Is this only an issue for those using Google Chrome? I haven't had any SSL issues with Github all day using Firefox.

No, git fetch from MacOSX 10.10 command line as well:

    Maxims-MacBook-Air:walk maximveksler$ git up
    Fetching origin
    fatal: unable to access ‘https://github.com/maximveksler/walk.git/': SSL certificate problem: Invalid certificate chain
    error: Could not fetch origin
    `git fetch` failed
