Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Magick.NET-Q16 packages (including the AnyCPU, HDRI, OpenMP and architecture-specific variants) before 14.10.3 are affected. ImageMagick's path policy checks the raw filename before path traversal is resolved, so an attacker who can supply a crafted filename to a program using ImageMagick can read files that the policy is meant to block, even when a secure policy is in place. Upgrade to version 14.10.3. The source gives few details on the workaround beyond adding policy rules to block writes, which was not described in full.
