CVE-2022-24845: Integer Overflow or Wraparound

April 13, 2022 (updated August 2, 2023)

Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. In affected versions, the return of <iface>.returns_int128() is not validated to fall within the bounds of int128. This issue can result in a misinterpretation of the integer value and lead to incorrect behavior. As of v0.3.0, <iface>.returns_int128() is validated in simple expressions, but not complex expressions. Users are advised to upgrade. There is no known workaround for this issue.
