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...
