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, including the AnyCPU, HDRI, OpenMP, and arm64, x64, and x86 variants, contain a heap buffer over-read in BilateralBlurImage. An attacker who can get a crafted image processed with the bilateral blur operation can trigger an out-of-bounds read. Upgrade to version 14.10.4 or later.
