Executive brief
ImageMagick is a software suite used to create, edit, and convert images. A vulnerability in its option parsing component allows a small amount of memory to be leaked when the software processes invalid commands. While the impact of a single occurrence is minor, repeated exploitation could eventually lead to system performance issues or service instability.
Technical details
A memory leak vulnerability (CWE-401) exists in ImageMagick's wand option parser. The issue is triggered when the parser receives invalid arguments, failing to properly release allocated memory during the error handling or cleanup phase. An attacker with local access can exploit this by repeatedly providing malformed options to exhaust available system memory over time. The vulnerability is addressed in Magick.NET version 14.14.0.
