Description: Some security issues have been reported in X.Org X11, which can be exploited by malicious, local users to perform certain actions with escalated privileges. The security issues are caused due to missing checks whether the setuid() or similar calls have succeeded. This can be exploited to perform certain actions with root privileges if the calls fail due to e.g. resource limits. The security issues has been reported in versions 6.7.0 through 7.1.0. Other versions may also be affected. Solution: Apply patches.
