## Overview

ImageMagick before 7.1.2-22 contains an information disclosure vulnerability in the PasskeyEncipherImage method due to AES-CTR nonce reuse. Attackers can exploit nonce reuse in the cipher implementation to recover plaintext information from encrypted images.

## 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.
