RHBA-2010:0944 - Bug Fix Advisory

Topic

An updated gnome-screensaver package that fixes a bug is now available for Red
Hat Enterprise Linux 5.

Description

The gnome-screensaver package contains the GNOME project's official screen saver
program. It is designed for improved integration with a GNOME desktop, including
themeability, language support, and Human Interface Guidelines (HIG) compliance.
It also provides screen-locking and fast user-switching from a locked screen.

A recent bug fix introduced in RHBA-2010:0826 uncovered a latent bug in
gnome-screensaver's PAM message handling. This update fixes the following
manifestations of that bug:

• An attempt to unlock a locked screen using the smart card authentication

failed. With this update, this error no longer occurs, and unlocking a screen
with the smart card authentication no works as expected. (BZ#656924)

• When using cached credentials with the System Security Services Daemon (SSSD),

an attempt to unlock a locked screen in the "offline mode" could fail. With this
update, this error has been fixed, and such attempt no longer fails. (BZ#657044)

Users of gnome-screensaver should upgrade to this updated package, which
resolves these issues.
