Description

This is a security issue as well as a reliability one for packages that use the local network for testing purpose.
See https://github.com/opencontainers/runc/issues/201 for discussions and possible solutions. e.g.:

Determine which approach fits the project and verify that containers no longer share the host's localhost while retaining the required host-network behavior.
