Descriptions

The get_server_hello function in the SSLv2 client code in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows remote servers to cause a denial of service (client crash) via unknown vectors that trigger a null pointer dereference.

La función get_server_hello código del cliente SSLv2 en OpenSSL 0.9.7 anterior a 0.9.7l, 0.9.8 anterior a 0.9.8d, y versiones anteriores permite a servidores remotos provocar una denegación de servicio (caída del cliente) mediante vectores desconocidos que disparan un referencia a un puntero nulo.
