Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
ImageMagick's Magick.NET packages (NuGet Magick.NET-Q16 variants, including the AnyCPU, HDRI, OpenMP, x64, x86 and arm64 builds) before version 14.13.1 are affected. A missing check in the PSD decoder lets a crafted PSD image bypass the list-length resource policy during decoding, while other security limits still apply. Upgrade to version 14.13.1 or later.
