Issue date: 2015-03-05
CVE Names: CVE-2014-7300
=====================================================================
1. Summary:
Updated gnome-shell, mutter, clutter, and cogl packages that fix one
security issue, several bugs, and add one enhancement are now available for
Red Hat Enterprise Linux 7.

3. Description:
GNOME Shell and the packages it depends upon provide the core user
interface of the Red Hat Enterprise Linux desktop, including functions such
as navigating between windows and launching applications.
It was found that the GNOME shell did not disable the Print Screen key when
the screen was locked. This could allow an attacker with physical access to
a system with a locked screen to crash the screen-locking application by
creating a large amount of screenshots. (CVE-2014-7300)
This update also fixes the following bugs:
* The Timed Login feature, which automatically logs in a specified user
after a specified period of time, stopped working after the first user of
the GUI logged out. This has been fixed, and the specified user is always
logged in if no one else logs in. (BZ#1043571)
* If two monitors were arranged vertically with the secondary monitor above
the primary monitor, it was impossible to move windows onto the secondary
monitor. With this update, windows can be moved through the upper edge of
the first monitor to the secondary monitor. (BZ#1075240)
* If the Gnome Display Manager (GDM) user list was disabled and a user
entered the user name, the password prompt did not appear. Instead, the
user had to enter the user name one more time. The GDM code that contained
this error has been fixed, and users can enter their user names and
passwords as expected. (BZ#1109530)
* Prior to this update, only a small area was available on the GDM login
screen for a custom text banner. As a consequence, when a long banner was
used, it did not fit into the area, and the person reading the banner had
to use scrollbars to view the whole text. With this update, more space is
used for the banner if necessary, which allows the user to read the message
conveniently. (BZ#1110036)
* When the Cancel button was pressed while an LDAP user name and password
was being validated, the GDM code did not handle the situation correctly.
As a consequence, GDM became unresponsive, and it was impossible to return
to the login screen. The affected code has been fixed, and LDAP user
validation can be canceled, allowing another user to log in instead.
(BZ#1137041)
* If the window focus mode in GNOME was set to "mouse" or "sloppy",
navigating through areas of a pop-up menu displayed outside its parent
window caused the window to lose its focus. Consequently, the menu was not
usable. This has been fixed, and the window focus is kept in under this
scenario. (BZ#1149585)
* If user authentication is configured to require a smart card to log in,
user names are obtained from the smart card. The authentication is then
performed by entering the smart card PIN. Prior to this update, the login
screen allowed a user name to be entered if no smart card was inserted, but
due to a bug in the underlying code, the screen became unresponsive. If, on
the other hand, a smart card was used for authentication, the user was
logged in as soon as the authentication was complete. As a consequence, it
was impossible to select a session other than GNOME Classic. Both of these
problems have been fixed. Now, a smart card is required when this type of
authentication is enabled, and any other installed session can be selected
by the user. (BZ#1159385, BZ#1163474)
In addition, this update adds the following enhancement:
* Support for quad-buffer OpenGL stereo visuals has been added. As a
result, OpenGL applications that use quad-buffer stereo can be run and
properly displayed within the GNOME desktop when used with a video driver
and hardware with the necessary capabilities. (BZ#861507, BZ#1108890,
BZ#1108891, BZ#1108893)
All GNOME Shell users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues and add this
enhancement.
