"According to the versions of the wpa_supplicant package installed,
the EulerOS installation on the remote host is affected by the
following vulnerabilities :

  - A new exploitation technique called key reinstallation
    attacks (KRACK) affecting WPA2 has been discovered. A
    remote attacker within Wi-Fi range could exploit these
    attacks to decrypt Wi-Fi traffic or possibly inject
    forged Wi-Fi packets by manipulating cryptographic
    handshakes used by the WPA2 protocol. (CVE-2017-13077,
    CVE-2017-13078, CVE-2017-13080, CVE-2017-13082,
    CVE-2017-13086, CVE-2017-13087, CVE-2017-13088)

  - Wi-Fi Protected Access (WPA and WPA2) that supports
    IEEE 802.11w allows reinstallation of the Integrity
    Group Temporal Key (IGTK) during the four-way
    handshake, allowing an attacker within radio range to
    spoof frames from access points to
    clients.(CVE-2017-13079)

  - Wi-Fi Protected Access (WPA and WPA2) that supports
    IEEE 802.11w allows reinstallation of the Integrity

    handshake, allowing an attacker within radio range to
    spoof frames from access points to
    clients.(CVE-2017-13081)
