Yes, of course, mldonkey is backdoored, but I don't see why it would
open two other ports just for that since it is already listening on
standard ports that can be extended for that silently :)

In fact, mldonkey opens another port than the one specified in its
configuration file just to cope with a bug that appeared in former
linux clients 13842 = 18 + 256 * 54 is the byte reversed equivalent of 
4662 = 18 * 256 + 54. The other port for udp is randomly generated.
