  <background>
    <p>usbmuxd is a USB multiplex daemon for use with Apple iPhone and iPod
      Touch devices.
    </p>
  </background>
  <description>
    <p>The "receive_packet()" function in libusbmuxd.c contains a boundary
      error when parsing the "SerialNumber" field of a USB device, which could
      cause a heap-based buffer overflow.
    </p>
  </description>
  <impact type="normal">
    <p>An attacker could gain physical access or entice a user to connect to a
      malicious USB device, possibly resulting in execution of arbitrary code
      with the privileges of the "usbmux" user.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All usbmuxd users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-pda/usbmuxd-1.0.7-r1"
    </code>
