Summary
ImageMagick vulnerable to stack corruption through long morphology kernel names or arrays
Details
A stack buffer overflow exists in ImageMagick's morphology kernel parsing functions. User-controlled kernel strings exceeding a buffer are copied into fixed-size stack buffers via memcpy without bounds checking, resulting in stack corruption.
Severity
7.1 (High)
