  "details" : [ "ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to both 6.9.13-52 and 7.1.2-27, processing an extremely large JNX file on 32-bit platforms can cause an integer overflow, leading to a heap buffer over-write. This issue has been fixed in versions 6.9.13-52 and 7.1.2-27.", "A flaw was found in ImageMagick. When processing extremely large JNX image files on 32-bit systems, an attacker could trigger an integer overflow. This overflow leads to a heap buffer over-write, which can cause the application to crash, resulting in a denial of service." ],
  "statement" : "This Moderate impact flaw in ImageMagick affects 32-bit systems, where processing an exceptionally large JNX image file can trigger an integer overflow. This leads to a heap buffer overwrite, causing a denial of service. The vulnerability requires local access and has high attack complexity, limiting its broader exploitability.",
