nginx default config has SSLv3 enabled, makes sites using default config options vulnerable to POODLE

[Thomas Ward]

The included `default` config file contains a commented-out section for SSL.

That SSL section has the SSLv3 parameter provided for `ssl_protocols`. This means that systems are vulnerable to SSLv3 and the POODLE vulnerability.

Can we remove that from the default section, even though it's commented out, so users don't use the insecure SSLv3 protocol anymore?

------

NGINX Project:
In the PPAs, this affects all versions of the package in both Stable and Mainline.

------

Ubuntu Project:

In Ubuntu, this affects the Precise, Trusty, and Utopic versions of the package.

This change was already made/committed in Debian Unstable.

In discussion with mdeslaur on IRC, I'm attaching DebDiffs for Ubuntu in the off chance the release team wishes to push these changes.

A few extra details as to why this is extremely relevant to being pushed and updated: A lot of newbie users that we see in the NGINX IRC channel for support end up using the default configuration file(s) as a template/law for their sites, and we end up seeing them just uncomment the SSL portion and use it. That opens them up to the POODLE vulnerability.

Upstream, in Debian, this was revised per POODLE so newbies wouldn't be exposing themselves to vulnerability, hence the rationale for this perhaps being pushed/updated. Unfortunately, all versions of nginx (including Lucid, which is being ignored intentionally) are impacted by POODLE and SSLv3, so it's better to just remove the SSLv3 protocol from the ssl_protocols line, mainly to prevent newbies from making their systems open to attack.

NOTE: I didn't know where to target this for Utopic, so I just targeted it to 'utopic'. Please change that if it is not valid.
