## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-2gq3-ww97-wfjm. This link is maintained to preserve external references.

### Original Description
ImageMagick before 7.1.2-15 and 6.9.13-40 contains a heap use-after-free in the meta coder: when memory allocation fails, a single byte is written to a stale pointer. Remote attackers can trigger it by processing specially crafted image files, causing a denial of service.

## Affected packages

- `Magick.NET-Q16-AnyCPU < 14.10.3`

## Remediation

Upgrade to a patched release:

- `Magick.NET-Q16-AnyCPU 14.10.3`
