In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of failure to check whether the Implementation of a pattern dictionary was a structure type.

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.
