Transaction multi-signature validation looks not finished.

Because output is not filled and has zero values condition on line 569 will be always true and validation always gonna fail.

karbo/src/CryptoNoteCore/TransactionValidator.cpp

Line 569 in 8dde91c

if (outputKeyIndex == output.keys.size()) {

karbo/src/CryptoNoteCore/TransactionValidator.cpp

Lines 564 to 575 in 8dde91c

	CryptoNote::MultisignatureOutput output;
	size_t inputSignatureIndex = 0;
	size_t outputKeyIndex = 0;
	while (inputSignatureIndex < in.signatureCount) {
	if (outputKeyIndex == output.keys.size()) {
	m_validationResult.errorCode = CryptoNote::error::TransactionValidationError::INPUT_INVALID_SIGNATURES;
	m_validationResult.errorMessage = "Transaction has input with invalid signature";
	return false;
	}
