Univention Corporate Server 4.2 erratum 284 (security)

This update addresses the following issue(s):
* Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11r allows
  reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during
  the fast BSS transmission (FT) handshake, allowing an attacker within radio
  range to replay, decrypt, or spoof frames. (CVE-2017-13082)
* 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)
* Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows
  reinstallation of the Integrity Group Temporal Key (IGTK) during the group
  key handshake, allowing an attacker within radio range to spoof frames from
  access points to clients. (CVE-2017-13081)
* Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Tunneled
  Direct-Link Setup (TDLS) Peer Key (TPK) during the TDLS handshake, allowing
  an attacker within radio range to replay, decrypt, or spoof frames.
  (CVE-2017-13086)
* Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows
  reinstallation of the Group Temporal Key (GTK) when processing a Wireless
  Network Management (WNM) Sleep Mode Response frame, allowing an attacker
  within radio range to replay frames from access points to clients.
  (CVE-2017-13087)
* Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows
  reinstallation of the Integrity Group Temporal Key (IGTK) when processing a
  Wireless Network Management (WNM) Sleep Mode Response frame, allowing an
  attacker within radio range to replay frames from access points to clients.
  (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) 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)
* 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. (CVE-2017-13077)
