SUSE SLES11 Security Update : wpa_supplicant (SUSE-SU-2017:2752-1) (KRACK)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

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.

CVE-2017-13080, CVE-2017-13081, CVE-2017-13087,
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.
