Descriptions

Libgcrypt before 1.6.5 does not properly perform elliptic-point curve multiplication during decryption, which makes it easier for physically proximate attackers to extract ECDH keys by measuring electromagnetic emanations.

Libgcrypt en versiones anteriores a 1.6.5 no lleva a cabo correctamente la multiplicación de curva de puntos elípticos durante el descifrado, lo que facilita a atacantes físicamente próximos extrarer claves ECDH mediante la lectura de las emanaciones electromagnéticas.
