Title:	RedHat Update for GNOME Shell RHSA-2015:0535-01
Summary:	The remote host is missing an update for the 'GNOME Shell'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'GNOME Shell' package(s) announced via the referenced advisory. Vulnerability Insight: 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 a ...
