The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2012:0084 :
Updated SeaMonkey packages that fix two 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, e-mail and newsgroup client,
IRC chat client, and HTML editor.
A flaw was 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-2012-0442)
The same-origin policy in SeaMonkey treated http://example.com and
http://[example.com] as interchangeable. A malicious script could
possibly use this flaw to gain access to sensitive information (such
as a client's IP and user e-mail address, or httpOnly cookies) that
may be included in HTTP proxy error replies, generated in response to
invalid URLs using square brackets. (CVE-2011-3670)
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.
