Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Magick.NET-Q16-AnyCPU, Magick.NET-Q16-arm64, Magick.NET-Q16-HDRI-AnyCPU.
  2. 2Review the reported fix. Update Magick.NET-Q16-AnyCPU to 14.10.3; Magick.NET-Q16-arm64 to 14.10.3; Magick.NET-Q16-HDRI-AnyCPU to 14.10.3; Magick.NET-Q16-HDRI-arm64 to 14.10.3; Magick.NET-Q16-HDRI-OpenMP-arm64 to 14.10.3; Magick.NET-Q16-HDRI-OpenMP-x64 to 14.10.3; Magick.NET-Q16-HDRI-x64 to 14.10.3; Magick.NET-Q16-HDRI-x86 to 14.10.3; Magick.NET-Q16-OpenMP-arm64 to 14.10.3; Magick.NET-Q16-OpenMP-x64 to 14.10.3; Magick.NET-Q16-OpenMP-x86 to 14.10.3; Magick.NET-Q16-x64 to 14.10.3; Magick.NET-Q16-x86 to 14.10.3; Magick.NET-Q8-AnyCPU to 14.10.3; Magick.NET-Q8-arm64 to 14.10.3; Magick.NET-Q8-OpenMP-arm64 to 14.10.3; Magick.NET-Q8-OpenMP-x64 to 14.10.3; Magick.NET-Q8-x64 to 14.10.3; Magick.NET-Q8-x86 to 14.10.3 if you use the affected versions.
