+Subject: emulation: Limit integer arguments to 65535
+
+To guard against malicious sequences containing excessively big numbers,
+limit all parsed numbers to 16 bit range. Doing this here in the parsing
+routine is a catch-all guard; this doesn't preclude enforcing
+more stringent limits in the handlers themselves.
