    The author's ending words, "My advice to you is to now, not later today, now, update your Linux system as soon as possible. After patching it, you should then reboot the system. I know for Linux it's rarely needed to reboot, but since gethostbyname is called on by so many core processes, such as auditd, dbus-daem, dhclient, init, master, mysqld, rsyslogd, sshd, udevd, and xinetd, you want to make absolutely sure that all your system's running programs are using the patched code." Now, if someone can show a newbie how to exactly make sure my system has been updated and nothing to worry about...

    In something like Ubuntu, open a terminal session.

    Type sudo apt-get update
    Hit Enter, wait for it to complete (requires internet)
    Type sudo apt-get upgrade
    Type Y, hit enter, wait.

    Reboot.

    Keep in mind that if you are on an LTS release of Ubuntu (which are the only affected releases that are still supported) you will not see a version later than 2.15. To determine the specific revision you have, run...

    Code: 
    apt-cache policy libc6
    This will spit out something like...

    Code: 
    libc6:
   Installed: 2.15-0ubuntu10.10
   Candidate: 2.15-0ubuntu10.10
   Version Table: etc...
    http://www.ubuntu.com/usn/usn-2485-1/

    Make sure the ubuntu revision you have installed is at least what is listed in that article, then reboot to make sure you are actually using it.
