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)
