The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2011:0313 :
Updated SeaMonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 4.
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.
SeaMonkey is an open source web browser, email and newsgroup client,
IRC chat client, and HTML editor.
A flaw was found in the way SeaMonkey handled dialog boxes. An
attacker could use this flaw to create a malicious web page that would
present a blank dialog box that has non-functioning buttons. If a user
closes the dialog box window, it could unexpectedly grant the
malicious web page elevated privileges. (CVE-2011-0051)
Several flaws were found in the processing of malformed web content. A
web page containing malicious content could cause SeaMonkey to crash
or, potentially, execute arbitrary code with the privileges of the
user running SeaMonkey. (CVE-2011-0053)
A flaw was found in the way SeaMonkey handled plug-ins that perform
HTTP requests. If a plug-in performed an HTTP request, and the server
sent a 307 redirect response, the plug-in was not notified, and the
HTTP request was forwarded. The forwarded request could contain custom
headers, which could result in a Cross Site Request Forgery attack.
All SeaMonkey users should upgrade to these updated packages, which
correct these issues. After installing the update, SeaMonkey must be
restarted for the changes to take effect.
