Cisco Security Advisory: Cisco IOS Malformed OSPF Packet Causes Reload
Cisco just released a Security Advisory about a possible DoS condition in Cisco devices that have OSPF enabled.
According to Cisco:
"A Cisco device running Internetwork Operating System (IOS) ® and enabled for the Open Shortest Path First (OSPF) protocol is vulnerable to a Denial of Service (DoS) attack from a malformed OSPF packet. The OSPF protocol is not enabled by default.
The vulnerability is only present in Cisco IOS release trains based on 12.0S, 12.2, and 12.3. Releases based on 12.0, 12.1 mainlines, and all Cisco IOS images prior to 12.0 are not affected.
Cisco has made free software available to address this vulnerability.
There are workarounds available to mitigate the effects."

If do you ever had problems with spywares and related, be careful when choosing the right tools. The worst thing is that if you have a spyware in your computer, a lot of Anti-spywares tools pop-ups will appear in your window, offering the products. Be very very careful...!
I usually have a set of tools that I trust to clean up a computer, as many of you. So, if you are in doubt, drop us a line.
