Summary
ImageMagick before 7.1.2-33 contains a heap buffer overflow on 32-bit systems when convex-hull information is requested. An attacker who supplies a crafted image can overwrite heap memory, which causes crashes or possibly code execution. The flaw is an integer overflow (CWE-190). A local attacker needs a user to process the crafted image.
