    A fix has been issued as per USN-3455-1 . You should update your system with sudo apt-get update && sudo apt-get upgrade. The relevant versions for currently supported releases:

    • Ubuntu 17.04:
      hostapd 2.4-0ubuntu9.1
      wpasupplicant 2.4-0ubuntu9.1
    • Ubuntu 16.04 LTS:
      hostapd 2.4-0ubuntu6.2
      wpasupplicant 2.4-0ubuntu6.2
    • Ubuntu 14.04 LTS:
      hostapd 2.1-0ubuntu1.5
      wpasupplicant 2.1-0ubuntu1.5

    You should see an update of wpasupplicant during the update. More information about the attack is available on the GitHub page.
