## Overview

ImageMagick before 7.1.2-22 contains a division by zero vulnerability in binomial kernel processing that allows attackers to cause denial of service. An attacker can supply a large binomial kernel value causing integer overflow, resulting in division by zero and application crash.

## Affected

- `ImageMagick >= 7.0.0 < 7.1.2-22`
- `ImageMagick < 6.9.13-47`

## Remediation

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