  Security Bug in Alcatel Speed Touch Home ADSL Modem (DoS)
------------------------------------------------------------------------

SUMMARY

 <http://www.alcatel.com/consumer/dsl/prodhome.htm> Alcatel Speed Touch
Home ADSL Modem contains a security vulnerability that allows internal
attackers to cause the modem to crash, by simply scanning it using NMap.

DETAILS

Vulnerable systems:
Alcatel Speed Touch Home ADSL Modem firmware version 8706

By scanning your Alcatel Speed Touch Home ADSL Modem from its internal
network address (10.0.0.0 subnet) it is possible to cause the modem to
crash. Since this address space is outside the normal used network
address, most modems should be safe, however, the crash can be caused by
spoofed packets allowing crashing of internal connected modems, i.e. if
the modem is connected on a local physical network subnet, and a
vulnerable modem is present.
