Hi,
Go to {ColdFusion-Home}/lib/updates (for Server installation) or {ColdFusion-Home}/WEB-INF/cfusion/lib/updates (for Multiserver and J2EE installations) directory. If hf902-00004.jar exists, that confirms, the latest update is applied.
Please refer to http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb13 -10.html for the latest Security Bulletin.

Anit Kumar
