ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-19 and 6.9.13-44, the viff encoder contains an integer truncation/wraparound issue on 32-bit builds that could trigger an out of bounds heap write, potentially causing a crash. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.
