Machine-written summary

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

Magick.NET-Q16 packages (all variants) before 14.12.0 are affected. A deeply nested FX expression causes a stack overflow in the expression parser, crashing the process. The source gives few details on what access an attacker needs. Upgrade to 14.12.0 or later, and until then avoid passing untrusted FX expressions to the library.

Written 9 Nov 2026.
