Synopsis :

The remote Red Hat host is missing a security update.

Description :

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-2008-5500, CVE-2008-5501,
CVE-2008-5502, CVE-2008-5511, CVE-2008-5512, CVE-2008-5513)

Several flaws were found in the way malformed content was processed.
An HTML mail message containing specially crafted content could
potentially trick a Thunderbird user into surrendering sensitive
information. (CVE-2008-5503, CVE-2008-5506, CVE-2008-5507)

Note: JavaScript support is disabled by default in Thunderbird
the
above issues are not exploitable unless JavaScript is enabled.

A flaw was found in the way malformed URLs were processed by
Thunderbird. This flaw could prevent various URL sanitization
mechanisms from properly parsing a malicious URL. (CVE-2008-5508)

All Thunderbird users should upgrade to these updated packages, which
resolve these issues. All running instances of Thunderbird must be
restarted for the update to take effect.
