Machine-written summary

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

The Magick.NET-Q16 NuGet packages before 14.11.1 contain an out-of-bounds write of a zero byte in ImageMagick's X11 display interaction path, which could lead to a crash. The source gives few details about what an attacker would need to trigger it. Upgrade to version 14.11.1 or later.
