Doc Text:
A flaw was found in ImageMagick. A memory leak vulnerability exists in the JNG (JPEG Network Graphics) encoder when the application fails to open a blob. A remote attacker could exploit this by providing specially crafted malformed JNG files, leading to resource exhaustion and a denial of service (DoS) for the affected system.

Description OSIDB Bzimport 2026-07-15 12:04:27 UTC
ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the JNG encoder when a blob cannot be opened. Attackers can trigger the memory leak by providing malformed JNG files that fail blob operations, causing resource exhaustion.
