RHEL 5 / 6 : xulrunner (RHSA-2012:0143)

medium Nessus Plugin ID 57995

Language:

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.

Solution

Update the affected xulrunner, xulrunner-debuginfo and / or xulrunner-devel packages.
