The product group released the December 2013 Cumulative Update for the SharePoint 2010 product family.
Be aware that the December Cumulative Update for SharePoint 2010 is a Post-SP2 hotfix. It is recommended to have SP2 installed before installing the December CU.
The KB articles for December CU are available at the following locations:
  • KB 2849990 - SharePoint Foundation 2010
  • KB 2849971 - SharePoint Server 2010
  • KB 2849972 - 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 December 2013 CU are available through the following links:
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.
That means only one package has to be installed for the SharePoint 2010 product family.
