Hi Shannon,

From what I understand so far a minimum Cipher list of

'RC4:HIGH:!MD5:!aNULL' along with stopping the Client Renegotiating the ciphers seems to resolve the problem.

In Pound the patch allows for two new options to be set: SSLHonorCipherOrder & SSLAllowClientRenegotiation

I've looked in the OpenSSL documentation but I don't seem to be able to find anything that has the same functionality although I'm no expert so I may have just over looked it.

Hi All,

Has anyone looked at the current issue with the BEAST Attack.

I'm looking at https://www.ssllabs.com/ssltest/index.html which can be used for testing SSL Certificates I also use Pound Proxy which I have now patched and this has removed the threat.

However, I don't seem to be able to get the same result from a STunnel installation. If anyone can give some advice that would be great.

~Yours, Scott

Hi Shannon,

After flicking through the OpenSSL documents I'm guessing that from the SSL_CTX_set_options page http://www.openssl.org/docs/ssl/SSL_CTX_set_options.html we need to use * SSL_OP_CIPHER_SERVER_PREFERENCE* but if you put that into your config file as: options = CIPHER_SERVER_PREFERENCE STunnel throws an error about the config file, so at the moment I'm a little stuck.

Hi Scott,

Yes, that's the cipher I'm using which seems to cover everything from a secure ciphers point of view. Any idea how to disable client renegotiations within Stunnel?
