Extracted from the original article.

The product group released the delayed August 2011 Cumulative Update for the SharePoint 2010 product family.

Be aware that the August Cumulative Update for SharePoint 2010 is a Post-SP1 hotfix. That means that you should ensure that SP1 is installed before the August CU.

The KB articles for August CU (2007 and 2010) can be found at the following locations:

KB 2553022 - WSS 3.0

KB 2553020 - MOSS 2007

KB 2553050 - SharePoint Foundation 2010

KB 2553048 - SharePoint Server 2010

KB 2553049 - SharePoint Server 2010 with Project Server
As you see there is a separate Full Server Package for SharePoint Server 2010 with Project Server which simplifies patching of this common installation.

The Full Server Packages for August 2011 CU are available through the following links:

After installing the fixes you need to run the SharePoint 2010 Products Configuration Wizard on each machine in the farm.

Be aware that the SharePoint Server 2010 CU contains the SharePoint Foundation CU. And the SharePoint Server 2010 with Project Server CU contains Project Server CU, SharePoint Server CU and SharePoint Foundation CU.
