How to fix?

Upgrade Centos:7 ghostscript-cups to version 0:9.07-31.el7_6.10 or higher.

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 Centos. See How to fix? for Centos:7 relevant fixed versions and status.

It was found that the forceput operator could be extracted from the DefineResource method in ghostscript before 9.27. 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.
