Descriptions

The ssl3_take_mac function in ssl/s3_both.c in OpenSSL 1.0.1 before 1.0.1f allows remote TLS servers to cause a denial of service (NULL pointer dereference and application crash) via a crafted Next Protocol Negotiation record in a TLS handshake.

La función ssl3_take_mac en ssl/s3_both.c en OpenSSL 1.0.1 anterior a 1.0.1f permite a los servidores TLS remotos provocar una denegación de servicio (referencia a un puntero NULL y caída de aplicación) a través de un registro Next Protocol Negotiation modificado en un TLS handshake.
