Red Hat Security Advisory 2013-1203-01 - RubyGems is the Ruby standard for publishing and managing third-party libraries. It was found that, when using RubyGems, the connection could be redirected from HTTPS to HTTP. This could lead to a user believing they are installing a gem via HTTPS, when the connection may have been silently downgraded to HTTP. It was found that RubyGems did not verify SSL connections. This could lead to man-in-the-middle attacks.
