Please Install the Updated Packages.

Mozilla Thunderbird is a standalone mail and newsgroup client. A cross-site scripting flaw was found in the way Thunderbird handled the jar: URI scheme. It may be possible for a malicious HTML mail message to leverage this flaw, and conduct a cross-site scripting attack against a user running Thunderbird. (CVE-2007-5947) Several flaws were found in the way Thunderbird processed certain malformed HTML mail content. A HTML mail message containing malicious content could cause Thunderbird to crash, or potentially execute arbitrary code as the user running Thunderbird. (CVE-2007-5959) A race condition existed when Thunderbird set the &quot window.location&quot property when displaying HTML mail content. This flaw could allow a HTML mail message to set an arbitrary Referer header, which may lead to a Cross-site Request Forgery (CSRF) attack against websites that rely only on the Referer header for protection. (CVE-2007-5960) All users of thunderbird are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.
