Updated

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-27, the BGR decoder does not check for an end-of-file in every location so a crafted image could result in an heap buffer over-read. This issue has been fixed in version 7.1.2-27.
