Summary:Check the version of ghostscript

Vulnerability Insight:
The Ghostscript suite contains utilities for

to common bitmap formats so that the code can be displayed or printed.

Security Fix(es):

* It was discovered that the ghostscript /invalidaccess checks fail under
certain conditions. An attacker could possibly exploit this to bypass the
- -dSAFER protection and, for example, execute arbitrary shell commands via a
specially crafted PostScript document. (CVE-2018-16509)

* ghostscript: LockDistillerParams type confusion (699656) (CVE-2018-15910)
