Bug#729683: gnome-orca: orca reads password text entries aloud

Package: gnome-orca
Version: 3.4.2-2
Severity: normal

Hi Orca folks--

It looks like the gnome screen-reader reads back every key pressed
into a password text entry field.  If the computer in question has
public audio enabled, this effectively reads the user's password aloud
to anyone else in the room.

Most egregiously, this happens in the gdm3 login greeter during
password entry.  This is particularly bad because anyone (without
authentication) can enable the screen reader for the gdm3 greeter via
the accessibility menu (see http://bugs.debian.org/689559), and leave
it that way for the next person who logs in.

I note that sometimes (i haven't been able to track down what the
difference is), gnome does read each character of the password text as
"asterisk".  that's clumsy, but it's way better from a security point
of view than the behavior i'm currently seeing (hearing).

To reproduce the problem, i launched a kvm guest with a minimal wheezy
install, then installed (without Recommends):

 xserver-xorg orca gnome-orca pulseaudio pulseaudio-module-x11 xbrlapi
 gnome-mag libbonobo2-bin speech-dispatcher-festival festvox-kallpc16k
 sox sound-icons openbox at-spi2-core desktop-base

and then, finally:

 apt-get install gdm3

It seems likely that an even more minimalist config could reproduce
the problem too.
