Many of you by now will be aware of the ditryc0w exploit, if you follow linux news at all. It's an exploit that allows an unpriveledged program to modify a file it doesn't have access to. So, I built the exploit testing code on my Pandora and ran it. It took a while, but it did modify the file which I'd chmodded to make read only (https://raw.githubusercontent.com/dirtycow/dirtycow.github.io/master/dirtyc0w.c). Big-time erk! So, there's unlikely to be a problem on the Pandora just yet, it's not remomotely exploitable, and nobody would have tried this technique before it was published, *and* we can mostly trust new software from users with a reputation, but it does mean that if someone we don't know now produces a new PND it might contain this exploit, and modify system software unbeknown to us. Anyone else fancy testing this? When I tried it, it missed off the last character of my changed contents, but that may be because I used quoted parameters. It takes a little while to run - I forgot about it but it finished atfer 2 hours, and it took 20 minutes or so on my laptop (but I'd already patched that to be protected). Do we need a patch for this? Can we expect one?
