ImageMagick has an Out-of-Bounds write of a zero byte in its X11 display interaction

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-18 and 6.9.13-43, an out-of-bounds write of a zero byte exists in the X11 `display` interaction path that could lead to a crash. Versions 7.1.2-18 and 6.9.13-43 patch the issue.
