Official Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride (row size) for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
