Mozilla Thunderbird < 3.0.10 Buffer Overflow

High Nessus Plugin ID 50384


The remote Windows host contains a mail client that is affected by a buffer overflow vulnerability.


The installed version of Thunderbird is earlier than 3.0.10. Such versions are potentially affected by a heap-based buffer overflow vulnerability.

The combination of DOM insertions and the handling of the JavaScript function 'document.write()' exposes an error that can lead to a heap-based buffer overflow.

Note that reading email does not expose this vulnerability, however the vulnerability can be triggered when viewing RSS feeds while JavaScript or third-party plugins providing browser-like functionality are enabled.

Also, note that there have been reports that this issue is being actively exploited in the wild.


Upgrade to Thunderbird 3.0.10 or later.
