Machine-written summary

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

Magick.NET Q16 packages before 14.11.1 leak a temporary image in the ASHLAR coder when an action fails, which can lead to an out-of-memory condition. The source gives few details about what an attacker would need to trigger this. Upgrade to version 14.11.1 or later.
