Yum – List Only Security Updates

I’ve been really MS inundated at work lately with exchange 2010, UAG 2010, and Communicator deployments/migrations. So to balance my life a bit I better do a quick post of a linux hack 🙂 Here is a quick one I tacked together about 6 months ago. This will generate a detailed report of all the security updates you are missing with a description of what the update will fix. You will need the yum-security package installed for this to work.

yum list-security | awk 'NR!=1 {print $1}' | sed '/list-security/d' | xargs yum info-security > security_report.txt
