## Overview

ImageMagick before 7.1.2-31 contains a policy bypass vulnerability in the UHDR encoder that fails to perform policy checks during buffer allocation for image pixels. Attackers can bypass resource policies by processing specially crafted UHDR images, potentially causing denial of service through excessive memory allocation.

## Affected

- `imagemagick < 7.1.2-31`

## Remediation

Upgrade past the affected range:

- `imagemagick 7.1.2-31`
