"This update for wpa_supplicant fixes the security 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.

    CVE-2017-13088]

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
