Descriptions

Bitcoin Core before 0.14 allows an attacker to create an ostensibly valid SPV proof for a payment to a victim who uses an SPV wallet, even if that payment did not actually occur. Completing the attack would cost more than a million dollars, and is relevant mainly only in situations where an autonomous system relies solely on an SPV proof for transactions of a greater dollar amount.

Bitcoin Core versiones anteriores a 0.14, permite a un atacante crear una prueba SPV ostensiblemente válida para un pago a una víctima que utiliza una billetera SPV, incluso si ese pago no es realizado realmente. Completar el ataque costaría más de un millón de dólares, y es relevante principalmente solo en situaciones donde un sistema autónomo se basa únicamente en una prueba SPV para transacciones de un monto mayor en dólares.
