CVE-2016-4476 [HIGH] CVE-2016-4476 wpa_supplicant, hostapd: denial of service via crafted WPA/WPA2 passphrase parameter
CVE-2016-4476 wpa_supplicant, hostapd: denial of service via crafted WPA/WPA2 passphrase parameter
A vulnerability was found in how hostapd and wpa_supplicant writes the
configuration file update for the WPA/WPA2 passphrase parameter. If this
parameter has been updated to include control characters either through
a WPS operation or through local configuration change over the
wpa_supplicant control interface, the resulting configuration file may
prevent the hostapd and wpa_supplicant from starting when the updated
file is used.
