An update to the update: Apparently the original Knowledge Base article (KB2901549) for these updates is finally on line and clarifies that they are reliability updates vice security related updates.
The update, which apples to Internet Explorer 11 on Windows 8.1 (Standard and RT) and Windows Server 2012 R2, refers to Microsoft Security Bulletin MS13-080.
That security bulletin was related to a cumulative update for Internet Explorer which was rolled out during the October 2013 Patch Tuesday. The cumulative update addressed an IE11 security issue that was published back in in September, Microsoft Security Advisory (2887505), which addressed a vulnerability that could allow remote code execution.
So caught up so far?
Today Microsoft appears to have released the update again for some reason and it has not only shown up in the Microsoft Download Center but also in Windows Update now.
The three updates can be downloaded through Windows Update on your device or you can access the appropriate version at the Download Center.
Here are the links to them:
- Update for Internet Explorer 11 for Windows 8.1 (KB2901549)
- Update for Internet Explorer 11 for Windows 8.1 for x64-based systems (KB2901549)
- Update for Internet Explorer 11 for Windows Server 2012 R2 (KB2901549)
If you have automatic updates turned on these should be installed on your system without any intervention on your part.
