Debian and Ubuntu have the updated packages available already so you can upgrade those.
Once the packages are updated and available for your distro, update your box.
For CentOS, Red Hat, Fedora, Scientific Linux,: $ yum clean all && yum update
For Debian, Ubuntu and derivatives: $ apt-get clean && apt-get update && apt-get upgrade
After update, done a reboot to your server or vps.
