raw_call `value=` kwargs not disabled for static and delegate calls
Résumé
raw_call value= kwargs not disabled for static and delegate calls
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. Vyper compiler allows passing a value in builtin raw_call even if the call is a delegatecall or a staticcall. But in the context of delegatecall and staticcall the handling of value is not possible due to the semantics of the respective opcodes, and vyper will silently ignore the value= argument. If the semantics of the EVM are unknown to the developer, he could suspect that by specifying the value kwarg, exactly the given amount will be sent along to the target. This vulnerability affects 0.3.10 and earlier versions.
