  "details" : [ "ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a stack buffer overflow vulnerability exists in the MNG encoder. There is a bounds checks missing that could corrupting the stack with attacker-controlled data. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.", "A flaw was found in ImageMagick. Processing a specially crafted image with the MNG encoder can cause a stack-based buffer overflow due to a missing bounds check, leading to a denial of service and potentially arbitrary code execution." ],
  "statement" : "To exploit this issue, an attacker needs to convince a user to process a specially crafted file that makes ImageMagick use the MNG encoder.\nDefault Red Hat Enterprise Linux security features, including SELinux enforcement, Address Space Layout Randomization (ASLR) and NX (No-Execute) stack protection, significantly increase the difficulty of achieving arbitrary code execution, limiting the impact of this vulnerability to a denial of service.\nDue to these reasons, this vulnerability has been rated with a moderate severity.",

If ImageMagick is deployed in a way that it processes files from untrusted sources automatically, consider running the application inside a container or a restricted sandbox environment to limit the potential security impact.",
