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.
