If you install an update through Microsoft Update, the appropriate cumulative update will be automatically installed together with the security update.
However, if you plan to apply an update manually by downloading it from the Microsoft Download Center, you should be aware that the Lync Server Update Installer on Microsoft Download Center page will automatically install previous Cumulative Updates (CU) for all Lync Servers.
