ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications. In affected versions and in certain cases, Postscript files could be read and written when specifically excluded by a module policy in policy.xml. ex. <policy domain=“module” rights=“none” pattern=“PS” />. The issue has been resolved in ImageMagick 7.1.0-7 and in 6.9.12-22. Fortunately, in the wild, few users utilize the module policy and instead use the coder policy that is also our workaround recommendation: <policy domain=“coder” rights=“none” pattern=“{PS,EPI,EPS,EPSF,EPSI}” />.
