From Red Hat Security Advisory 2019:0633 :
An update for ghostscript is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
The Ghostscript suite contains utilities for rendering PostScript and PDF documents. Ghostscript translates PostScript code to common bitmap formats so that the code can be displayed or printed.
Security Fix(es) :
ghostscript: superexec operator is available (700585) (CVE-2019-3835)
ghostscript: forceput in DefineResource is still accessible (700576) (CVE-2019-3838)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
