Machine-written summary

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

Magick.NET-Q16 packages before 14.10.4 contain a heap use-after-free in the MSL encoder, where a cloned image is destroyed twice. The source gives few details on what an attacker needs to trigger it. Upgrade to 14.10.4, which removes the MSL write capability.
