I have no details, but am investigating.
I know there are some Bluetooth 0days floating around for various platforms, but this one wasn’t on my list.
This was presented at a conference in Europe. A copy of the presentation is here. In the presentation it looks like the flaw is patched, but I’m checking with the author to find out for sure.
Right now nothing to panic about, but I do stand by my advice to start limiting wireless use in public areas. I still use my wireless, but I leave it off when I don’t need an active connection.
Which you probably already do for battery life, right?
