Malformed Packet Causes Cisco Router DoS
MoreBeer writes "Patch 'em if you've got 'em... Cisco Security Advisory: Cisco IOS Malformed OSPF Packet Causes Reload states that a malformed OSPF packet can cause a router 'reload' (reboot). Vulnerable IOS versions include 12.0S, 12.2, and 12.3 ... If you're not screening OSPF at your perimeter and using OSPF Authentication, now would be a GREAT time to start."
at the risk of stating the obvious: if you were a new customer and went to a company's site and it was splattered with all manner of warnings, update calls, and exploit workarounds....would you buy that product?
If you have a cisco, you should already know where the errata, update, exploit-watch pages are and read them everyday. You should already know this. Why would cisco put that shit on the front page?
No, in this case, I don't believe you may :-)
I can't get 1 hour support for an Intel/OBSD server from a service provider with a worldwide reputation. If I do get such support, it would have to be guaranteed that they would have every combination of T1 and FastEther card in stock, power supply, etc that would possibly break.
Sometimes standardization on one vendor worldwide is a GOOD thing. It's no problem to find Cisco support in Europe, South America, North America, Asia, etc. If a company has a router in Singapore and that router fails, would they rather try to find support for an OpenBSD whitebox, or call 1800-Go-Cisco and have someone go replace it immediately? Many international offices don't have full-time IT staffing, so there may not be anyone within an 8 hour plane flight capable of fixing the issue within the company.
Cisco and the other infrastructure providers make a lot of money for a very good reason, people trust them and can get support anywhere they happen to be.
Certainly, for a home user or single office with 20 people, one of whom is a BSD junkie, a Unix based router might be a fine idea. However for global organizations with multiple high-bandwidth links between branches, for example, for whom downtime costs many thousands of dollars per hour, there aren't very many options. It's a good thing that what options there are are very solid.
