CVE-2024-32648 vyper default functions don't respect nonreentrancy keys

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. Prior to version 0.3.0, default functions don't respect nonreentrancy keys and the lock isn't emitted. No vulnerable production contracts were found. Additionally, using a lock on a default function is a very sparsely...

CVE-2024-32647

Vyper vulnerability CVE-2024-32647 concerns the create_from_blueprint builtin prior to version 0.3.11. The root cause is that the _build_create_IR path does not cache the args parameter on the stack when raw_args=True and args have side-effects, allowing the argument to be evaluated multiple time...

CVE-2024-32646

Vyper CVE-2024-32646 affects the Pythonic smart contract language. The vulnerability concerns the builtin slice when the buffer is msg.data, self.code, or .code and either the start or length has side-effects, causing a double evaluation of those side-effects. It is triggerable only in versions e...

CVE-2024-32645 vyper performs incorrect topic logging in raw_log

Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, incorrect values can be logged when rawlog builtin is called with memory or storage arguments to be used as topics.
