Description: Numerous vulnerabilities in the X11 server allow execution of arbitrary code with the privileges of the user running the X11 server if the attacker can authenticate to the X11 server. This is a security vulnerability only if the X11 server is configured to not require authentication, which Apple does not recommend. This update fixes the issue by applying the updated X.Org patches. Further information is available via the X.Org website at http://www.x.org/wiki/Development/Security
