## Overview

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-273h-m46v-96q4. This link is maintained to preserve external references.

### Original Description
ImageMagick before 7.1.2-15 and 6.9.x before 6.9.13-40 contains an integer overflow in the PSB (PSD v2) RLE decoding path (ReadPSDChannelRLE in coders/psd.c) that causes a heap out-of-bounds read on 32-bit builds. Processing a crafted PSB file can lead to information disclosure or a crash.

## Affected packages

- `Magick.NET-Q8-x86 < 14.10.3`

## Remediation

Upgrade to a patched release:

- `Magick.NET-Q8-x86 14.10.3`
