+	<blockquote cite="https://www.asterisk.org/downloads/security-advisories">
+	  <p>A select set of SIP messages create a dialog in Asterisk.
+	  Those SIP messages must contain a contact header. For
+	  those messages, if the header was not present and using
+	  the PJSIP channel driver, it would cause Asterisk to
+	  crash. The severity of this vulnerability is somewhat
+	  mitigated if authentication is enabled. If authentication
+	  is enabled a user would have to first be authorized before
+	  reaching the crash point.</p>
