Well, the point was made in my office on Friday that the upgrade was
not just snmp or sshd but that they were required to upgrade the core
operating code. This suggests to me that it's something to do with
packets or packet handling, not with services. Which makes me all the
more concerned. Of course, it will probably be something along the
lines of "When reciving a packet with such and such format with some
particular service enabled, the router might reload under specific
conditions" or some such thing that will not affect many people other
than the tier 1s who work their routers way harder than any of us
lilliputians.

I agree - this would not be a defect that would require backbone maintenance
- it's a defect that would affect edge VOIP devices, hardly core
infrastructure.

Of course, it could be that there is another more serious defect out there
that major providers have been pre-warned about and are deploying
countermeasures prior to a general disclosure (ALA SNMP vulnerabilities).

We'll have to wait and see.

I do not expect, that any carriet took this as an emergency - defect is
quite harmless (DOS in the worst case, + no exploits known, + no any
interest for anyone to do it, + VoIP gateways involved only...). Even if
someone is doing maintanance, it can be noticed by VoIP network users only.

Moreover, correct me if it was not defect in Cisco express call center (call
center @ IOS) - I can not image carriers using this (it was designed for
small businesses).

Why to get simple, relatively harmless (require ugrade in next scheduled
time, usually 1 - 3 weeks) defect as a terrible threat to everyone? Even BGP
problem was much more dangerous (and no single case known since this, so it
was not emergency as well)..
