Summary

github.com/docker/docker/libnetwork is a package that provides a native Go implementation for connecting containers
Affected versions of this package are vulnerable to Improper Control of a Resource Through its Lifetime, allowing DNS requests from internal networks to be forwarded to an external nameserver, violating the documented expectation that the --internal option will "completely isolate" the internal network. An attacker in control of the authoritative nameserver for a domain could indirectly exfiltrate data through DNS queries made by a compromised container.
