Red Hat patching

Hi
I have Redhat 7.3 with KVM on top. when I updated the system I used the only command :
yum --releaseserver=7.3 update

after some scanning for vulnerability, it was obvious there are a lot of missing update

Now lets assume I still want to be tight to 7.3 and not making any compatibility issues with applications running on KVM

are the below commands going to mess things up verses releaseserver=7.3 ?
gpk-update-viewer
yum update or yum update all
yum install vsftpd
yum update bind

how can I patched to the latest without affecting the targeted version 7.3 thanks
