I would surely love to see a step-by-step article on locking down a Mint main edition system to block these threats.
Also, do the Mint developers plan to replace X, as Ubuntu appears to be doing with Mir? Here's a cut from the PC World article:
X.org has security issues going back 20+ years
Late last year, we learned there are a huge list of security vulnerabilities in the X.org graphical server and its libraries. Some of these security holes have been around for more than 20 years. The researcher who discovered these holes said X.org security was a disaster, and “it’s worse than it looks.”
This week, many of these security vulnerabilities were made public knowledge. Your Linux distribution should be rolling out security updates for your X.org server and proprietary NVIDIA driver shortly, if it hasn’t already. But, even after these patches, X.org security still doesn’t inspire much confidence.
X.org is such a big problem because it’s based on the X11 architecture, which originated 30 years ago. Thankfully, new graphical server technologies like Wayland and Ubuntu’s Mir are about to take X.org’s place.
