More concerned about this statement "Chef sets :verify_none by default", I presumed it was due to issues in Ruby with SSL.  I also assumed it was for *Nix based distros, no experience with Windows.

Can you be more specific Andrew on what you mean by the "ssl fix? Are you concerned that the windows package still does not enforce ssl by default despite including cacert.pem?

To be clear, the work on ssl for Windows isn't yet done — the goal is to validate the server for all ssl endpoints.

The SSL fix makes me sad.  Those familiar with omnibus packaging, how hard would it be to create an alternate Omnibus distro with cert pinnning for Hosted Chef?

Thanks folks, you were all a big help.

There's a patch in 11.6.x alpha (saw on master) that is required for
2.0.0, iirc, something to do with rubygem/format.

You can build your own omnibus-chef packages (and screw around with
the project/software definitions, etc) really easily, check out the
following projects:

https://github.com/opscode/omnibus-chef
https://github.com/opscode/omnibus-software
https://github.com/opscode/omnibus-ruby

I'd advise that if you feel the Opscode bundled omnibus installations
are not up-to-date enough, consider modifying the Ruby software [0]
definition in omnibus-software, pointing your omnibus-chef Gemfile at
your fork/branch and kicking off the build -- you'll get omnibus
packages out of the other end.. Once you have packages, it's trivial
to either host them in a native package repository or bare HTTP.

One might even consider creating their own 'omnibus-software'
repository of definitions to be bundled into omnibus projects for
usage in other projects!

Cheers,

AJ

    I mean, if I recall, Chef still technically supports 1.8, that

            To be clear it's not so much the vulnerability that

            in general and how that works. For example will the next

            Hi,

            What is the policy of Chef releases with regard to Ruby
            releases?

            For example there are ruby 1.9.3-p448 and 2.0.0-p247
            releases that
            fix an SSL vulnerability, will Opscode make an 11.4.4
            release with a
            new embedded Ruby?

            Are we better off using the Chef gem in our managed
            Rubies over the
            Omnibus?



            The relevant bug fix just blocks a potential issue in
            how Ruby
            verifies SSL certificates. Chef sets :verify_none by
            default, so
            there is technically no risk of hitting the bug :-) (the
            astute
            reader will note that this is because there is never any
            validation)
