Synopsis:    Moderate: qt4 security update
Issue Date:  2011-09-21
CVE Numbers: CVE-2007-0242
              CVE-2011-3193


Qt 4 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 flaw in the way Qt 4 expanded certain UTF-8 characters could be used 
to prevent a Qt 4 based application from properly sanitizing user input.
Depending on the application, this could allow an attacker to perform
directory traversal, or for web applications, a cross-site scripting 
(XSS) attack. (CVE-2007-0242)

A buffer overflow flaw was found in the harfbuzz module in Qt 4. If a 
user loaded a specially-crafted font file with an application linked 
against Qt 4, it could cause the application to crash or, possibly, 
execute arbitrary code with the privileges of the user running the 
application. (CVE-2011-3193)

Users of Qt 4 should upgrade to these updated packages, which contain
backported patches to correct these issues. All running applications 
linked against Qt 4 libraries must be restarted for this update to take 
effect.
