Synopsis

The remote Red Hat host is missing a security update for firefox.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2010:0556 advisory.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

An invalid free flaw was found in Firefox's plugin handler. Malicious web content could result in an invalid memory pointer being freed, causing Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running the Firefox application. (CVE-2010-2755)

All Firefox users should upgrade to these updated packages, which contain a backported patch that corrects this issue. After installing the update, Firefox must be restarted for the changes to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL firefox package based on the guidance in RHSA-2010:0556.
