Microsoft Patch Tuesday Preview, June 2011

In keeping with its usual schedule, Microsoft today released its Security Bulletin Advanced Notification for June, previewing the security fixes it plans to release next Tuesday, June  14.  The company plans to release a total of 16 security bulletins; thirteen of these are for Windows, one is for Microsoft Office (including the Mac version), and the rest are for other Microsoft packages..  There are nine bulletins rated Critical, and seven rated Important.  All supported releases of Windows are affected, each with several Critical vulnerabilities; the following table gives the breakdown by Windows version.

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

Of the remaining bulletins,  Silverlight and Forefront (a security application!) have a Critical vulnerability apiece; Office and Visual Studio have vulnerabilties rated Important.

Microsoft’s announcement says that nine of these bulletins will definitely require a system restart; the rest may require a restart, depending on the configuration of your system.

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.
