enlightenment_sys in Enlightenment before 0.25.4 allows local users to gain privileges because it is setuid root, and the system library function mishandles pathnames that begin with a /dev/.. substring.
Weakness
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
