CVE-2009-2697 gdm not built with tcp_wrappers
A flaw was found in the way the gdm package was built. The gdm package
was missing TCP wrappers support, which could result in an
administrator believing they had access restrictions enabled when they
did not. (CVE-2009-2697)
This update also fixes the following bugs :
- the GDM Reference Manual is now included with the gdm
packages. The gdm-docs package installs this document in
HTML format in '/usr/share/doc/'. (BZ#196054)
- GDM appeared in English on systems using Telugu (te_IN).
With this update, GDM has been localized in te_IN.
- the Ctrl+Alt+Backspace sequence resets the X server when
in runlevel 5. In previous releases, however, repeated
use of this sequence prevented GDM from starting the X
server as part of the reset process. This was because
GDM sometimes did not notice the X server shutdown
properly and would subsequently fail to complete the
reset process. This update contains an added check to
explicitly notify GDM whenever the X server is
terminated, ensuring that resets are executed reliably.
- the 'gdm' user is now part of the 'audio' group by
default. This enables audio support at the login screen.
- the gui/modules/dwellmouselistener.c source code
contained incorrect XInput code that prevented tablet
devices from working properly. This update removes the
errant code, ensuring that tablet devices work as
- a bug in the XOpenDevice() function prevented the X
server from starting whenever a device defined in
'/etc/X11/xorg.conf' was not actually plugged in. This
update wraps XOpenDevice() in the gdk_error_trap_pop()
and gdk_error_trap_push() functions, which resolves this
bug. This ensures that the X server can start properly
even when devices defined in '/etc/X11/xorg.conf' are
not plugged in. (BZ#474588)
GDM must be restarted for this update to take effect. Rebooting
achieves this, but changing the runlevel from 5 to 3 and back to 5
also restarts GDM.
Note: setup needed to be updated for dependencies.
