Xorg-x11-server: tigervnc: heap-based buffer overflow privilege escalation vulnerability

A flaw was found in the X.org server. Due to improperly tracked allocation size in _XkbSetCompatMap, a local attacker may be able to trigger a buffer overflow condition via a specially crafted payload, leading to denial of service or local privilege escalation in distributions where the X.org server is run with root privileges.
