What is CVE-2026-116159?

A memory leak vulnerability exists in ImageMagick versions prior to 6.9.13-58 and 7.x before 7.1.2-33 due to improper handling of the '-cdl' (color decision list) option. When exploited, this flaw allows attackers to supply crafted input that leads to the repeated processing of the '-cdl' option. This results in allocated memory not being released, ultimately causing resource exhaustion and degrading the availability of the affected system.

Affected Version(s)

ImageMagick 7.0.0-0 < 7.1.2-33

ImageMagick 0 < 6.9.13-58

ImageMagick 7.1.2-33
