A flaw was found in ImageMagick. A stack-based buffer overflow vulnerability exists in the handling of bzip2 compressed images, where stack memory can be overwritten during decoding. By submitting a specially crafted image, an attacker can exploit this issue to cause memory corruption or crash the application, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-10-25 13:34:02 UTC
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.
