I've encountered a serious bug in OpenSSL 1.0.1 on Ubuntu 12.04:

<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=665452>

<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=666051> <- dated Oct 3 2012!

The gist of it is that I'm able to connect to some servers but not others. Connecting to google works:

openssl s\_client -connect mail.google.com:443 -debug -state -msg -CAfile /etc/ssl/certs/ca-certificates.crt

```

But connecting to facebook doesn't:

openssl s\_client -connect graph.facebook.com:443 -debug -state -msg -CAfile /etc/ssl/certs/ca-certificates.crt -cipher SRP-AES-256-CBC-SHA

```

The facebook connection either hangs after the client sends its hello buffer and never receives the server hello response, or returns with an error code if I pass in a cipher it recognizes. This happens with both -tls1 and -ssl3. I've tried every parameter to openssl I can think of.

apt-cache showpkg openssl

```
...
Provides:
1.0.1-4ubuntu5.5 -
1.0.1-4ubuntu5.3 -
1.0.1-4ubuntu3 -

```

I've also tried every parameter I can think of to curl but with no success, because it uses openssl under the hood.

I'm concerned that Ubuntu can't establish secure connections (an astounding statement, I realize). After two solid days of beating my head against this problem, I'm basically praying at this point that someone knows a workaround. I'm considering a downgrade to OpenSSL 1.0.0 or using libcurl4-dev with gnutls-dev instead. Both solutions leave a rotten taste in my mouth. Thanks in advance for any help you can provide.

P.S. all of this work is so that my server can interface with external https REST APIs. I consider this a fundamental requirement in any webserver today, no excuses.

UPDATE: Here is my output without passing a cipher. It doesn't matter if I pass -CAfile or not either:

openssl s\_client -connect graph.facebook.com:443 -debug -state -msg -CAfile /etc/ssl/certs/ca-certificates.crt
