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 crafted image can bypass an ImageMagick security policy that uses coder as its domain, potentially allowing data prohibited by the policy to be read. This issue is fixed in versions 7.1.2-31 and 6.9.13-56.
