  <background>
    <p>Icecast is an open source alternative to shoutcast that supports mp3,
      ogg (vorbis/theora) and aac streaming.

  <description>
    <p>When stream_auth handler is defined for URL authentication and a request
      is sent without login credentials, a Denial of Service condition can
      occur. 
    </p>
    
  </description>
  <impact type="normal">
    <p>A remote attacker could possibly cause a Denial of Service condition.</p>
  </impact>
  <workaround>
    <p>Users of affected versions can change stream_auth mountpoints to use
      password authentication instead.
    </p>
  </workaround>
  <resolution>
    <p>All icecast users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=net-misc/icecast-2.4.2"
    </code>
