CVE-2026-109267 · Severity: medium · CVSS 5.3 · Published 2026-10-12

ImageMagick is an image processing library used across many applications to convert and manipulate images. A vulnerability in its MSL (Magick Scripting Language) image decoder allows attackers to provide specially crafted images that consume all available memory on the stack, causing the application to crash. This denial-of-service condition can disrupt services that rely on ImageMagick to process user-supplied images.

## How to fix

- Fixed in 6.9.13-57, 7.1.2-32

## Technical details

The MSL decoder contains an uncontrolled recursion vulnerability caused by an incorrect depth check that fails to limit how deeply the decoder can recurse when processing nested MSL structures. An attacker supplying a crafted MSL image can trigger unbounded recursion that exhausts the stack, crashing the process. The fix corrects the depth-checking logic to properly prevent excessive recursion.

## Affected products

- ImageMagick ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32
