RHEL 4 / 5 / 6 : firefox (RHSA-2011:1242)

This script is Copyright (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Updated firefox packages that fix one security issue are now available
for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having
important security impact.

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

It was found that a Certificate Authority (CA) issued a fraudulent
HTTPS certificate. This update renders any HTTPS certificates signed
by that CA as untrusted, except for a select few. The now untrusted
certificates that were issued before July 1, 2011 can be manually
re-enabled and used again at your own risk in Firefox
however,
affected certificates issued after this date cannot be re-enabled or
used. (BZ#734316)

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