Microsoft Patch Tuesday Preview, January 2012

Today, in keeping with its usual schedule,  Microsoft released its Security Bulletin Advanced Notification for January, previewing the security fixes it intends to release next Tuesday, January 10.   Microsoft plans to release seven security bulletins this month; six are for Windows, and one is for Microsoft’s Developer Tools (not identified more specifically).   One Windows patch has a maximum severity rating of Critical; the other five are rated Important.  All  supported versions of Windows are affected.   The table below shows the breakdown of patches by Windows version and severity:

Windows Version Critical Important
Windows XP+SP3 1 5
Windows Vista 1 4
Windows Server 2003 1 5
Windows Server 2008 1 4
Windows 7 4
Windows Server 2008 R2 4

The patch for Developer Tools has an Important severity rating.

According to Microsoft, four of the Windows bulletins will require a system restart, and the other bulletins may require one, depending on your system’s configuration.

As always, this information is subject to change between now and the actual release of the bulletins next Tuesday.  I will post a note here once the actual updates are available.
