So I recently moved to a new job where we are running full blown enterprise Redhat Linux. RHEL 6 to be exact. Being a big Redhat fan, and Certified Redhat Engineer I was pretty excited to play with the real thing and kick CentOS to the curb for a while. I was not dissapointed as my first couple of weeks on the job turned into a crash course in Satellite Server and the Redhat Linux Life Cycle.
Specifically I needed to figure out how to fix a couple of security vulnerabilites in 6.3 which patches that were only part of 6.4, and could not be found in the official RHEL 6.3 repos. Side note however, I was not allowed to update the server completely to RHEL 6.4.
Thankfully I found a few simple commands that helped me hack together this Frankenstein.
#yum –security check-update
The command above will list any and all security updates that are availbile, then you can run the command below to install them
#yum update –security
Another cool command is shown below.
This command gives you the CLA code for each fix which you can then use to obtain more information on the fix
#yum info-security CLA-2012:1353
