3. Description:

Qt is a software toolkit that simplifies the task of writing and
maintaining GUI (Graphical User Interface) applications for the X Window
System. HarfBuzz is an OpenType text shaping engine.

A buffer overflow flaw was found in the harfbuzz module in Qt. If a user
loaded a specially-crafted font file with an application linked against Qt,
it could cause the application to crash or, possibly, execute arbitrary
code with the privileges of the user running the application.
(CVE-2011-3193)

A buffer overflow flaw was found in the way Qt handled certain gray-scale
image files. If a user loaded a specially-crafted gray-scale image file
with an application linked against Qt, it could cause the application to
crash or, possibly, execute arbitrary code with the privileges of the user
running the application. (CVE-2011-3194)

Users of Qt should upgrade to these updated packages, which contain
backported patches to correct these issues. All running applications linked
against Qt libraries must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

733118 - CVE-2011-3193 qt/harfbuzz buffer overflow
733119 - CVE-2011-3194 qt buffer overflow in greyscale images
