Descriptions

The mcrypt_create_iv function in ext/mcrypt/mcrypt.c in PHP before 4.4.7, 5.2.1, and possibly 5.0.x and other PHP 5 versions, calls php_rand_r with an uninitialized seed variable and therefore always generates the same initialization vector (IV), which might allow context-dependent attackers to decrypt certain data more easily because of the guessable encryption keys.

La función mcrypt_create_iv en ext/mcrypt/mcrypt.c en PHP anterior a 4.4.7, 5.2.1, y posiblemente 5.0.x y otras versiones PHP 5, llaman a php_rand_r con una variable de cabeza de serie no inicializada y por lo tanto siempre genera el mismo vector de inicialización (IV), lo cual podría permitir a atacantes dependientes del contexto desencriptar ciertos datos más fácilmente debido a que las claves de cifrado son más fáciles de adivinar.
