## Overview

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains a use after free vulnerability in the PDF writer when writing CMYK images with JPEG2000 compression. Attackers can supply a crafted CMYK image that, when written to PDF with JPEG2000 compression, causes freed memory to be reused, potentially crashing the process.
