Synopsis: Moderate: qt security update
Issue Date: 2011-09-21
CVE Numbers: CVE-2011-3193
 CVE-2011-3194

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.
