Comment 5 for bug 317944

Strange that every single device has lost its world ownership permission; the only ones I note with it left are:

23204068 0 srw-rw-rw- 1 root root 0 Jan 16 15:12 /dev/log
  5862 0 crw-rw-rw- 1 root root Oct 10 16:25 /dev/null
  1305 0 crw-rw-rw- 1 root root Oct 21 10:25 /dev/urandom

Do you think something might have actually done "find | chmod" and escaped and run across /dev for some reason?

Do you happen to have system logs from the upgrade time, there may be messages that give us a clue what happened.
