Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, 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. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.
