Microsoft Black Tuesday Preview, October 2010

Today, in keeping with its usual schedule, Microsoft released its Security Bulletin Advanced Notification for October, giving a preview of the security patches it intends to release next Tuesday, October 12.     This month will bring a bumper crop of 16 patches; four of these have a maximum severity rating of Critical, ten are rated Important, and two Moderate.   There are  Critical updates for all supported versions of Windows.    Two bulletins, both rated Important, affect Microsoft Office and its components, including the Mac versions, as well as the Word and Excel viewers.   The following table gives the patch breakdown by version and severity.

Windows Version Critical Important Moderate
Windows XP+SP3 3 6 1
Windows Vista 3 6 1
Windows Server 2003 2 7 1
Windows Server 2008 2 5 2
Windows 7 4 5 1
Windows Server 2008 R2 2 5 3
Microsoft Office 2

There are also two Important bulletins that affect server software: one for the SharePoint server, and one for Office Web.

Microsoft says that, of the 16 bulletins, 8 will definitely require a system reboot, and the rest may or may not, depending on the configuration of your system

As always, this information is subject to change between now and the actual release of the security bulletins on Tuesday.  I will post an updated summary after the release is made.
