Descriptions
hostapd before 2.6 does not prevent use of the low-quality PRNG that is reached by an os_random() function call.
hostapd, en versiones anteriores a la 2.6, no evita el uso de un PRNG de baja calidad que se alcanza mediante una llamada de función os_random().
It was discovered that wpa_supplicant and hostapd were vulnerable to a side channel attack against EAP-pwd. A remote attacker could possibly use this issue to recover certain passwords. Mathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly validated received scalar and element values in EAP-pwd-Commit messages. A remote attacker could possibly use this issue to perform a reflection attack and authenticate without the appropriate password. Various other issues were also addressed.
