[GLSA-200608-25] X.org and some X.org libraries: Local privilege escalations |

X.org and some X.org libraries: Local privilege escalations Detailed Explanation for this Vulnerability Assessment 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 rights 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.
