Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Magick.NET packages up to version 14.9.0 are affected by a flaw in the CLAHE function, where zero-sized tiles cause out-of-bounds memory access and division by zero. An attacker who can supply crafted CLAHE parameters or small images can crash the process or exhaust memory, causing denial of service. No fixed version is listed.
