CVE-2016-9121

go-jose before 1.0.4 suffers from an invalid curve attack for the ECDH-ES algorithm. When deriving a shared key using ECDH-ES for an encrypted message, go-jose neglected to check that the received public key on a message is on the same curve as the static private key of the receiver, thus making it vulnerable to an invalid curve attack.

When using ECDH-ES an attacker can mount an invalid curve attack during decryption as the supplied public key is not checked to be on the same curve as the receivers private key.

go-jose en versiones anteriores a 1.0.4 sufre de un ataque de curva no válida para el algoritmo ECDH-ES. Al derivar una clave compartida usando ECDH-ES para un mensaje encriptado, go-jose descuidado para comprobar que la clave pública recibida en un mensaje está en la misma curva que la clave privada estática del receptor, haciéndola vulnerable a una curva no válida ataque.
