ghostscript: Fix CVE-2019-6116

Browse Source 
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.
