Today Microsoft released an update to address a
vulnerability that affects all versions of the .NET Framework when used on the
Windows Server operating system.
IT professionals are advised to get the update directly from
the Microsoft Download Center. This allows us to get the update out as quickly
as possible. The update will also be released through Windows Update and
Windows Server Update services in the next few days.
Download the update.
If you use a computer at home you are not vulnerable unless
you are running a Web server.

Notification for September 2010.
