A privilege escalation flaw was found in the Xorg-x11-server due to a lack of authentication for X11 clients. This flaw allows an attacker to take control of an X application by impersonating the server it is expecting to connect to.
The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.
