Updated firefox packages that fix several security issues 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. 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.

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

Several flaws were found in the processing of malformed web content. A
web page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox. (CVE-2013-1718, CVE-2013-1722, CVE-2013-1725, CVE-2013-1730,
CVE-2013-1732, CVE-2013-1735, CVE-2013-1736)

A flaw was found in the way Firefox handled certain DOM JavaScript objects.
An attacker could use this flaw to make JavaScript client or add-on code
make incorrect, security sensitive decisions. (CVE-2013-1737)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges André Bargull, Scoobidiver, Bobby Holley,
Reuben Morais, Abhishek Arya, Ms2ger, Sachin Shinde, Aki Helin, Nils, and
Boris Zbarsky as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 17.0.9 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 17.0.9 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
