3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

A race condition flaw was found in the way Thunderbird handled Document
Object Model (DOM) element properties. An HTML mail message containing
malicious content could cause Thunderbird to crash or, potentially, execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2010-3765)

Note: JavaScript support is disabled by default in Thunderbird. The
CVE-2010-3765 issue is not exploitable unless JavaScript is enabled.

All Thunderbird users should upgrade to this updated package, which
resolves this issue. All running instances of Thunderbird must be restarted
for the update to take effect.
