CVE-2023-30629
Good to know:
Date: April 24, 2023
Vyper is a Pythonic Smart Contract Language for the ethereum virtual machine. In versions 0.3.1 through 0.3.7, the Vyper compiler generates the wrong bytecode. Any contract that uses the "raw_call" with "revert_on_failure=False" and "max_outsize=0" receives the wrong response from "raw_call". Depending on the memory garbage, the result can be either "True" or "False". A patch is available and, as of time of publication, anticipated to be part of Vyper 0.3.8. As a workaround, one may always put "max_outsize>0".
