Name of the Vulnerable Software and Affected Versions Vyper versions prior to 0.3.2

Description The return of <iface>.returns int128() is not validated to fall within the bounds of int128, which can result in a misinterpretation of the integer value and lead to incorrect behavior. As of v0.3.0, <iface>.returns int128() is validated in simple expressions, but not complex expressions.

Recommendations For versions prior to 0.3.2, upgrade to version 0.3.2 or later to resolve the issue. As a temporary workaround, break up operations involving external calls into multiple statements, such as assigning the result of <iface>.returns int128() to a variable before further processing.
