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-2023-32058

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...
