Justin James gathers the information you need to make the right decision when applying Microsoft's July 2011 patches in your organization.
As far as these things go, July 2011 is nice and easy compared to the last monster Patch Tuesday in June. The big news is that Internet Explorer 9 is now coming down the pike via WSUS. While I've found IE9 to be a massive improvement over IE8, you will want to make sure that your testing is complete before moving to IE9. Once again, our old friend the library loading from network locations bug has struck again, this time with Visio 2003. Why hasn't Microsoft fixed all these by now? I feel like a year from now they will still be finding this with, say, Publisher or Groove or something else that isn't as widely used. This blog post is also available in PDF format in a TechRepublic download. Falling behind on your patch deployments, catch up with previously published Microsoft Patch Tuesday blog posts.
Security PatchesMS11-053/KB2532531 - Critical (Vista, W7): The Windows Bluetooth stack can allow remote code execution attacks when provided with bad packets. Needless to say, this is a critical issue for any computer with Bluetooth installed and enabled. Microsoft says to make sure that you install KB2552343 before installing this update. 328KB - 464KB MS11-054/KB2555917 - Important (XP, Vista, W7, 2003, 2008, 2008 R2): This patch solves fifteen (yes, fifteen) escalation of privilege vulnerabilities in Windows. They all require the attacker to be logged on locally, which mitigates much of their risk, thankfully. You should install this patch at your usual time. 1.1MB - 4.2MB MS11-055/KB2560847 - Important (Visio 2003 SP3): Remember our old friend the library loading bug, which can allow remote code execution attacks by opening files in network locations? This is another patch for this bug, this time in Visio 2003 SP3. Install the patch if you have this older version of Visio installed. 1.0MB MS11-056/KB2507938: Important (XP, Vista, W7, 2003, 2008, 2008 R2): Another patch for escalation of privilege issues, five fixed with this patch, this time in the Client/Server Run-time Subsystem. Again, these holes need the attacker to be locally logged on to exploit them, and the patch can wait until your normal patch time. 307KB - 4.0MB
