No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

resolv.c in the DNS resolver in uIP, and dns.c in the DNS resolver in lwIP 1.4.1 and earlier, does not use random values for ID fields and source ports of DNS query packets, which makes it easier for man-in-the-middle attackers to conduct cache-poisoning attacks via spoofed reply packets.
