CWE ID 670

Summary

CVE-2023-41052 affects Vyper, a Pythonic Smart Contract Language. In affected versions, the order of evaluation for the arguments of certain built-in functions, specifically `uint256_addmod`, `uint256_mulmod`, `ecadd`, and `ecmul`, does not follow source order. This issue creates a problem when the evaluation of one argument generates side effects that other arguments depend on. A patch is currently under development on pull request #3583. To mitigate this vulnerability, users should ensure that the arguments of expressions using the listed built-ins do not generate side effects, or if one does, that no other argument depends on those side effects.
