Hello all. As part of our usual cycle of monthly updates, today Microsoft is releasing 14 security bulletins, addressing 34 vulnerabilities. Eight of those bulletins have a Critical severity rating, and we consider four of those to be high-priority deployments:
Currently none of the vulnerabilities addressed has been observed under exploit in the wild. In the following video, Jerry Bryant and Adrian Stone talk about why these four are at the top of our priority list:

The six other bulletins offered this month are rated Important. Two of the Important-level bulletins, MS10-047 and MS10-048, are Windows Kernel updates.
As always, Microsoft recommends that customers test and deploy all security updates as soon as they can.
For a closer look at some of the issues involved in these bulletins, our Security Research & Defense (SRD) team writes about MS10-048, MS10-049, and MS10-054 today on its blog.
We're also releasing Security Advisory 2264072 with this update. This advisory addresses the potential for attacks that leverage the Windows Service Isolation feature to gain elevation of privilege. In turn, the release of MS10-049 closes Security Advisory 977377, which described a spoofing vulnerability addressed in today's release. When early investigation revealed that this vulnerability is an industry-wide problem, Microsoft worked on a coordinated response with our partners in the Internet Consortium for Advancement of Security on the Internet (ICASI). A new standard was developed, RFC 5746, which allows developers of both client and server applications to address this vulnerability.
More information about the security updates can be found on the Microsoft Security Bulletin summary webpage. Our Exploitability Index provides additional information to help customers prioritize deployment of the monthly security bulletins.
On August 2, we released MS10-046 out of band in response to a new zero-day vulnerability being exploited by the Stuxnet family of malware. This month, we have added Stuxnet and several other malware to the Malicious Software Removal Tool (MSRT) in order to help clean up systems that may have been impacted. Here's the full list of new malware being added:
