    Ruby is a dynamic, open source programming language with a focus on
    simplicity and productivity.

  <description>
    <p>
    Zed Shaw, Jeremy Kemper, and Jamis Buck of the Mongrel project reported
    that the CGI library shipped with Ruby is vulnerable to a remote Denial
    of Service by an unauthenticated user.
    </p>
  </description>
  <impact type="normal">
    <p>
    The vulnerability can be exploited by sending the cgi.rb library an
    HTTP request with multipart MIME encoding that contains a malformed
    MIME boundary specifier beginning with "-" instead of "--". Successful
    exploitation of the vulnerability causes the library to go into an
    infinite loop waiting for additional nonexistent input.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Ruby users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=dev-lang/ruby-1.8.5-r3"</code>
  </resolution>
