Detailsinfo

A vulnerability was found in Vyper (unknown version) and classified as problematic. This issue affects the function uint256_addmod/uint256_mulmod/ecadd/ecmul. The manipulation with an unknown input leads to a control flow vulnerability. Using CWE to declare the problem leads to CWE-670. The code contains a control flow path that does not reflect the algorithm that the path is intended to implement, leading to incorrect behavior any time this path is navigated. Impacted is integrity. The summary by CVE is:

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.

The weakness was published 09/05/2023 as GHSA-4hg4-9mf5-wxxq. It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2023-41052 since 08/22/2023. Technical details of the vulnerability are known, but there is no available exploit.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at github.com.
