If you cannot patch yet, users should be cautious when using Root.Chmod in environments where untrusted users can replace files with symlinks during operations. Consider implementing additional application-level checks or avoiding use of vulnerable versions if possible.
Description
On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation.
