Details:

12:48 <neal> I have a nice new attack.
12:49 <neal> chroot /chroot
12:49 <neal> set an active translator on foo
12:49 <neal> cause a program which is not in the chroot to use foo
12:50 <neal> with a path resembling: "/chroot/foo/../../.."
12:50 <neal> if the program uses open, it will open "/chroot"
12:50 <neal> and *NOT* /
12:50 <neal> the reason?
12:51 <neal> when the active translator on /chroot/foo returns the retry
capability on /chroot/foo, the capability is rooted at /chroot
12:52 <neal> transitively due to the file_reparent that chroot does
12:52 <neal> that's a design bug
12:54 <neal> abeaumont: I mean, it's not a bug which can be fixed
12:54 <neal> abeaumont: I means getting rid of .. resolution in translators
