Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Magick.NET-Q16 NuGet packages (AnyCPU, HDRI, OpenMP and architecture-specific variants for x64, x86 and arm64) are affected before version 14.8.0, which contains the fix. A heap-buffer over-read in MNG image magnification with separate alpha channels can be triggered by processing a crafted MNG file, potentially leaking memory contents into the output image. Upgrade to version 14.8.0 or later.
