# Duplicate Advisory: ImageMagick: Malicious PCD files trigger 1‑byte heap Out-of-bounds Read and DoS

Link for people: https://infrastack.ai/live/GHSA-jmqv-2mx7-544h (this .md is for agents)

This advisory is withdrawn as a duplicate of GHSA-wgxp-q8xq-wpp9. The original text says a crafted PCD image file can trigger a one-byte heap out-of-bounds read during decoding, causing denial of service and possibly leaking an adjacent heap byte.

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

## Affected

- nuget:Magick.NET-Q16-AnyCPU affected < 14.10.3 fixed 14.10.3

## How to check

- Check whether the project references the `Magick.NET-Q16-AnyCPU` NuGet package and its version, for example in the `.csproj` file or `packages.lock.json`.
- Check whether the app decodes untrusted PCD files.

## Fix

- `Magick.NET-Q16-AnyCPU` versions before `14.10.3` are affected; the source lists `14.10.3` as fixed.
- Use GHSA-wgxp-q8xq-wpp9 for the current advisory.

## From the sources

### Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-wgxp-q8xq-wpp9. This link is maintained to preserve external references.

### Original Description
ImageMagick before 7.1.2-15 (and 6.x before 6.9.13-40) contains a heap out-of-bounds read in the PCD coder's DecodeImage loop. A crafted PCD file can trigger a one-byte heap out-of-bounds read during image decoding, resulting in denial of service and potential disclosure of an adjacent heap byte.
