Synopsis

The remote Windows host contains a library that is affected by a security bypass vulnerability.

Description

The version of Artifex Ghostscript installed on the remote Windows host is prior to 9.27. It is, therefore, affected by a security bypass vulnerability due to some privileged operators remained accessible from various places after the CVE-2019-6116 fix.
