    Ruby is an interpreted scripting language for quick and easy
    object-oriented programming. Ruby's CGI module can be used to build web
    applications.

  <description>
    <p>
    Ruby's developers found and fixed an issue in the CGI module that
    can be triggered remotely and cause an infinite loop.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could trigger the vulnerability through an
    exposed Ruby web application and cause the server to use unnecessary
    CPU resources, potentially resulting in a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
