+	  <p>
+	    fetchmail's SMTP client, when configured to authenticate, is
+	    susceptible to a protocol violation where, when a trusted but
+	    malicious or malfunctioning SMTP server responds to an
+	    authentication request with a "334" code but without a following
+	    blank on the line, it will attempt to start reading from memory
+	    address 0x1 to parse the server's SASL challenge. This address is
+	    constant and not under the attacker's control. This event will
+	    usually cause a crash of fetchmail.
+	  </p>
