    wpa vulnerability
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    wpa_supplicant could be made to crash, expose memory, or run programs if it
    received specially crafted network traffic.
    Software Description:
    - wpa: client support for WPA and WPA2
    It was discovered that wpa_supplicant incorrectly handled SSID information
    when creating or updating P2P peer entries. A remote attacker could use
    this issue to cause wpa_supplicant to crash, resulting in a denial of
    service, expose memory contents, or possibly execute arbitrary code.
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:

    Ubuntu 14.04 LTS:
      wpasupplicant                   2.1-0ubuntu1.2
