SeaMonkey < 2.0.10 Buffer Overflow

high Nessus Plugin ID 50386



The remote Windows host contains a web browser affected by a buffer overflow vulnerability.


The installed version of SeaMonkey is earlier than 2.0.10. 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 there have been reports that this issue is being actively exploited in the wild.


Upgrade to SeaMonkey 2.0.10 or later.
