Severity ratings do not apply to this update for the specified software because the known attack vectors for the vulnerability discussed in this bulletin are blocked in a default configuration. However, as a defense-in-depth measure, Microsoft recommends that customers of this software apply this security update.

Microsoft Patch Tuesday Preview, October 2012

The other five bulletins affect a variety of Microsoft products.  There are three bulletins, including the one bulletin rated Critical, that affect Microsoft Office and its components.  One Important bulletin applies to Microsoft’s SQL Server (all versions).  These Microsoft server products also have patches scheduled:

  • Share Point Server

Complete details are given in the Security Bulletin Advanced Notification.  Microsoft says that the two Windows patches will definitely require a system restart; the others may require one, depending on the system’s configuration.

As always, this information is subject to change until the security bulletins are actually released next Tuesday.  I’ll post another note here once they are available.
