Machine-written summary

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

Magick.NET-Q16 packages (AnyCPU, HDRI and OpenMP variants) before 14.11.0 have a heap buffer overflow in the NewXMLTree method, which writes a single zero byte out of bounds. The source gives few details on what an attacker needs, but the flaw can crash the process. Upgrade to version 14.11.0 or later.

Written 9 Nov 2026.
