The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2012:1350 :
Updated firefox packages that fix several security issues and one bug
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-2012-3982, CVE-2012-3988, CVE-2012-3990,
CVE-2012-3995, CVE-2012-4179, CVE-2012-4180, CVE-2012-4181,
CVE-2012-4182, CVE-2012-4183, CVE-2012-4185, CVE-2012-4186,
Two flaws in Firefox could allow a malicious website to bypass
intended restrictions, possibly leading to information disclosure, or
Firefox executing arbitrary code. Note that the information disclosure
issue could possibly be combined with other flaws to achieve arbitrary
code execution. (CVE-2012-3986, CVE-2012-3991)
Multiple flaws were found in the location object implementation in
Firefox. Malicious content could be used to perform cross-site
scripting attacks, script injection, or spoofing attacks.
(CVE-2012-1956, CVE-2012-3992, CVE-2012-3994)
Two flaws were found in the way Chrome Object Wrappers were
implemented. Malicious content could be used to perform cross-site
scripting attacks or cause Firefox to execute arbitrary code.
For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 10.0.8 ESR. You can find a link to the
Mozilla advisories in the References section of this erratum.

storage.nfs_filesystem, that can be used to resolve this issue.
