    <p>
    BlueZ is a set of Bluetooth tools and system daemons for Linux.

  <description>
    <p>
    It has been reported that the Bluetooth packet parser does not validate
    string length fields in SDP packets.
    </p>
  </description>
  <impact type="normal">
    <p>
    A physically proximate attacker using a Bluetooth device with an
    already established trust relationship could send specially crafted
    requests, possibly leading to arbitrary code execution or a crash.
    Exploitation may also be triggered by a local attacker registering a
    service record via a UNIX socket or D-Bus interface.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All bluez-utils users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-wireless/bluez-utils-3.36"</code>
    <p>
    All bluez-libs users should upgrade to the latest version:
