Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Multiple Magick.NET-Q16 packages (including AnyCPU, HDRI, and OpenMP builds) before 14.10.3 have a memory leak in several coders that write raw pixel data, where an object is not freed. The source gives few details on what an attacker needs to trigger it or what the leak allows. Upgrade to version 14.10.3.
