[SAC] [Hosting] PSA: Please update polkit on all Linux systems ASAP

[Lance Albertson]

In case you missed the announcement yesterday [1][2], there was a really
nasty vulnerability in polkit released. All major distributions should have
fixes for it now so I urge everyone to update their systems ASAP.

We upgraded all of our systems yesterday without any issues. I also
recommend everyone to enable automatic upgrades on your systems if you're
able to.
