AnalysisAIv1 – Jul 26, 2026

Heap buffer over-write in Magick.NET versions before 14.15.0 on 32-bit platforms when processing extremely large JNX files can lead to a denial-of-service condition by crashing the application. The vulnerability resides in the bundled ImageMagick library's JNX decoder, where an integer overflow occurs during file handling. Exploitation requires the attacker to supply a malicious JNX file to a locally running .NET application using Magick.NET; no public exploit or active exploitation is known.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Integer Overflow MEDIUM

Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
