  <background>
    <p>
    Squid is a multi-protocol proxy server.
    </p>
  </background>
  <description>
    <p>
    Squid fails to correctly handle ftp:// URI's. There is also an error in
    the external_acl queue which can cause an infinite looping condition.
    </p>
  </description>
  <impact type="normal">
    <p>
    An attacker could attempt to retrieve a specially crafted URI via a
    Squid server causing the service to crash. If an attacker could
    generate a sufficiently high load on the Squid services, they could
    cause a Denial of Service by forcing Squid into an infinite loop.
    </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-2.6.7"</code>
  </resolution>
