# Duplicate Advisory: ImageMagick: Integer Overflow in PSB (PSD v2) RLE decoding path causes heap Out of Bounds reads for 32-bit builds

This advisory is a withdrawn duplicate of GHSA-273h-m46v-96q4, which covers the same ImageMagick PSB decoding flaw. A crafted PSB file processed on a 32-bit build can read heap memory out of bounds, leaking data or crashing the process.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- nuget:Magick.NET-Q8-x86 affected < 14.10.3 fixed 14.10.3

## How to check

- Check the installed Magick.NET-Q8-x86 package version in the project file; unknown whether it is below `14.10.3`.
- Look for ImageMagick builds that process untrusted PSD/PSB files on 32-bit systems.

## Fix

- Magick.NET-Q8-x86 move to `14.10.3` (per the product range in this advisory).
- ImageMagick: the original description names `7.1.2-15` and `6.9.13-40` as fixed versions.

## From the sources

### 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This advisory has been withdrawn because it is a duplicate of GHSA-273h-m46v-96q4.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.
