How to fix?

There is no fixed version for dproxy.

Overview

Affected versions of this package are vulnerable to Man-in-the-Middle (MitM) due to the usage of a static UDP source port (selected randomly only at boot time) in upstream queries sent to DNS resolvers, which allows DNS cache poisoning as there is not enough entropy to prevent traffic injection attacks.
