Red Hat has released multiple security advisories and updated packages to address the Apache CXF improper child policies enforcement issue.
Apache CXF versions 2.4.5 through 2.4.7, 2.5.1 through 2.5.3, and version 2.6.0 contain an issue that could result in weaker-than-expected security configurations.

These policies instruct the client to perform encryption or signing elements as directed by the policy, and a failure to apply the policies could lead to unsafe storage or transmission of sensitive information.
