Justin James gathers the information you need to make the right deploy decision when applying Microsoft's June 2012 patches in your organization.
The big news for June is the "Flame" virus. This thing is a total mess. The good news is, its intended use and targets are very specific, and chances are, if you are reading this, you aren't them (unless you are a member of certain Middle Eastern governments). The most disturbing thing for the general public is that its creators were able to forge certificates for Windows Update, but to exploit them, attackers would need to do a man-in-the-middle attack (typically done through pointing to a malicious DNS server, or attacking DNS servers) to point users to a bad Windows Update server. That's not exactly a small task, and Microsoft has already released a patch to revoke the bad certificates.
In better news, though, there was not a single security patch for Microsoft Office! Other than the annual December slow down, I do not recall this happening in a very, very long time.
This blog post is also available in the PDF format in a TechRepublic Download. Falling behind on your patch deployments, catch up with previously published Microsoft Patch Tuesday blog posts.
Security PatchesMS12-036/KB2685939 - Critical (XP, Vista, W7, 2003, 2008, 2008 R2): A flaw in Remote Desktop Protocol (RDP) allows attackers to perform remote code execution attacks. How many Windows servers allow RDP (even through the firewall)? An awful lot - get this patched ASAP. MS12-037/KB2699988 - Critical (IE6, IE7, IE8, IE9): This patch rolls up a whopping thirteen security fixes into one. One of the vulnerabilities is already publicly known, too. Needless to say, this patch is a high priority item. MS12-038/KB2706726 - Critical (.NET Framework 2.0, .NET Framework 4): Regular readers will know that I've become very down on XAML Browser Applications (XBAPs) due to security concerns. This is further reinforcement of that view. This patch plugs a remote code execution hole in XBAPs, and should be installed immediately. MS12-039/KB2707956 - Important (Lync 2010 clients, Microsoft Communicator 2007 R2): Four security vulnerabilities, one that allows for remote code execution attacks, have been found in a variety of Microsoft Lync clients and Microsoft communicator 2007 R2. It's not likely you will be in a meeting with an attacker; this patch can wait until your next scheduled patch time. MS12-040/KB2709100 - Important (Microsoft Dynamics AX 2012): The Microsoft Dynamics AX 2012 Enterprise Portal allows attackers to send email messages to users or trick them into clicking on an URL that could perform an elevation of privileges attack. Install this patch if you use Enterprise Portal. MS12-041/KB2709162 - Important (XP, Vista, W7, 2003, 2008, 2008 R2): Locally logged on users have five vulnerabilities to escalate privileges, this patch fixes them. This is a low threat issue and the patch should not be treated as an emergency. MS12-042/KB2711167 - Important (XP, W7, 2003, 2008 R2): Here's the winner for "bizarre security problem of the month": somehow, there is a pair of escalation of privileges vulnerabilities that affect XP/2003 and W7/2008 R2, but managed to miss the Vista/2008 generation of Windows. In the years that I have been writing this article each month, I never thought I'd see that! In any event, you should install this patch on schedule.
