Descripción
La función BN_GF2m_mod_inv en crypto/bn/bn_gf2m.c en OpenSSL anterior a 0.9.8s, 1.0.0 anterior a 1.0.0e, 1.0.1 anterior a 1.0.1n, y 1.0.2 anterior a 1.0.2b no maneja correctamente las estructuras ECParameters en las cuales la curva está por un campo polinomio binario malformado, lo que permite a atacantes remotos causar una denegación de servicio (bucle infinito) a través de una sesión que utiliza un algoritmo Elliptic Curve, tal y como fue demostrado mediante un ataque sobre un servidor que soporta la autenticación de clientes.
