ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-31 and 6.9.13-56, a missing security-policy check in the CUT encoder allows a crafted local encoding operation to read data that policy should deny and can also cause a crash. This issue is fixed in versions 7.1.2-31 and 6.9.13-56.
