According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
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}’ />. (CVE-2021-39212)Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

"According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :
- 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`
