Original advisory details:

 Marsh Ray and Steve Dispensa discovered a flaw in the TLS and SSLv3
 protocols. If an attacker could perform a machine-in-the-middle attack at the
 start of a TLS connection, the attacker could inject arbitrary content at
 the beginning of the user's session. This update adds support for the new
 new renegotiation extension and will use it when the server supports it.");
