Description:
Aditya K Sood has discovered a weakness in Mozilla Firefox, which can be exploited by malicious people to cause a DoS (Denial of Service).

The weakness is caused due to an error when dispatching "keypress" user interface events with e.g. the HTML root element as target. This may potentially result in use of invalid memory or memory corruption via a specially crafted web page.

Successful exploitation crashes the browser. However, even though code execution has not been proven, it can't be completely ruled out.

The weakness is confirmed in version 3.0.3 for Windows. Version 2.x is not affected.

NOTE: Secunia normally does not classify a browser crash as a vulnerability nor issue an advisory about it. However, the potential impact of this issue may be more severe than currently believed.
