Updated gtk2 packages that fix one bug are now available for Red Hat Enterprise Linux 5.
GIMP Toolkit (GTK+) is a multi-platform toolkit for creating graphical user interfaces.

Bug Fix

BZ#830901
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 a segmentation fault. This bug has been fixed, and the applications using GtkNotebook no longer crash in the described scenario.
All users of GTK+ are advised to upgrade to these updated packages, which fix this bug.
Updated gtk2 packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) associated with each description below.

Security Fix

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.

Bug Fixes

BZ#487630
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.
BZ#518483
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.
BZ#523657
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.
BZ#603809
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.
BZ#702342
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.
BZ#743658
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.
BZ#830901
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.
