The remote host is affected by the vulnerability described in GLSA-200608-25 (X.org and some X.org libraries: Local privilege escalations)
Several X.org libraries and X.org itself contain system calls to set*uid() functions, without checking their result.
Impact :
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.
Workaround :
There is no known workaround at this time.
