3. Description:

Mozilla Thunderbird is a standalone mail and newsgroup client.

A flaw was found in the processing of malformed JavaScript 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-2008-1380)

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

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

4. Solution:
