    </p>
  </description>
  <impact type="normal">
    <p>A local attacker could provide specially-crafted input to an application
      using D-Bus which would cause _dbus_printf_string_upper_bound() to return
      1024 bytes and crash, causing a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All D-Bus users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-apps/dbus-1.6.12"
    </code>
