Title
ImageMagick - Heap Buffer Overflow via Off-by-One in Morphology Processing
Summary
ImageMagick before 7.1.2-19 contains an off-by-one error in morphology validation allowing out-of-bounds heap buffer reads. Attackers can trigger heap buffer overflow by providing incorrect morphology parameters causing single pixel memory access violations.
