Sources and claim methodology

Upstream source description

ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a stack-based buffer overflow in the handling of bzip2 compressed images. Attackers can supply a crafted image using bzip2 compression to overwrite stack memory during decoding, causing crashes or memory corruption.
