Description
ImageMagick before 7.1.2-34 contains a heap-based buffer overflow in its -morph processing, where crafted images cause writes beyond the bounds of a heap buffer. An attacker can supply a crafted image that, when processed by a user with the -morph option, corrupts heap memory and crashes the application.
