Folks, please be aware of the advisories we posted on multiple CBOS 
issues affecting those devices at http://www.cisco.com/go/psirt/.

Despite the fact that the advisories are from last winter, there are
still a lot of DSL customers that have not been upgraded. Those CPEs 
will continue to be vulnerable to the URI used by the "Code Red" worm.  
The device will *NOT* become a vector for infection.  The device simply 
"locks up" due to the malformed HTTP request, and the power has to be 
cycled for it to resume service.

Thanks, Lucy, for making sure folks were aware of that problem.
