ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-189 and 6.9.13-44, when Magick parses an XML file it is possible that a single zero byte is written out of the bounds. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.
