It’s ready to download June 2014 CUs for SharePoint 2013. Please as in April 2014 Exe and cabs are split so you will need to download several files
SharePoint 2013 (Build 15.0.4623.1001)
- SharePoint Foundation 2013 (MSF) June 2014 CU – KB 2881063
- SharePoint Server 2013 (MSS) June 2014 CU – KB 2881061
- Office Web Apps Server 2013 (MSS) June 2014 CU – KB 2881051
After installing the updated you should run the SharePoint Config Wizard in every server of the farm.
If SPS 2013 installed you must only install the SPS 2013 CU because it includes the Foundation one.
