How to fix?

Upgrade RHEL:7 ghostscript-cups to version 0:9.07-31.el7_6.11 or higher.
This issue was patched in RHSA-2019:1017.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ghostscript-cups package and not the ghostscript-cups package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable.
