In about an hour, I have the distinct honor to address a room full of federal sector security researchers and scientists at the US Department of Energy's Oak Ridge National Labs, within the Cyber and Information Security Research Conference.
I'm delighted to share with you the slide deck I have prepared for this presentation. You can download a PDF here.
To a great extent, I have simply reformatted the excellent Ubuntu Security Features wiki page our esteemed Ubuntu Security Team maintains, into a format by which I can deliver as a presentation.
Hopefully you'll learn something! I certainly did, as I researched and built this presentation ;-)
On a related security note, it's probably worth mentioning that Canonical's IS team have updated all SSL services with patched OpenSSL from the Ubuntu security archive, and have restarted all relevant services (using Landscape, for the win), against the Heartbleed vulnerability. I will release an updated pollinate package in a few minutes, to ship the new public key for entropy.ubuntu.com.
Today, I decided to set my X230 back to UEFI-only boot, after having changed that for a bios upgrade recently (to fix a resume bug). I then choose to save the settings and received several error messages telling me that the system ran out of resources (probably storage space for UEFI variables).
I rebooted my machine, and saw no logo appearing. Just something like an underscore on a text console. The system appears to boot normally otherwise, and once the i915 module is loaded (and we’re switching away from UEFI’s Graphical Output Protocol [GOP]) the screen works correctly.
So it seems the GOP broke.
What should I do next?

When it comes to Testing Ubuntu GNOME, we need to make sure everything is working as expected without any problem.
That said, we would like to invite you to help Ubuntu GNOME with Upgrade Testing.
How to help Ubuntu GNOME with Upgrade Testing?
The idea is very simple. We need to upgrade Ubuntu GNOME 13.10 to Ubuntu GNOME Trusty Tahr and test the upgrade process.
If you have Ubuntu GNOME 13.10 installed already, we would really appreciate your help in this regard.
If Ubuntu GNOME 13.10 is not installed, then kindly install it and do the upgrade. Installing Ubuntu GNOME from LiveUSB should not take more than 10 minutes.
How to do an upgrade from 13.10 to Trusty Tahr?
Before we get into this, kindly have a read at Upgrades Documentation.
Whether you’re helping Ubuntu GNOME Team with Testing or you’re a fan of running unstable releases on your machine, kindly make sure to backup your important files before anything else.
To upgrade Ubuntu GNOME 13.10 Stable to Ubuntu GNOME Trusty Tahr Development Release, kindly have a read at Upgrading to Development Releases.
Share your Testing Results
Please make sure to share your Testing Results with Ubuntu GNOME QA Team. The more feedback in this regard, the better.
Let’s make sure that our very first LTS Release of Ubuntu GNOME is solid as rock.
Thank you for helping, supporting and testing Ubuntu GNOME!
As always, for more information about testing, please see Ubuntu GNOME Testing Wiki Page.
Should you have any question, please don’t hesitate to Contact Us.
If you are using OpenSSL (or ever did use it with any of your current keypairs in the last 3-4 years), you are probably in a rush to upgrade all your systems and replace all your private keys right now.
If your certificate authority is CACert.org then there is an extra surprise in store for you. CACert.org has changed their hash to SHA-512 recently and some client/server connections silently fail to authenticate with this hash. Any replacement certificates you obtain from CACert.org today are likely to be signed using the new hash. Amongst other things, if you use CACert.org as the CA for a distributed LDAP authentication system, you will find users unable to log in until you upgrade all SSL client code or change all clients to trust an alternative root.
