users on non-Linux Unix-like systems should be aware of the potential risk when using uutils coreutils for directory traversal operations. No vendor advisory or patch links are currently provided.
Description
A TOCTOU (Time-of-Check to Time-of-Use) race condition exists in the safe_traversal module of uutils coreutils. This module uses file-descriptor-relative syscalls to protect against symlink race conditions but only on Linux systems. On other Unix-like systems such as macOS and FreeBSD, these protections are not applied, leaving directory traversal vulnerable to symlink race attacks. The vulnerability has a low severity score and currently no known exploits or patches.
