Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Magick.NET packages (Q16, HDRI and OpenMP variants for AnyCPU, x64, x86 and arm64) before 14.10.3 are vulnerable to a heap buffer overflow write in the YUV 4:2:2 decoder when processing a malicious YUV image. The source gives few details on how the image is supplied or what an attacker can achieve beyond the memory write. Upgrade to version 14.10.3 or later.
