The remote host is missing an update for the 'firefox'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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-2013-0775, CVE-2013-0780, CVE-2013-0782,

It was found that, after canceling a proxy server's authentication
prompt, the address bar continued to show the requested site's address. An
attacker could use this flaw to conduct phishing attacks by tricking a
user into believing they are viewing a trusted site. (CVE-2013-0776)

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Nils, Abhishek Arya, Olli Pettay, Christoph Diehl,
Gary Kwong, Jesse Ruderman, Andrew McCreight, Joe Drew, Wayne Mery, and
Michal Zalewski as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 17.0.3 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.

Note that due to a Kerberos credentials change, the configuration
steps in the linked references may be required when using Firefox 17.0.3 ESR
with the Enterprise Identity Management (IPA) web interface.

Important: Firefox 17 is not completely backwards-compatible with all
Mozilla add-ons and Firefox plug-ins that worked with Firefox 10.0.
Firefox 17 checks compatibility on first-launch, and, depending on the
individual configuration and the installed add-ons and plug-ins, may
disable said Add-ons and plug-ins, or attempt to check for updates and
upgrade them. Add-ons and plug-ins may have to be manually updated.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 17.0.3 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.

Affected Software/OS:
firefox on Red Hat Enterprise Linux (v. 5 server),
Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)
