  <title>OpenID library for Ruby: Server-Side Request Forgery</title>
  <synopsis>A vulnerability in OpenID library for Ruby at worst might allow an
    attacker to bypass authentication.

  <background>
    <p>A Ruby library for verifying and serving OpenID identities.</p>
  </background>
  <description>
    <p>It was discovered that OpenID library for Ruby performed discovery
      first, and then verification.
    </p>
  </description>
  <impact type="high">
    <p>A remote attacker could possibly change the URL used for discovery and
      trick the server into connecting to the URL. This server in turn could be
      a private server not
      publicly accessible.
    </p>
    
    <p>In addition, if the client that uses this library discloses connection
      errors, this in turn could disclose information from the private server
      to the attacker.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All ruby-openid users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-ruby/ruby-openid-2.9.2"
    </code>
