Machine-written summary

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

Magick.NET-Q16 packages (AnyCPU, HDRI, OpenMP and architecture-specific variants) before 14.10.3 contain a heap buffer over-read in the MAP image decoder. An attacker who can supply a crafted MAP file for the application to decode could cause a crash or disclose unintended memory contents. The fix is to upgrade to version 14.10.3.
