Overview
Affected versions of this package are vulnerable to Integer Coercion Error due to incorrect implementation of the SHL, SHR, and SAR operations. Smart contracts that ask for shifts between approximately 2 billion and 4 billion bits (nonsensical but valid values for the operation) will fail to execute and hence fail to validate.
