thunderbird security update

CentOS Errata and Security Advisory CESA-2008:0209

Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of some malformed HTML mail
content. An HTML mail message containing such malicious content could cause
Thunderbird to crash or, potentially, execute arbitrary code as the user
running Thunderbird. (CVE-2008-1233, CVE-2008-1235, CVE-2008-1236,
CVE-2008-1237)

Several flaws were found in the display of malformed web content. An HTML
mail message containing specially-crafted content could, potentially, trick
a user into surrendering sensitive information. (CVE-2008-1234,
CVE-2008-1238, CVE-2008-1241)

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

All Thunderbird users should upgrade to these updated packages, which
contain backported patches to resolve these issues.
