Machine-written summary

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

Magick.NET packages (Q8-x64, Q16 AnyCPU, Q16-HDRI, and OpenMP variants for x64, x86, and arm64) before 14.10.3 are vulnerable. A user opening a crafted PSB (PSD v2) file in a 32-bit build can trigger an integer overflow that causes a heap out-of-bounds read, leading to information disclosure or a crash. Upgrade to version 14.10.3 or later.
