Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Magick.NET-Q16 packages (AnyCPU, HDRI, OpenMP, and per-architecture builds) before 14.10.3 contain a NULL pointer dereference in ClonePixelCacheRepository. A remote attacker who supplies a crafted image file can crash any application that processes it, causing a denial of service. Upgrade the affected packages to version 14.10.3.
