Bug description:
We configure keystone to use SSL always. Due to the poodle issue, I was trying to configure keystone to disable SSLv3 completely.
http://googleonlinesecurity.blogspot.fi/2014/10/this-poodle-bites-exploiting-ssl-30.html
https://www.openssl.org/~bodo/ssl-poodle.pdf
It seems that keystone has no support for configring SSL versions, nor
ciphers.
If I'm not mistaken the relevant code is in the start function in
common/environment/eventlet_server.py
It calls
eventlet.wrap_ssl
but with no SSL version nor cipher options. Since the interface is identical, I assume it uses ssl.wrap_socket. The default here seems to be PROTOCOL_SSLv23 (SSL2 disabled), which would make this vulnerable to the poodle issue.
SSL conifgs should probably be possible to be set in the config file
(with sane defaults), so that current and newly detected weak ciphers
can be disabled without code changes.
