X.org is an implementation of the X Window System.
Several X.org libraries and X.org itself contain system calls to set*uid() functions, without checking their result.
Local users could deliberately exceed their assigned resource limits and elevate their privileges after an unsuccessful set*uid() system call. This requires resource limits to be enabled on the machine.
There is no known workaround at this time.
