Vyper 安全漏洞

Vyper is the Pythonic smart contract language for EVM. A security vulnerability exists in versions of Vyper prior to 0.3.8 that stems from the ability to send funds to a default function in a contract with multiple regular non-payable functions, even if the default function is marked as non-payab...

PYSEC-2023-79

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...
