Bug in NMAP Scanning suite...

["RAGHAVENDRAN H. (SSG) - CTD, Chennai." <raghavh () ctd hcltech com>]

Hi Fyodor/List:

While going through the source code for NMap, I think I found something that
may be a bug. I just thought I'd bring it to your notice.

It is in function:

struct scan_lists *getfastports(int tcpscan, int udpscan) {
  int tcpportindex = 0;
  int udpportindex = 0;

        ..
        ..
        ..

      ports->tcp_ports[tcpportindex++] = bucket;
    if (usedports[bucket] & SCAN_UDP_PORT) 
      ports->udp_ports[udpportindex++] = bucket;
  }
  if (tcpscan) 
    ports->tcp_ports[tcpportindex] = 0;
  if (udpscan) 
---------------> ! BUG HERE !    ports->tcp_ports[udpportindex] = 0;
return ports;
}

Shouldn't the marked line read as:

 ports->udp_ports[udpportindex] = 0;

i.e. tcp_ports --> udp_ports.

Regards,
Raghav
