Summary
It was found that RHSA-2018:2918 did not fully fix CVE-2018-16509. An attacker could possibly exploit another variant of the flaw and bypass the -dSAFER protection to, for example, execute arbitrary shell commands via a specially crafted PostScript document. This only affects ghostscript 9.07 as shipped with Red Hat Enterprise Linux 7.
