Subject: RE: FreeBSD all versions  FireWire IOCTL kernel integer overflow information disclousure

Is it me, or do you need to be root or a member of the operator group to
be able to perform an IOCTL on /dev/fw*. In FreeBSD at least, /dev/fw*
is only accessible by root (read/write) and members of the operator
group (read-only).

It might be a bug, I'll grant you that, but it's not disclosure to local
users. It's to local users who are part of the operators group. Those
are 1) rare and 2) able to read disk devices directly, which is a little
more useful than being able to read memory.

Please correct me if I'm wrong.

Cheers,

	Rogier
