Marsh Ray of PhoneFactor has discovered a flaw in the TLS/SSL protocol 
related to the handling of the session renegotiations.  In certain 
circumstances this flaw could be used in MITM attacks, allowing an 
attacker to inject attacker-chosen plain text prefix into a secure session 
of the victim.

Thanks, Mark
