Upgrade RHEL:8 libgs-devel to version 0:9.25-2.el8_0.3 or higher.

NVD Description
Note: Versions mentioned in the description apply only to the upstream libgs-devel package and not the libgs-devel package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
A flaw was found in all ghostscript versions 9.x before 9.50, in the .setuserparams2 procedure where it did not properly secure its privileged calls, enabling scripts to bypass -dSAFER restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.
