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
