Fix ECIES invalid-curve handling in RLPx handshake (reject invalid ephemeral pubkeys early) - Add curve validation in crypto/ecies.GenerateShared to reject invalid public keys before ECDH. - Update RLPx PoC test to assert invalid curve points fail with ErrInvalidPublicKey. Motivation / Context RLPx handshake uses ECIES decryption on unauthenticated network input. Prior to this change, an invalid-curve ephemeral public key would proceed into ECDH and only fail at MAC verification, returning ErrInvalidMessage. This allows an oracle on decrypt success/failure and leaves the code path vulnerable to invalid-curve/small-subgroup attacks. The fix enforces IsOnCurve validation up front. |
