Some time back, to fix POODLE, I tried to fix with cipher suite, but still
I can use the the protocol SSLv3.
The server responds with
openssl s_client -connect ip:port -ssl3
So The fix should come using SSL_CTX_set_options. I understand since you
are using the compiled binary, you may not be in a position to use this
May be you can try with the latest version of openssl with the POODLE fix.
