Description

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a policy bypass in the PCD (and, per the upstream advisory, CUBE and HALD) coder: when a specific command line option is supplied, the decoder does not check a configured resource limit, which can result in extra memory allocation. A local user able to pass command line options to ImageMagick can therefore exceed the intended memory policy limit, causing a limited availability impact. The issue is fixed in 7.1.2-31 and 6.9.13-56.

Affected products

• ImageMagick: before 6.9.13-56; from 7.0.0-0 before 7.1.2-31 — fixed in 6.9.13-56, 7.1.2-31
• ImageMagick: from 7.0.0 before 7.1.2-31 — fixed in 7.1.2-31

How to fix

Upgrade to a fixed version: ImageMagick 6.9.13-56, 7.1.2-31; ImageMagick 7.1.2-31. Check the vendor advisory for mitigations.
