Wi-Fi protected access (WPA and WPA2) allows reinstallation of the pairwise key in the four-way handshake.CVE-2017-13077 has been assigned to this vulnerability. A CVSS v3 base score of 4.2 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N). Wi-Fi protected access (WPA and WPA2) allows reinstallation of the group temporal key (GTK) during the four-way handshake, allowing an attacker within radio range to replay frames from access points to clients.CVE-2017-13078 has been assigned to this vulnerability. A CVSS v3 base score of 4.2 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N). 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 has been assigned to this vulnerability. A CVSS v3 base score of 5.9 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N). Wi-Fi protected access (WPA and WPA2) allows reinstallation of the group temporal key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients.CVE-2017-13080 has been assigned to this vulnerability. A CVSS v3 base score of 4.2 has been calculated; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N). Wi-Fi protected access (WPA and WPA2) that su…

Security update for wpa_supplicant

Affected: Ubuntu:14.04:LTS: wpa, Ubuntu:16.04:LTS: wpa

Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames.

Multiple security issues and vulnerabilities within the WPA2 standard have been identified and publicized by Mr. Mathy Vanhoef of KU Leuven. These vulnerabilities may allow the reinstallation of a pairwise transient key, a group key, or an integrity key on either a wireless client or a wireless access point (AP). In consequence, an attacker could establish a man-in-the-middle position between AP and client facilitating packet decryption and injection.

Update A / Revision 2 - 2017-11-09 * Added a detailed list of affected products

Update B / Revision 3 - 2018-09-24 * Added firmware update information, see section "Solution"
