> I wanted to dispute the existence of CVE-2009-0125 (libnasl misusing the 
> return value of DSA_do_verify()) : while we do misuse this function (this is 
> a bug), it has absolutely no security ramification.
> To give you some context, the function DSA_do_verify() is called by the nasl 
> function  dsa_do_verify() which is used when Nessus attempts to log into a 
> remote SSH server.
> If an attacker were to control a rogue SSH server, then he would be better 
> off submitting a perfectly valid signature instead of a malformed one, and we 
> would log into it anyways. Hence, there is absolutely no security risk 
> associated with the misuse of this function.
