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."

En otros sistemas tipo Unix como macOS y FreeBSD, la utilidad no logra utilizar estas protecciones, dejando las operaciones de salto de directorio vulnerables a condiciones de carrera de enlaces simbólicos."
