Two vulnerabilities have been identified in Ruby prior to version
The vendor has provided the following description for this
"This release includes two security fixes in RubyGems.
Turn on verification of server SSL certs
Disallow redirects from https to http" 
"This release increases the security used when RubyGems is talking to
an https server. If you use a custom RubyGems server over SSL, this
release will cause RubyGems to no longer connect unless your SSL cert
is globally valid.
You can configure SSL certificate usage in RubyGems through the
:sslca_cert and :sslverify_mode options in ~/.gemrc and /etc/gemrc. The
recommended way is to set :ssl_ca_cert to the CA certificate for your
server or a certificate bundle containing your CA certification.
You may also set :sslverifymode to 0 to completely disable SSL
certificate checks, but this is not recommended." 
The vendor recommends upgrading to the latest version of Ruby
to correct these issues. 
 Ruby 1.9.3-p194 is released
