+	  <p>Prevent a class of security bugs caused by treating the contents
+	    of a buffer chunk as if they were a NUL-terminated string. At least
+	    one such bug seems to be present in all currently used versions of
+	    Tor, and would allow an attacker to remotely crash most Tor
+	    instances, especially those compiled with extra compiler hardening.
+	    With this defense in place, such bugs can't crash Tor, though we
+	    should still fix them as they occur. Closes ticket 20384
+	    (TROVE-2016-10-001).</p>
