Regarding application of security patches RHEL 5.5

Hi
Is there a direct way to apply a particular security advisory on the system.

Presently we have certain security advisories to be applied which require installation of multiple rpms and their dependencies.

These rpms as listed in the security advisory also mention that they have been outdated by other releases.

So the question is that is downloading and applying all such rpms the only way to confirm to the security advisory or there is some other direct way to get the security advisory updated at the system.
