We are proactively assisting our Managed Network Service clients who are affected by the latest serious security flaw from Microsoft. Windows Server 2008 and Windows Vista are at risk for a security flaw which enables malicious people to crash your computer by simply sending it one packet of information.
The temporary fix for the flaw is detailed here: http://blogs.zdnet.com/security/?p=4373&tag=nl.e539
If your computer is behind a firewall, as most are, you are at lower risk for this flaw and if your computer is not running Server 2008 or Vista, you are also not affected. Feel free to contact our Support Center at 262-522-8226 if you have questions or concerns.
