Please use Patch Recommendations to setup and receive Critical Patches
Just an FYI:
The Critical Patch Advisory provides Oracle patch recommendations and vulnerability reports for the latest quarterly Critical Patch Updates (CPUs) for affected Oracle Products. In Enterprise Manager 10.2.0.5 Grid Control, the Deployments page provided admins with the ability to receive Critical Patch Advisory patch recommendations for these quarterly CPU patches. The ability for administrators to setup these recommendations through the "Deployments" page is being deprecated in the next release of Enterprise Manager after 12.1.0.2.
Going forward, Oracle recommends that you upgrade to the latest Enterprise Manager 12c Cloud Control release (EM 12cR2) and use the My Oracle Support ->Patch Recommendation
