Status: published. Published: 2026-10-25. Updated: 2026-11-03.

ImageMagick before 7.1.2-33 contains a memory leak vulnerability in the magick compare command caused by missing cleanup when an operation fails. Attackers can supply inputs that trigger repeated failed compare operations to exhaust memory and cause denial of service.

## Remediation

No remediation reported in collected sources

## Affected products and versions

- imagemagick / imagemagick: < 7.1.2-33 (affected, custom). Source: NVD
