[vyper] Buffer Overflow in vyper

Impact

Importing a function from a JSON interface which returns bytes generates bytecode which does not clamp bytes length, potentially resulting in a buffer overrun.

Patches

0.3.2 (as of https://github.com/vyperlang/vyper/commit/049dbdc647b2ce838fae7c188e6bb09cf16e470b)

Workarounds

Use .vy interfaces.
