The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2010:0782 :
Updated firefox packages that fix several security issues are now
available for Red Hat Enterprise Linux 4 and 5.
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. Network Security Services
(NSS) is a set of libraries designed to support the development of
security-enabled client and server applications.
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-2010-3175, CVE-2010-3176, CVE-2010-3179,
A flaw was found in the way the Gopher parser in Firefox converted
text into HTML. A malformed file name on a Gopher server could, when
executed in the context of the Gopher domain. (CVE-2010-3177)
A same-origin policy bypass flaw was found in Firefox. An attacker
could create a malicious web page that, when viewed by a victim, could
steal private data from a different website the victim has loaded with
A flaw was found in the script that launches Firefox. The
LD_LIBRARY_PATH variable was appending a '.' character, which could
allow a local attacker to execute arbitrary code with the privileges
of a different user running Firefox, if that user ran Firefox from
within an attacker-controlled directory. (CVE-2010-3182)
This update also provides NSS version 3.12.8 which is required by the
updated Firefox version, fixing the following security issues :
It was found that the SSL DHE (Diffie-Hellman Ephemeral) mode
implementation for key exchanges in Firefox accepted DHE keys that
were 256 bits in length. This update removes support for 256 bit DHE
keys, as such keys are easily broken using modern hardware.
A flaw was found in the way NSS matched SSL certificates when the
certificates had a Common Name containing a wildcard and a partial IP
address. NSS incorrectly accepted connections to IP addresses that
fell within the SSL certificate's wildcard range as valid SSL
connections, possibly allowing an attacker to conduct a
man-in-the-middle attack. (CVE-2010-3170)
For technical details regarding these flaws, refer to the Mozilla
security advisories for Firefox 3.6.11. 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 3.6.11, which corrects these issues. After
installing the update, Firefox must be restarted for the changes to
