A null pointer dereference vulnerability in devices/gdevtsep.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted postscript file. This is fixed in v9.51.
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.
