Wrong blocksPerYear in WhitePaperInterestRateModel

Lines of code Vulnerability details Impact Venus is deployed on BNB Chain instead of Ethereum. Their block times are different. And WhitePaperInterestRateModel.sol is modified from compound. Therefore, blocksPerYear should be modified or Venus would get the wrong rate when using...

CVE-2023-32059

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, internal calls with default arguments are compiled incorrectly. Depending on the number of arguments provided in the call, the defaults are added not right-to-left, but left-to-right. If the type...

CVE-2023-32058

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, due to missing overflow check for loop variables, by assigning the iterator of a loop to a variable, it is possible to overflow the type of the latter. The issue seems to happen only in loops of...

CVE-2023-31146

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, during codegen, the length word of a dynarray is written before the data, which can result in out-of-bounds array access in the case where the dynarray is on both the lhs and rhs of an assignment...

CVE-2023-32059

The CVE-2023-32059 entry describes a vulnerability in Vyper (Pythonic smart contract language for EVM) prior to version 0.3.8. Root cause: internal calls with default arguments are compiled with incorrect ordering, causing defaults to be applied left-to-right instead of right-to-left, and in some...

CVE-2023-32059 Vyper vulnerable to incorrect ordering of arguments for kwargs passed to internal calls

Depending on the number of arguments provided in the call, the defaults are added not right-to-left, but left-to-right. If the type...

CVE-2023-32058 Vyper vulnerable to integer overflow in loop

Vyper is a Pythonic smart contract language for the Ethereum virtual machine. Prior to version 0.3.8, due to missing overflow check for loop variables, by assigning the iterator of a loop to a variable, it is possible to overflow the type of the latter. The issue seems to happen only in loops of...

CVE-2023-32058

CVE-2023-32058 affects the Vyper language (EVM smart contracts). Prior to version 0.3.8, there was a missing overflow check for loop variables when iterating with patterns like for i in range(a, a + N). This could cause the loop variable’s type to overflow. The issue appears specifically in for i...
