Security update for wpa_supplicant (important)

This update for wpa_supplicant fixes the following issues:

• Several vulnerabilities in standard conforming implementations of the
  WPA2 protocol have been discovered and published under the code name
  KRACK. This update remedies those issues in a backwards compatible
  manner, i.e. the updated wpa_supplicant can interface properly with both
  vulnerable and patched implementations of WPA2, but an attacker won’t be
  able to exploit the KRACK weaknesses in those connections anymore even
  if the other party is still vulnerable. [bsc#1056061, CVE-2017-13078,
