This is the first Exchange 2013 update that resolves only security issues.  As previously mentioned with the new servicing model security updates will be release separately from the other Cumulative Updates servicing updates.

In order to install this security update, you must have installed the updated build of Exchange 2013 RTM CU2 which is described here.  This is the 712.24 build of Exchange.

Please test before installing this update into production!  This is not a surprise, as every update to the messaging infrastructure should be carefully tested and reviewed prior to installing in production.
