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 x64, x86, arm64 variants) before 14.10.3 are affected by a memory leak in the TXT coder when ImageMagick is built without FreeType. A texture attribute on a TXT file can leave an image object unreleased when metric retrieval fails, so an attacker who can supply such a file can cause memory to accumulate. Upgrade to version 14.10.3.
