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-7c7m-fpjw-gwcq, 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-401: Missing Release of Memory after Effective Lifetime, where the product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse. 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

When transforming an image to the log colorspace a small memory leak happens when the operation fails.
