[mininet-discuss] NTP vulnerabilities in Ubuntu (and Mininet VMs)

Recently a number of high-profile and serious security vulnerabilities have been discovered in ntp on Ubuntu and other operating systems:

If you're running a Mininet VM (or any other Ubuntu machine) and haven't updated or removed ntp, I would recommend either updating:

$ sudo apt-get update
$ sudo apt-get upgrade ntp ntpdate

or simply removing anything ntp-like:

$ sudo apt-get remove ntp ntpdate

I've also updated the 2.2.0 VM images.
