RHEL 5 : qt4 (RHSA-2011:1324)

High Nessus Plugin ID 56251


The remote Red Hat host is missing one or more security updates.


Updated qt4 packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.


Update the affected packages.
