The aufs module for the Linux kernel 3.x and 4.x does not properly maintain POSIX ACL xattr data, which allows local users to gain privileges by leveraging a group-writable setgid directory.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
