Synopsis:          Low: gtk2 security and bug fix update
Issue Date:        2013-01-08
CVE Numbers:       CVE-2012-2370
--

An integer overflow flaw was found in the X BitMap (XBM) image file 
loader in
GTK+. A remote attacker could provide a specially-crafted XBM image file 
that,
when opened in an application linked against GTK+ (such as Nautilus), would
cause the application to crash. (CVE-2012-2370)

This update also fixes the following bugs:

* Due to a bug in the Input Method GTK+ module, the usage of the 
Taiwanese Big5
(zh_TW.Big-5) locale led to the unexpected termination of certain 
applications,
such as the GDM greeter. The bug has been fixed, and the Taiwanese locale no
longer causes applications to terminate unexpectedly.

* When a file was initially selected after the GTK+ file chooser dialog was
opened and the Location field was visible, pressing the Enter key did 
not open
the file. With this update, the initially selected file is opened 
regardless of
the visibility of the Location field.

* When a file was initially selected after the GTK+ file chooser dialog was
opened and the Location field was visible, pressing the Enter key did not
change into the directory. With this update, the dialog changes into the
initially selected directory regardless of the visibility of the Location
field.

* Previously, the GTK Print dialog did not reflect the user-defined printer
preferences stored in the ~/.cups/lpoptions file, such as those set in the
Default Printer preferences panel. Consequently, the first device in the
printer list was always set as a default printer. With this update, the
underlying source code has been enhanced to parse the option file. As a 
result,
the default values in the print dialog are set to those previously 
specified by
the user.

* The GTK+ file chooser did not properly handle saving of nameless files.
Consequently, attempting to save a file without specifying a file name 
caused
GTK+ to become unresponsive. With this update, an explicit test for this
condition has been added into the underlying source code. As a result, 
GTK+ no
longer hangs in the described scenario.

* When using certain graphics tablets, the GTK+ library incorrectly 
translated
the input coordinates. Consequently, an offset occurred between the 
position of
the pen and the content drawn on the screen. This issue was limited to the
following configuration: a Wacom tablet with input coordinates bound to a
single monitor in a dual head configuration, drawing with a pen with the
pressure sensitivity option enabled. With this update, the coordinate
translation method has been changed, and the offset is no longer present 
in the
described configuration.

* Previously, performing drag and drop operations on tabs in 
applications using
the GtkNotebook widget could lead to releasing the same resource twice.
Eventually, this behavior caused the applications to terminate with a
segmentation fault. This bug has been fixed, and the applications using
GtkNotebook no longer terminate in the aforementioned scenario.

All users of GTK+ are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
