Doc Text:
A flaw was found in ImageMagick. This vulnerability allows an attacker to cause a Denial of Service (DoS) by supplying a specially crafted DJVU image file. When ImageMagick processes the image under conditions where memory allocation fails, the DJVU decoder fails to validate the allocation result, causing the application to crash.

Description OSIDB Bzimport 2026-10-25 13:35:35 UTC
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a null pointer dereference in the DJVU decoder because the result of a memory allocation is not checked before use. Attackers can supply a DJVU image that, when processed under conditions where the allocation fails, crashes the process and causes a denial of service.
