Ubuntu Security Notice USN-2475-1
January 15, 2015
gtk+3.0 update
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
GTK+ improperly handled the menu key, possibly allowing lock screen bypass.
Software Description:
- gtk+3.0: GTK+ graphical user interface library
Details:
Clemens Fries discovered that GTK+ allowed bypassing certain screen locks
by using the menu key. An attacker with physical access could possibly use
this flaw to gain access to a locked session.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 LTS:
libgtk-3-0 3.10.8-0ubuntu1.4
After a standard system update you need to restart your session to make
all the necessary changes.
