Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Magick.NET-Q16 builds (all variants) before 14.12.0 have an out-of-bounds access in ConnectedComponentsImage() when the connected-components define is given an invalid index, which causes an access violation. An attacker who controls these command-line artifacts can trigger it. Upgrade to 14.12.0 or later.
