SCA: security update for vyper (GHSA-2q8v-3gqq-4f8p)
critical Tenable Self-Hosted Container Security Plugin ID 421486
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. The `concat` built-in can
write over the bounds of the memory buffer that was allocated for it and thus overwrite existing valid
data. The root cause is that the `build_IR` for `concat` doesn't properly adhere to the API of copy
functions (for `>=0.3.2` the `copy_bytes` function). A contract search was performed and no vulnerable
contracts were found in production. The buffer overflow can result in the change of semantics of the
contract. The overflow is length-dependent and thus it might go unnoticed during contract testing.
However, certainly not all usages of concat will result in overwritten valid data as we require it to be
in an internal function and close to the return statement where other memory allocations don't occur. This
issue has been addressed in 0.4.0. (CVE-2024-22419)
