+Subject: [PATCH 1/5] Bug 699795: add operand checking to
+ .setnativefontmapbuilt
+
+.setnativefontmapbuilt .forceputs a value into systemdict - it is intended
+to be a boolean, but in this case was being called with a compound object
+(a dictionary). Such an object, in local VM, being forced into systemdict
+would then confuse the garbager, since it could be restored away with the
+reference remaining.
+
+This adds operand checking, so .setnativefontmapbuilt will simply ignore
+anything other than a boolean value, and also removes the definition of
+.setnativefontmapbuilt after use, since it is only used in two, closely
+related places.
+
+CVE: CVE-2018-17961
+Upstream-Status: Backport [git://git.ghostscript.com/ghostpdl.git]
