The remote Oracle Linux host is missing a security update.
From Red Hat Security Advisory 2008:0976 :
Updated thunderbird packages that fix several security issues are now
available for Red Hat Enterprise Linux 4 and 5.
This update has been rated as having moderate security impact by the
Red Hat Security Response Team.
Mozilla Thunderbird is a standalone mail and newsgroup client.
Several flaws were found in the processing of malformed HTML mail
content. An HTML mail message containing malicious content could cause
Thunderbird to crash or, potentially, execute arbitrary code as the
user running Thunderbird. (CVE-2008-5014, CVE-2008-5016,
CVE-2008-5017, CVE-2008-5018, CVE-2008-5021)
Several flaws were found in the way malformed HTML mail content was
processed. An HTML mail message containing specially crafted content
could potentially trick a Thunderbird user into surrendering sensitive
information. (CVE-2008-5012, CVE-2008-5022, CVE-2008-5024)
All Thunderbird users should upgrade to these updated packages, which
resolve these issues.
