Description

The remote Fedora 33 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2021-4c57a892d1 advisory.

 - Kramdown before 2.3.1 does not restrict Rouge formatters to the Rouge::Formatters namespace, and thus arbitrary classes can be instantiated. (CVE-2021-28834)
