It appears now I've been bitten by this bug in Apache.  I run a pair of
reverse proxy servers on 12.04 using Apache.  I built these servers last
year and they were working fine up until last week when I ran a dist-
upgrade to update some packages (specifically apache2 and openssl) to
clear up some vulnerabilities identified in a PCI scan.  Since then, one
of the reverse proxies is unable to connect to an internal WebLogics
server due to SSL errors.  Using openssl s_client -connect fails, but
adding -tls1 works.

According to the Apache 2.2 documentation, I should be able to add
"SSLProxyProtocol All -SSLv2 -TLSv1.1 -TLSv1.2" to my reverse proxy
virtual server config, but it doesn't like the "-TLSv1.1 -TLSv1.2".
I've read that those options are only supported in Apache 2.4.

Now I'm basically stuck.  It appears Ubuntu 12.04 has made a change in
openssl that is impossible to workaround in the version of Apache
provided in Ubuntu 12.04.  Downgrading openssl is not an option because
I specifically needed the current version to pass the PCI scan.  I've
asked about updating the WebLogics server, but considering it is a
PeopleSoft server, I suspect that is going to be a challenge.
