Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for Magick.NET-Q16-AnyCPU

How to Check if You Are Affected

To determine whether your application is affected by GHSA-rvhp-75f6-9jqh, inspect your project dependencies for ImageMagick:

inspect dependencies for Magick.NET-Q16-AnyCPU

Analyze the terminal output to locate any version of ImageMagick in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.15.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In ImageMagick, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Matrix bases operations like `-canny` are missing a check for allowed memory allocation that could result allocating more memory than allowed.
