{"id":"GHSA-w6xc-g9qj-vp32","summary":"uucore: safe_traversal TOCTOU protection only enabled on Linux","details":"The safe_traversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use (TOCTOU) symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize these protections, leaving directory traversal operations vulnerable to symlink race conditions.\n\n---\n_Zellic finding 3.59.
