Re: Re: New Flaw in Firefox 2.0: DoS and possible remote code execution

When you have a NULL pointer dereference a code execution is also possible, so 
you can't exclude it at all.
For example in this old flaw:
http://securitytracker.com/alerts/2006/Apr/1016001.html
"The browser does not properly process certain combinations of nested OBJECT 
tags. A remote user can create specially crafted HTML that, when loaded by the 
target user, will trigger a NULL pointer dereference and cause the target 
user's browser to crash or execute arbitrary code."
