Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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,
CVE-2013-0783)

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)

Note that due to a Kerberos credentials change, the following
configuration steps 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.

After installing the update, Firefox must be restarted for the changes
to take effect.
