RHBA-2012:0282 - Bug Fix Advisory

Topic

Updated gdm packages that fix three bugs are now available for Red Hat
Enterprise Linux 5.

Description

The GNOME Display Manager (GDM) is a highly configurable reimplementation of
XDM, the X Display Manager. GDM allows you to log into your system with the X
Window System running and supports running several different X sessions on your
local machine at the same time.

This update fixes the following bugs:

• Previously, the gdmsetup utility did not automatically add users to the user

whitelist file /etc/gdm/custom.conf, although these users were configured for
automatic login. With this update, the problem has been fixed and users are now
automatically added to the whitelist file, as expected. (BZ#217417)

• Previously, the GDM GUI was not properly resized when the failed

authentication message was displayed for the user. As a result, the failed
authentication message was not displayed correctly. With this update, the
problem has been fixed so that the GUI is resized properly and the message is
displayed as expected. (BZ#575771)

• When shutting down the X Window System, the gdm-rh-security-token-helper

program could have terminated unexpectedly with a segmentation fault under
certain circumstances. With this update, the problem has been fixed, and
gdm-rh-security-token-helper works as expected. (BZ#658506)

All users of GDM are advised to upgrade to these updated packages, which fix
these bugs.
