X.Org libXxf86vm 'XF86VidModeGetGammaRamp()' Function Remote Code Execution Vulnerability

The 'llibXxf86vm' library is prone to a remote code-execution vulnerability because it fails to adequately bounds-check user-supplied data.

An attacker can exploit this vulnerability to execute arbitrary code with elevated privileges. Failed exploit attempts will likely cause denial-of-service conditions.

Versions prior to libXxf86vm 1.1.3 are vulnerable.
