Description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-30 and 6.9.13-55, a crafted highly compressed MAT image can make the MAT decoder create temporary files larger than the configured security-policy limit, bypassing resource restrictions and consuming excessive disk space. This issue is fixed in versions 7.1.2-30 and 6.9.13-55.

Affected products

• ImageMagick: before 6.9.13-55; from 7.0.0-0 before 7.1.2-30 — fixed in 6.9.13-55, 7.1.2-30

How to fix

Upgrade to a fixed version: ImageMagick 6.9.13-55, 7.1.2-30. Check the vendor advisory for mitigations.
