Data Corruption

vyper causes data corruption. Incorrect data handling allows an attacker to cause a data corruption via certain Web3 libraries with Vyper-deploy forwarder proxy contracts using Vyper's built-in createforwarderto function...

VVE-2021-0002: Incorrect `returndatasize` when using simple forwarder proxies deployed prior to EIP-1167 adoption

Background @tjayrush reported a data handling issue with certain Web3 libraries using Vyper-deploy forwarder proxy contracts using our Vyper's built-in createforwarderto function prior to our change to support EIP-1167 style forwarder proxies. Impact If you are an end user of a forwarder-style...

Information Disclosure

vyper is vulnerable to information disclosure. Improper handling of integer types in the Vyper interfaces could allow a user to read an interface that returns a uint8 value to be stored into a uint256 variable without any explicit casting or input validation...

GHSA-MR6R-MVW4-736G Vyper interfaces returning integer types less than 256 bits can be manipulated if uint256 is used

VVE-2020-0001 Earlier today, we received a responsible disclosure of a potential issue from @montyly security researcher at @trailofbits for Vyper users who make assumptions about what values certain interface types can return. Impact We determined the issue to be mild and unlikely to be exploite...
