      Netopia Timbuktu Remote Buffer Overflow
    ------------------------------------------------------------------------

    SUMMARY

    The <http://www.netopia.com> Timbuktu software is shipped as "a
    client/server application that allows remote users to access the desktop
    of a host system". The server component of this application is vulnerable
    to a remote buffer overflow vulnerability that, when exploited, causes the
    server process to crash.

    DETAILS

    Vulnerable Systems:
     * Timbuktu version 7.0.3

    Immune Systems:
     * Timbuktu version 7.0.4

    The server process runs with root privileges on the host Mac OS X and
    listens for client connections on TCP port 407. By making a number of
    concurrent connections to this port and repeatedly sending a particular
    string of data, a memory buffer is overwritten and the server process
    crashes.

    CVE Information:
     <http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0810>
    CAN-2004-0810
