I know it's not what linux admins are used to but remember to reboot your 
machines after you ever install a new kernel as part of a yum update.  This is 
the only way of booting from that new kernel and getting the patches/protection 
required.

I recently took ownership of a box the other day, the previous sysadmin had done 
a great job keeping it patched however as he hadn't been rebooting for kernel 
updates.  The kernel he was running was VERY old and had a number of security 
holes in it which had anyone gotten in would have easily elevated their 
permissions to root.  I know it's a pain but a simple reboot fixed this.
