Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

ImageMagick before 7.1.2-18 contains a memory leak vulnerability in the META reader when processing APP1JPEG input paths. Attackers can trigger this memory leak by providing specially crafted APP1JPEG image files, causing denial of service through resource exhaustion.
