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

Low Nessus Plugin ID 103920

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.

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.
