## Overview

ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the JNG encoder that fails to release allocated memory when processing a crafted image. Attackers can supply crafted images that are encoded to JNG to leak memory, potentially causing resource exhaustion and a limited denial of service.

## Affected

- `ImageMagick >= 7.0.0-0 < 7.1.2-33`
- `ImageMagick < 6.9.13-58`

## Remediation
