Avirt 4.2 question

[nicolas brulez <brulez () cartel-securite fr>]

Hello,

I have seen 2 advisories for avirt 4.2 gateway.
Did they patch it without modifying the version ?
I tried the proof of concept exploit and it did nothing but close the 
server.
I wanted to trigger the buffer overflow on the web server too, in order 
to write a proof of concept exploit
but my attempts did nothhing but close the server again.. (something 
like 4000 chars)
I never managed to overwrite my EIP.(or doesn't it crash when you do it ? )
I was wondering if they patched it in a dodgy way ?
Sorry if it is not the good place for such a post ;-)

Best Regards,
