CVE-2014-8164: Critical severity red hat cloudforms management engine vulnerability
A insecure configuration for certificate verification (http.verifymode = OpenSSL::SSL::VERIFYNONE) may lead to verification bypass in Red Hat CloudForms 5.x.

CloudForms: http.verifymode = OpenSSL::SSL::VERIFYNONE
From the email:
Ok so two main things here, firstly I would prefer to fix this all at once, looking at the code there's a whole bunch of instances of "http.verifymode = OpenSSL::SSL::VERIFYNONE" (11 or so out of 17 total calls for http.verify), so even if we fix this default one, there would still be the 11 instances, so rather than do several fixes and end up with multiple CVE's I'd rather do this all at once. Now as how to fix it:
1) removing any uneeded code with respect to this SSL stuff (apparently a few may not be needed anymore?)
2) By default change it so that we check SSL correctly, however for backwards compatibility of existing installations, and for demos we want to allow the old behaviour, so some switch in a config file/web interface like "Allow self signed certs" with a warning/explanation.
3) To protect against attacks (e.g. with a self signed cert, we can't check it properly, so a man in the middle attack is pretty easy) we could harden it by caching the certificates the first time we see them, and then checking against that cached copy. So in theory the first time you access it (right after setup) is safe, we cache that, and in future any changes would cause an alarm, basically buying us most of what you would get by using a "Real" certificate.
So I would say #2 is mandatory, #1 is always good (removing dead code) and #3 would be very nice to have, but really if people want security they can buy certificates for not much money.
