CVE-2023-41052 Information

Description

Vyper is a Pythonic Smart Contract Language. In affected versions the order of evaluation of the arguments of the builtin functions uint256_addmod uint256_mulmod ecadd and ecmul does not follow source order. This behaviour is problematic when the evaluation of one of the arguments produces side effects that other arguments depend on. A patch is currently being developed on pull request 3583. When using builtins from the list above users should make sure that the arguments of the expression do not produce side effects or if one does that no other argument is dependent on those side effects.
