Synopsis
========
An authentication error in GDM could allow users to gain elevated
privileges.
Background
==========
GDM is the GNOME display manager.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 gnome-base/gdm < 2.8.0.8 >= 2.8.0.8
Description
===========
GDM allows a normal user to access the configuration manager.
Impact
======
When the "face browser" in GDM is enabled, a normal user can use the
"configure login manager" with his/her own password instead of the root
password, and thus gain additional privileges.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GDM users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-base/gdm-2.8.0.8"
