I read release notes of 6.4.2.6-4.1.3.5 and is valid for IAP93 and it solves:
WPA2 Key Reinstallation Vulnerabilities - CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-
13080, CVE-2017-13081, CVE-2017-13082, CVE-2017-13084, CVE-2017-13086, CVE-2017-13087, and
CVE-2017-13088.
So I´ll install it.
