Dao has unchecked transfers

Handle heiho1 Vulnerability details Impact Dao.moveBASEBalanceaddress and Dao.handleTransferInaddress,uint256 do not check transfer return values on lines 220 and 266. If the token implementation returns false and does not revert, then potentially the user can deposit for free. Proof of Concept...

Expired transfers will lock user funds on the sending chain

Handle 0xRajeev Vulnerability details Impact The cancelling relayer is being paid in receivingAssetId on the sendingChain instead of in sendingAssetID. If the user relies on a relayer to cancel transactions and that receivingAssetId asset does not exist on the sending chain assuming only...

TransactionIDs may not be reused by user

Handle cmichel Vulnerability details Vulnerability Details The fulfill signature is only on txData.transactionId, relayerFee which allows the router to steal user funds for cross-chain transfers that go to the same router and use the same transaction ID as an earlier transfer. Example: a successf...

Funds are sent twice on callTo errors

Handle cmichel Vulnerability details Vulnerability Details The fulfill transaction on the receiving chain tries to call the addFunds and execute actions on txData.callTo. When any of the calls reverts, the funds are sent to the txData.receivingAddress. The txData.callTo is user-controlled and an...

User prepare can be denied

Handle cmichel Vulnerability details Vulnerability Details Upon observing a prepare transaction, an attacker can frontrun it with the same invariantData but an amount of a single wei. This inserts a value into variantTransactionDatadigest and the original transcation will fail because of the...

Funds can be stolen because of approval + send

Handle cmichel Vulnerability details Vulnerability Details The fulfill transaction on the receiving chain first approves the txData.callTo contract with the toSend amount. It then tries to call the addFunds and execute actions on txData.callTo. When any of the calls reverts, the funds are sent to...

Lack of return value check or use of SafeERC20 wrappers for token transfers

Handle 0xRajeev Vulnerability details Impact ERC20 tokens are specified to return a boolean value on token transfer and transferFrom. However, tokens may not adhere to the spec and return no value for success/failure. Checking the return values of ERC20 token transfers is therefore important to...

Data privacy: What's new in cross-border transfers? The Standard Contractual Clauses

The transfer of personal data between companies and countries is vital for smooth data processing operations. When transferring data out of the European Union, companies are required to comply with the General Data Protection Regulation GDPR which requires that any data that is transferred to a...

Unchecked token transfers

Handle Lucius Vulnerability details Impact The functions transerFrom/transer do not revert on failure and instead simply return false. Without checks on the return values, the transfers could potentially fail silently allowing unexpected issues with certain token pools. E.G. If a user calls depos...

Updated bind packages fix a security vulnerability

Incremental zone transfers IXFR provide a way of transferring changed portions of a zone between servers. An IXFR stream containing SOA records with an owner name other than the transferred zone's apex may cause the receiving named server to inadvertently remove the SOA record for the zone in...

curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library which has the surprising side-effect that if an application sets up multiple concurrent transfers the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario this weakens transport security significantly.
