I don't have any, but if anyone here does, here's a heads up, there are exploits in the wild I can see being discussed.
I'm fairly sure most people should receive this update automatically. In any case, I did. The method of exploitation seems fairly remote from being practical, so I'm also not that concerned.
I would be more concerned about network attached cheap IoT stuff from Aliexpress and the likes.
This affects the Philips Hue Hub and not the lights, from what I can tell. And as Michael said it gets updates automatically.
Well, perhaps it will auto-update and perhaps it's rare, but no harm in checking and making sure it's secure.
Attending an IT conference recently, security was a big talking point (of course!) and the number of exploits that would have seemed impractical a couple of years ago, that are around now and being exploited in the wild, are becoming more and more common.
