    A user of ours has reported that the D-Link DI-614+
    Wireless router/firewall is vulnerable to several old,
    well known vulnerablities.  The user was able to reproduce
    the problem multiple times with consistent results.  Not
    having the equipment, we have NOT reproduced these ourselves,
    and would appreciate if anyone can corroborate these
    problems.
    
    The vendor was notified on March 13th and has not responded
    back.
    
    Both tests causing problems were reproduced using the Nessus
    test suite. Test IDs are Nessus test ID numbers and are
    supplied for reference.
    
    Nestea:  A Nestea attack applied to the device causes the
         device to spontaneously reboot. The device is out of
         operation for only a few seconds and is then back in
         service with no other known impact.

    Linux 0 length fragment bug: Sending the appropriate packet
         causes the device to crash requiring a power off-on cycle
         to recover.

    If anyone can support that their device does or does not behave
    similarly it would be appreciated.
