SYSTEMS AFFECTED

    GoodTech Systems FTP 3.0.1.2.1.0 (evaluation build)

PROBLEM

    Peter Grundl (Defcom  Labs Advisory def-2001-03)  found following.
    The GoodTech FTP server does  not properly free ressources.   This
    can result  in the  FTP server  either crashing  or displaying its
    banner and immediately disconnecting the user.

    Connecting approx.  2060-2080 times  (one at  a time)  to the  FTP
    server, using sockets,  can result in  the server either  crashing
    or refusing to accept more connections.  This appears to depend on
    the rate the connections are received  by the FTP server.  A  fast
    flood results in a crash, whereas a slow flood results in the  ftp
    banner being displayed and an immediate disconnect.

SOLUTION

    Obtain the latest build from the vendor:
