CVE-2024-32481 vyper's range(start, start + N) reverts for negative numbers

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. Starting in version 0.3.8 and prior to version 0.4.0b1, when looping over a range of the form rangestart, start + N, if start is negative, the execution will always revert. This issue is caused by an incorrect assertion...

CVE-2024-32644

Summary: CVE-2024-32644 affects Evmos pre-17.0.0. A state synchronization bug in stateDB.Commit() compares dirtyStorage to originStorage and only writes when they differ, which can allow non-atomic transactions and potentially mint arbitrary tokens or drain funds through creative smart-contract i...

CVE-2024-32644 Evmos' transaction execution not accounting for all state transition after interaction with precompiles

Evmos is a scalable, high-throughput Proof-of-Stake EVM blockchain that is fully compatible and interoperable with Ethereum. Prior to 17.0.0, there is a way to mint arbitrary tokens due to the possibility to have two different states not in sync during the execution of a transaction. The exploit ...
