[CentOS] Centos security update

Hi,

I was using CentOS 7 and when I ran some custom commercial security scan on
my machine, I found about 122 vulnerabilities.

Can you help me on how to get security upgrades on top of my existing
CentOS?

# cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)

Thanks for the help.
