Magick.NET-Q16 packages (AnyCPU, HDRI, OpenMP and architecture-specific variants for arm64, x64 and x86) before 14.10.4 are vulnerable to a heap overflow when writing an extremely large image profile during PNG encoding. The source gives few details about the attack conditions or the impact beyond the overflow itself. Upgrade the affected packages to version 14.10.4.
