    Summary: Incorrect computation for some invalid field elements in crypto/elliptic

    Details: Some big.Int values that are not valid field elements (negative or overflowing) might cause Curve.IsOnCurve to incorrectly return true. Operating on those values may cause a panic or an invalid curve operation. Note that Unmarshal will never return such values.
