Due to high work load, I’m again a bit delayed. Please apologize… 
As usual, here is the August 2013 CU release. please find all info below.
NOTE!
In order to install future updates, the March 2013 PU will be mandatory! So you must install these updates on RTM Farms before you can install subsequent updates in the future! – Click here for Download March PU 2013!
For servers that include search components, you have to follow specific steps to ensure that you install the PU correctly.
Please find here important advise on how to do that correctly:
How to install update packages on a SharePoint farm where search component and high availability search topologies are enabled
As usual, you need to run the SharePoint 2013 Products Configuration Wizard on each machine in the farm after installing the packages.
The SharePoint Server pack contains the Foundation packs, so you basically only need to install one Package.
The project Server Packs are containing both, so if you install this one, no need for the other two to install additionally.

Common Question: What is the difference between a PU, a CU and a COD?
SharePoint mysteries and more... 
Hi Sagar,
AFAIK, not for Sharepoint August 13 CU's. There were some for the Outlook Client part which are fixed meanhwile but will not affect SharePoint Servers.
So you should be almost ok with the August 13 CU's.
But as always recommended:
1. Do only install the CU if you are far behind the patch line or ahving the described issues to be fixed!
2. Make a full backup of your farm and maybe test it Prior to deploy in production!
There is always a risk for issues post the CU install. Even if there is None reported it may happen just on your Environment due to circumstances that were neither tested nor discovered yet!
There is never a full bullet proof warranty with any patch or update you will install.
HtH, cheers, Steve
