Description OSIDB Bzimport 2026-10-12 16:53:13 UTC
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an incomplete cleanup flaw in the JNG decoder that fails to remove temporary files when processing crafted input. Attackers can submit crafted JNG files for processing to repeatedly leak temporary files, consuming disk space and degrading availability.
