Microsoft has released this month's security updates for Microsoft Windows, Microsoft Office and other company products just a second ago.
This month's updates bring 13 bulletins that fix a total of 47 vulnerabilities.
Four bulletins have received the highest severity rating of critical. This means that at least one product is affected critically by at least one of the vulnerabilities that the bulletin addresses.
The remaining ten bulletins have all received a maximum severity rating of important. Again, this means that at least one product is affected by it at this severity level.
The vulnerabilities in eight bulletins may allow remote code execution on affected systems, while three may enable an elevation of privileges, two the denial of service, and one for information disclosure.
Operating System Distribution
This section looks at individual operating system versions, and how each supported operating system is affected by this month's bulletins.
Microsoft has released a total of 13 bulletins in September 2013, of which seven affect at least one version of Microsoft Windows.
Windows XP is again the operating system with the highest count of critical vulnerabilities. All newer Microsoft operating systems share the same amount of critical vulnerabilities. As far as important rated vulnerabilities go (the second highest rating): Windows 7 takes the lead here followed by Vista and Windows 8, and then Windows RT.
It looks similar on the server side of things. Windows Server 2003 is the only server operating system affected by a critical bulletin. All other server products are only affected by important and moderate bulletins, with Windows Server 2008 R2 affected by one additional important rated bulletin.
Microsoft has released seven Office-related bulletins in September 2013. The distribution indicates that Office 2010 is the operating system with the largest number of vulnerabilities, followed by Office 2007. Both Office 2003 and Office 2013 share the same low number of vulnerabilities.
Microsoft releases a deployment guide each month that system administrators and individual users can use as a guideline to determine the update priority.
While it is usually sound to start with the critical updates and then the lesser severe updates, it may be important to distribute updates in a certain order, for instance to fix issues first that are exploited in the wild.
Priority 1 updates: MS13-068 Outlook, MS13-069 Internet Explorer and MS13-067 SharePoint Server
Priority 2 updates: Ms13-070 OLE, MS13-072 Office, Ms13-073 Excel, Ms13-076 Kernel-Mode Driver and Ms13-079 Active Directory
Priority 3 updates: Ms13-071 Windows Theme File, Ms13-074 Access, Ms13-075 Office IME (Chinese), Ms13-077 Windows SCM and Ms13-078 FrontPage.

How to download and install the September 2013 security updates
The common way to install the updates is via the operating system's built-in automatic update feature. While that is comfortable to do, it does not provide you with many controls. You cannot for instance decide the order in which updates should be installed.
The easiest way to open Windows Update is to tap on the Windows-key, enter Windows Update, and select the entry from the list of results that opens up.
You can download all patches from Microsoft's Download Center either individually, or as a monthly ISO image. An alternative to that are third party tools that you can use to download patches and updates to your system.
