+  * Fix CVE-2018-19134: 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.
+  * Fix CVE-2018-19478: Attempting to open a carefully crafted PDF file results in
+    long-running computation.
