## Overview

ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a null pointer dereference in the DJVU decoder because the result of a memory allocation is not checked before use. Attackers can supply a DJVU image that, when processed under conditions where the allocation fails, crashes the process and causes a denial of service.

## Affected

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

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
