Upgrade github.com/coredns/coredns/plugin/pkg/proxy to version 1.11.0 or higher.
Overview
github.com/coredns/coredns/plugin/pkg/proxy is a package that implements a forwarding proxy. It caches an upstream net.Conn for some time, so if the same client returns the upstream's Conn will be precached.
Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') through the DNS resolving process. An attacker can disrupt normal DNS resolution by forging a response targeting the source port of a vulnerable resolver without the need to guess the correct TXID.
