A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface dnsmasq uses a fixed port while forwarding queries. An attacker on the network able to find the outgoing port used by dnsmasq only needs to guess the random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier. The highest threat from this vulnerability is to data integrity.
