  <affected>
    <package name="net-proxy/squid" auto="yes" arch="*">
      <unaffected range="ge">2.6.12</unaffected>

  <background>
    <p>
    Squid is a multi-protocol proxy server.
    </p>
  </background>
  <description>
    <p>
    Squid incorrectly handles TRACE requests that contain a "Max-Forwards"
    header field with value "0" in the clientProcessRequest() function.
    </p>
  </description>
  <impact type="low">
    <p>
    A remote attacker can send specially crafted TRACE HTTP requests that
    will terminate the child process. A quickly repeated attack will lead
    to a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Squid users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-proxy/squid-2.6.12"</code>
  </resolution>
