Doc Text:
A flaw was found in ImageMagick. The handling of the color decision list (-cdl) option fails to properly release allocated memory after use. An attacker can exploit this issue by providing input that repeatedly processes the -cdl option, leading to excessive memory consumption and a Denial of Service (DoS) through resource exhaustion.

Description OSIDB Bzimport 2026-10-25 13:32:09 UTC
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the handling of the -cdl (color decision list) option, where allocated memory is not cleaned up after use. Attackers can supply input that causes the -cdl option to be processed, repeatedly leaking memory and degrading availability through resource exhaustion.
