CVE-2021-39212 is a low-severity vulnerability rated 3.6/10 on the CVSS scale. 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.

EPSS estimates a 0.33% chance of exploitation in the next 30 days.

Description

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}" />.
