+    Several security vulnerabilities were discovered in Ghostscript, an
+    interpreter for the PostScript language, which could result in denial of
+    service, the creation of files or the execution of arbitrary code if a
+    malformed Postscript file is processed (despite the dSAFER sandbox being
+    enabled).
