It is the second Tuesday of the month and we all know what that means: Microsoft Patch Day. Microsoft has released a total of ten security bulletins this month that address security related issues in products such as Microsoft Windows, Internet Explorer, Microsoft Office or Windows Essentials. The ten bulletins address a total of 33 different vulnerabilities.
Two bulletins have received the highest severity rating of critical while the remaining eight received important ratings. What this means is that at least one product received the rating while other affected versions of the product may have received the same or a lower rating.
Security update MS13-038 resolves a 0-day security vulnerability that affects Microsoft's Internet Explorer 8 on all supported operating systems. Microsoft has released a fix-it patch recently to address the issue.
The second critical bulletin of the month is a cumulative update for Microsoft's web browser that resolves 11 different security related vulnerabilities.
Operating system distribution
It is often the case that desktop and also server operating system versions are affected in different ways by the vulnerabilities. Here we look at the distribution of severity ratings across all desktop and server operating systems.
As you can see, all desktop versions of Windows share the same severity rating with the exception of Windows 8 and Windows RT. As far as servers go, the picture is a little bit different. Here it is Windows Server 2012 that is affected more severely than previous versions of the server operating system.
Microsoft recommends to deploy the bulletins in the following order:
Non-security related updates
Non-security related updates have been released since the last patch Tuesday as well. The following list provides you with an overview of the updates that Microsoft has released in that time.
How to download and install the May 2013 security updates
The easiest way to obtain all security updates is to use Windows Update. Windows XP to Windows 7 users can use the search menu to load Windows Update on their system while Windows 8 users need to search for it on the start screen instead.
You may need to click on the check for updates button on the page as the updates may not have been picked up automatically by the operating system.
If you want more control over the process head over to Microsoft's Download Center. I recommend you enter the name of the bulletin into the search on the page as Microsoft seems to have modified the download page so that you cannot sort security updates by date anymore.Advertisement
