As per title, https://hub.docker.com/layers/istio/coredns-plugin/0.2-istio-1.1/images/sha256-964eca01e487bcedcc769dd22644a4272daebf079b64170dd6bab16662651b99?context=explore contains the Shellshock vulnerability and hasn't been built in 2 years. Would it be possible for an updated version of the image to be built and released officially with the exploit patched?

Bug description
I setup a multi-cluster, I configured an elb domain in service entry.
However, sometimes the connect to elb will fail for next 5 minutes.
So I changed dnsRefreshRate from 300s to 60s, in configure map istio and istio-sidecar-injector. Now the elb will fail for next 1 minute sometimes but more frequently.
Here is log in coredns, why it add .global for domain?
