Hi

It's ready to download June 2013 CUs for SharePoint 2013

SharePoint 2013 (Build 15.0.4517.1005) 

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.
