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)

Red Hat would like to thank Tavis Ormandy (Google Project Zero) for
reporting this issue.");
