XRegion in TigerVNC allows remote VNC servers to cause a denial of service (NULL pointer dereference) by leveraging failure to check a malloc return value, a similar issue to CVE-2014-6052.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
