Microsoft Security Bulletins For August 2013 overview

Welcome to our analysis of Microsoft's Patch Tuesday of August 2013. The company has released a total of eight bulletins this time that patch vulnerabilities in Microsoft Windows, Microsoft Server Software, and Internet Explorer.

Three of the bulletins have received a maximum severity rating of critical, the highest rating available, while the remaining five bulletins have all received one of important, the second highest rating.

What this means is that there is at least one product that is affected by a vulnerability this way, while other products may have received the same or a lower severity rating.

The eight bulletins that Microsoft is releasing fix a total of 23 different vulnerabilities in Microsoft products.

Operating System Distribution

This section looks at individual operating systems and how each one is affected by vulnerabilities that Microsoft fixed on this Patch Tuesday in August 2013.

Microsoft has released a total of eight bulletins for various client and server operating systems, and other software such as Microsoft Office or Internet Explorer. While Internet Explorer is included in Windows, it is handled separately by Microsoft in regards to vulnerabilities.

Windows XP is taking the crown this time as it is affected by more critical vulnerabilities than all other client operating systems. All other systems, Vista, 7 and 8, share the same vulnerability ratings.

You find the same distribution on the server side, with Windows Server 2003 affected by a single critical vulnerability, while newer server operating systems share the same vulnerability scores.

  • Windows XP: 2 critical, 2 important
  • Windows Vista: 1 critical, 3 important
  • Windows 7:  1 critical, 3 important
  • Windows 8:  1 critical, 3 important
  • Windows RT: 1 critical, 2 important
  • Windows Server 2003: 1 critical, 2 important, 1 moderate
  • Windows Server 2008: 4 important, 1 moderate
  • Windows server 2008 R2: 4 important, 1 moderate
  • Windows Server 2012: 4 important, 1 moderate

Deployment Guide

Microsoft releases a deployment priority guide each month to aid system administrators and users in prioritizing updates. It is usually the case that critical updates should be deployed first before other updates are deployed.

Microsoft suggests the following deployment priority:

  • Tier 1: MS13-059 update for Internet Explorer and MS13-060 which updates the Unicode Scripts Processor.
  • Tier 2: MS13-061, an update for Exchange Server, Ms13-062 updating Remote Procedure Call, and Ms13-063 patching Windows Kernel.
  • Tier 3: Ms13-066 an update for Active Directory Federation Services, Ms13-064 updating Windows NAT driver, and Ms13-065 updating ICMPv6.

How to download and install the August 2013 security updates

windows update august 2013

Most Windows users have automatic updates enabled on their systems, which means that important updates do get downloaded and installed automatically on their systems. While that is the case, it is often a good idea to check for updates manually shortly after this article goes live as you may have to wait hours and sometimes even days before the updates get installed otherwise.

Most Windows users can do the following to check for updates.

  1. Tap on the Windows-key and type Windows Update in the form that opens.
  2. Select Windows Update from the list of results.
  3. Click on check for updates there to run a manual update check.
  4. Look at the updates found and click on install updates afterwards.
  5. It is usually required to restart the PC in the end to complete the process.

Experienced users and system administrators do not install updates right away. The core reason for this is that updates may include bugs or issues that Microsoft's quality testing has missed. That's why updates can also be downloaded from Microsoft directly.

This is not only useful when you want to test updates in a safe environment, a virtual machine or test system for example, but also when you need to deploy them on a larger scale. If you are using Windows Update to download updates, you are wasting bandwidth as each PC is downloading the same updates (provided they are running the same version of Windows).

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.

    Hallo Martin, Thanks for your monthly update which who I understand what I am doing when I am updating. Thru your guiding explanation it even makes sense! :-)

    This mouth white the new page style (the white of the page is just white enough and the letters are nice/calming to read) on main 22 inch monitor I am enjoying your website even more.

    There is only one thing I am wondering about the thumbnail (picture) from this page on the page before this. The page with the short summery of what’s in the article’s.
    Why I do not understand why do you need those thumbnails? There to small to really show me anything from this page, so personally up-til right now I think there a waste of effort.

This update is rated critical for client and important for server operating systems and affects all listed versions of the Internet Explorer web browser and all currently supported Windows operating systems (server core installations excluded).

    Relax, You Don’t Have to Fix Every Vulnerability

    Here’s an idea: stop fixing every vulnerability you read about. The best thing to do, it turns out, is to look at the vulnerabilities that are in both Metasploit and the Exploit Database and fix those. That gives you the highest chance of fixing bugs that are likely to be used in an actual attack…
