Summary

CVE-2023-46247 is a vulnerability affecting the Vyper smart contract language for the Ethereum Virtual Machine (EVM). This vulnerability occurs when contracts with large arrays underallocate the number of slots they need by 1. The issue stems from a rounding error in the calculation to determine the number of storage variable slots needed. If the size of the variable is slightly less than or slightly more than a power of 2, the calculation can underestimate or overestimate the required slots by 1. This vulnerability has been patched in version 0.3.8. The potential danger it poses to an organization depends on their use of Vyper contracts and could result in unexpected behavior or manipulation of data stored in these contracts.
