Microsoft a few minutes ago has pushed out nine security updates as part of this month's update for the Windows operating system. The security bulletins for August 2012 address vulnerabilities in programs such as Microsoft Windows, Internet Explorer, Microsoft Office, Microsoft Exchange and Microsoft SQL Server. Five of the bulletins have received a maximum severity rating of critical, the highest available rating for vulnerabilities, while the remaining four bulletins a rating of important.
Maximum severity rating means that there is at least one version of a product that has received the rating. Critical vulnerabilities allow code execution on a user system without user interaction. Lets take a look at the different operating systems and their severity ratings:
As you can see, newer versions of Windows in this particular case face less severe vulnerabilities than older versions. While this does not have to be always the case, it is usually the case. Sometimes though, newer operating systems may be vulnerable while oder are not due to added features in those newer systems.
The updates are already available on Windows Update. You may need to check for updates manually for the operating system to catch the updates.
You can alternatively download the updates from Microsoft's Download Center where they are available for all affected products both as standalone patches and a monthly ISO image.
