Synopsis :

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

Description :

Updated xulrunner packages that fix one security issue are now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
critical security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

XULRunner provides the XUL Runtime environment for applications using
the Gecko layout engine.

A heap-based buffer overflow flaw was found in the way XULRunner
handled PNG (Portable Network Graphics) images. A web page containing
a malicious PNG image could cause an application linked against
XULRunner (such as Firefox) to crash or, potentially, execute
arbitrary code with the privileges of the user running the
application. (CVE-2011-3026)

All XULRunner users should upgrade to these updated packages, which
correct this issue. After installing the update, applications using
XULRunner must be restarted for the changes to take effect.
