Update on the SMB vulnerability situation

We’d like to
give everyone an update on the situation surrounding the new Microsoft
Server Message Block Version 2 (SMBv2) vulnerability affecting Windows
Vista and Windows Server 2008.

• Easy way to disable SMBv2
• First exploit for code execution released to small number of companies
• Mitigations that help prevent attacks
• Status of fixes

Easy way to disable SMBv2

Until the security update is released, the best way to protect
systems from this vulnerability is to disable support for version 2 of
the SMB protocol. The security advisory was updated yesterday with a
link to the Microsoft Fix It package that disables SMBv2 and then stops
and starts the Server service. (This initial Fix It might prompt you to
also restart the Browser service.)  You can also click here: http://go.microsoft.com/?linkid=9683379

I suggest you read this entire article before you install this.
