The WPG format reader in GraphicsMagick 1.3.25 and earlier allows remote attackers to cause a denial of service (assertion failure and crash) via vectors related to a ReferenceBlob and a NULL pointer.

Weakness

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.
