SCA: security update for vyper (GHSA-6m97-7527-mh74)

high Tenable Self-Hosted Container Security Plugin ID 411521

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine (EVM). Contracts containing
large arrays might underallocate the number of slots they need by 1. Prior to v0.3.8, the calculation to
determine how many slots a storage variable needed used `math.ceil(type_.size_in_bytes / 32)`. The
intermediate floating point step can produce a rounding error if there are enough bits set in the IEEE-754
mantissa. Roughly speaking, if `type_.size_in_bytes` is large (> 2**46), and slightly less than a power of
2, the calculation can overestimate how many slots are needed by 1. If `type_.size_in_bytes` is slightly
more than a power of 2, the calculation can underestimate how many slots are needed by 1. This issue is
patched in version 0.3.8. (CVE-2023-46247)
