CVE-2022-24788 · CRITICAL Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. Versions of vyper prior to 0.3.2 suffer from a potential buffer overrun. Importing a function from a JSON interface which returns `bytes` generates bytecode which does not clamp bytes length, potentially resulting in a buffer overrun. Users are advised to upgrade. There are no known workarounds for this issue.
