Descriptions

In OpenSSL 1.1.0 before 1.1.0d, if a malicious server supplies bad parameters for a DHE or ECDHE key exchange then this can result in the client attempting to dereference a NULL pointer leading to a client crash. This could be exploited in a Denial of Service attack.

En OpenSSL versión 1.1.0 anterior a 1.1.0d, si un servidor malicioso suministra parámetros incorrectos para un intercambio de claves DHE o ECDHE, entonces esto puede resultar en que el cliente intente desreferenciar un puntero NULL que conduce a un bloqueo del cliente. Esto podría ser explotado en un ataque de denegación de servicio.
