Doc Text:
A flaw was found in ImageMagick. A remote attacker can cause a Denial of Service (DoS) by supplying a specially crafted image file to be encoded into the JPEG Network Graphics (JNG) format. Due to a failure to properly release allocated memory in the JNG encoder, processing these files can lead to memory exhaustion and service instability.

Description OSIDB Bzimport 2026-10-25 13:34:25 UTC
ImageMagick before 6.9.13-58 and 7.x before 7.1.2-33 contains a memory leak in the JNG encoder that fails to release allocated memory when processing a crafted image. Attackers can supply crafted images that are encoded to JNG to leak memory, potentially causing resource exhaustion and a limited denial of service.
