Description
CNA (VulnCheck)
ImageMagick before 7.1.2-33 contains a heap buffer overflow vulnerability on 32-bit systems that allows attackers to overwrite heap memory when convex-hull information is requested. Attackers can supply crafted images processed with convex-hull calculations to corrupt heap memory, causing crashes or potential code execution.
