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 type `for i in range(a, a + N)` as in loops of type `for i in range(start, stop)` and `for i in range(stop)`, the compiler is able to raise a `TypeMismatch` when trying to overflow the variable. The problem has been patched in version 0.3.8.\n\ud83d\udccf Published: 2023-05-11T20:55:35.195Z\n\ud83d\udccf Modified: 2025-01-24T15:57:47.118Z\n\ud83d\udd17 References:\n1. https://github.com/vyperlang/vyper/security/advisories/GHSA-6r8q-pfpv-7cgj\n2. https://github.com/vyperlang/vyper/commit/3de1415ee77a9244eb04bdb695e249d3ec9ed868", "creation_timestamp": "2025-01-24T16:04:38.000000Z"}, {"uuid": "37195ef4-177d-4ae2-8049-42158b973087", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2023-32058", "type": "seen", "source": "https://t.me/cibsecurity/63927", "content": "\u203c CVE-2023-32058 \u203c\n\nVyper is a Pythonic smart contract language for the Ethereum virtual machine.
