COMMAND

    tcp/ip

SYSTEMS AFFECTED

    MAC OS up to 8.x

PROBLEM

    Spikeman found following.  You  can kill all the bandwidth  out of
    MacOS up to 8.*, by  finding a open port (  only 1 ) and by  using
    synk command line:

        synk 0 ip open_port then_the_next_port

    MacOS tcp/ip stack can't handle synfloods and inturn it takes  all
    bandwidth alway from  that box.... keep  it for 5  mins or so  and
    all conn's from the box _should_ die ( telnets/ftps/ircs/etc )...

    Nothing yet.
