Overview
vyper is a Pythonic Smart Contract Language for the EVM.
Affected versions of this package are vulnerable to Out-of-bounds Read due to improper handling of external contract calls with overlapping input and return buffers. An attacker can cause the contract to overrun the returned data and read return data from the input buffer by supplying malformed return data that is not properly checked against the returned value's length.
