Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Magick.NET packages, including Magick.NET-Q16-x64 and related builds, are vulnerable in versions before 14.10.3 because of a memory leak in the ASHLAR image writer. An attacker who can supply a crafted image that is written with this encoder can exhaust process memory. Upgrade to version 14.10.3 or later.
