Vulnerability Assessment Details

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