    Laurent Butti, Jerome Raznieski and Julien Tinnes reported a buffer
    overflow in the encode_ie() and the giwscan_cb() functions from
    ieee80211_wireless.c.
  
Impact :

    A remote attacker could send specially crafted wireless WPA packets
    containing malicious RSN Information Headers (IE) that could
    potentially lead to the remote execution of arbitrary code as the root
    user.
  
Workaround :

    There is no known workaround at this time."
