  <description>
    <p>
    Tor contains a heap-based buffer overflow in the processing of user or
    attacker supplied data. No additional information is available.
    </p>
  </description>
  <impact type="high">
    <p>
    Successful exploitation of this vulnerability may allow an
    unauthenticated remote attacker to execute arbitrary code with the
    permissions of the Tor user, or to cause a Denial of Service.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Tor users should upgrade to the latest stable version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-misc/tor-0.2.1.28"</code>
