Microsoft has released a new set of updates and patches for its software product a couple of seconds ago. The company releases security updates in one go on every second Tuesday of the month, and only breaks that habit for critical security vulnerabilities that are exploited in the wild.
Today eight bulletins have been published by the company that fix security vulnerabilities in Microsoft Windows and Office, Internet Explorer, Microsoft Server Software, the Microsoft .Net Framework, and Microsoft Silverlight.
Four of the vulnerabilities have received the highest severity rating of critical, and they all affect the Microsoft Windows operating system.
The remaining four bulletins have received a maximum severity rating of important, the second highest rating. Three of them affect Microsoft Office, one Microsoft Server Software, and one Microsoft Silverlight.
Note: Highest or maximum severity rating means that at least one product has received that rating. Other products may have received the same rating, a lower rating, or may not be affected by a particular vulnerability at all.
The update for Internet Explorer will fix the critical vulnerability that came to light earlier this month.
The eight bulletins released this month fix a total of 26 different vulnerabilities in Microsoft products.
Operating System Distribution
All Windows client operating system,s with the exception of Windows RT and the not yet released Windows 8.1 and Windows RT 8.1 are affected by four bulletins that have received a vulnerability rating of critical.
The same is true for server versions of Windows, as all supported Windows Server editions are affected by the critically rated and one moderately rated security bulletin.
As far as Microsoft Office is concerned, two bulletins have been released this Patch Tuesday that affect the application. Only Microsoft Office 2007 and Microsoft Office for Mac are affected by both bulletins, while all other supported Office versions are only affected by one.
Each month, Microsoft releases a bulletin deployment guide that aims to help system and network administrators, and individual interested users alike, determine the update priority of each bulletin released.
While there is no obligation to do so, it is usually best to follow the guide. It usually suggests to install patches that protect against critical vulnerabilities first, but those too may receive different priorities in regards to deployment.

How to download and install the October 2013 security updates
The updates will be deployed automatically on most user systems by the operating system's automatic update feature. While that is the recommended installation method on most systems, some users may want full control over the update process, which automatic updates does not offer.
This is also the case for businesses and organizations who need to test updates before they are deployed on a computer network.
Last but not least, this is also the way to go if updates need to be deployed on systems without direct Internet connection.
All security patches can be downloaded from Microsoft's Download Center either as standalone update downloads, or in form of a monthly ISO image that contains all security patches for that month.
Another alternative to that are third party tools that download updates and patches automatically to the system.
