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