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 architecture-specific variants) before 14.10.3 are vulnerable to a division-by-zero in YUV sampling factor validation. An attacker who can get the application to load a crafted image can crash it, causing a denial of service. Upgrade to version 14.10.3 or later.
