+
+Successful exploitation has been demonstrated on 32-bit Linux/glibc
+systems with ASLR. Under lab conditions, the attack requires on
+average 6-8 hours of continuous connections up to the maximum the
+server will accept. Exploitation on 64-bit systems is believed to be
+possible but has not been demonstrated at this time. It's likely that
+these attacks will be improved upon.</p> + </impact> + <workaround> + <p>There is no known workaround at this time.
