Description

A flaw was found in ImageMagick. A remote attacker can exploit this issue by providing a specially crafted CMYK image that is processed into a PDF document using JPEG2000 compression. This causes the PDF writer to access previously released memory (a use-after-free condition), which can crash the application and result in a Denial of Service (DoS).
