Hi all,
is it possible to add in

If rfc3261 conformance is desired, TLSv1 must be used. For
compatibility with older clients SSLv23 is a good option.
*Example 1.3. Set |tls_method| parameter*

modparam("tls", "tls_method", "TLSv1")

The POODLE Attack (CVE-2014-3566)
After more than a week of persistent rumours, yesterday (Oct 14) we
finally learned about the new SSL 3 vulnerability everyone was afraid
of. The so-called POODLE attack
<http://googleonlinesecurity.blogspot.com.au/2014/10/this-poodle-bites-exploiting-ssl-30.html>
is a problem in the CBC encryption scheme as implemented in the SSL 3
protocol. (Other protocols are not vulnerable because this area had been
strengthened in TLS 1.0.) Conceptually, the vulnerability is very
similar to the 2011 BEAST exploit. In order to successfully exploit
POODLE the attacker must be able to inject malicious JavaScript into the
victim's browser and also be able to observe and manipulate encrypted
network traffic on the wire. As far as MITM attacks go, this one is
complicated, but easier to execute than BEAST because it doesn't require
any special browser plugins. If you care to learn the details, you can
find them in the short paper
<https://www.openssl.org/%7Ebodo/ssl-poodle.pdf> or in Adam Langley's
blog post <https://www.imperialviolet.org/2014/10/14/poodle.html>.
