Doc Text:
A flaw was found in ImageMagick. When generating minimum-bounding-box output for an image, the application can read past allocated memory boundaries, resulting in a heap buffer over-read. An attacker could exploit this flaw by supplying a specially crafted image file to be processed. Successful exploitation could lead to information disclosure by exposing adjacent heap memory data, or cause the application to crash, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-10-25 13:33:36 UTC 
ImageMagick before 7.1.2-33 contains a heap buffer over-read vulnerability that allows attackers to read beyond allocated memory when printing a minimum-bounding-box. Attackers can supply a crafted image that triggers the over-read during minimum-bounding-box output, causing crashes or exposing adjacent heap memory.
