# CVE-2014-1295 (Apple's Secure Transport and Triple Handshake Attack)

Apple is releasing some updates today. They have not published the bulletins yet, but they are available here: https://gist.github.com/FredericJacobs/11189734.

In the writeup for CVE-2014-1295:

Security - Secure Transport
...

Impact: An attacker with a privileged network position may capture
data or change the operations performed in sessions protected by SSL

Description: In a 'triple handshake' attack, it was possible for an
attacker to establish two connections which had the same encryption
keys and handshake, insert the attacker's data in one connection, and
renegotiate so that the connections may be forwarded to each other.
To prevent attacks based on this scenario, Secure Transport was
changed so that, by default, a renegotiation must present the same
server certificate as was presented in the original connection.


How is it possible to run two instances of a protocol and get the same parameters? Wouldn't nonces specifically neutralize this attack?

(And sorry about the crummy tagging).
