CVE-2016-4477 is fixed in 3 products on 1 platform, first by hostapd 1:2.4-0ubuntu10, released October 15, 2017. It is not reported as exploited. Patch Radar priority: Routine.
wpa_supplicant 0.4.0 through 2.5 does not reject \n and \r characters in passphrase parameters, which allows local users to trigger arbitrary library loading and consequently gain privileges, or cause a denial of service (daemon outage), via a crafted (1) SET, (2) SET_CRED, or (3) SET_NETWORK command.
