Descriptions

The BN_GF2m_mod_inv function in crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b does not properly handle ECParameters structures in which the curve is over a malformed binary polynomial field, which allows remote attackers to cause a denial of service (infinite loop) via a session that uses an Elliptic Curve algorithm, as demonstrated by an attack against a server that supports client authentication.

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.
