Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2011:1324 :

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.
