Versions of the puppetlabs-apache module prior to 1.11.1 and 2.1.0 make it very easy to accidentally misconfigure TLS trust. If you specify the `ssl_ca` parameter but do not specify the `ssl_certs_dir` parameter, a default will be provided for the `ssl_certs_dir` that will trust certificates from any of the system-trusted certificate authorities. This did not affect FreeBSD.Show less

An error was found in the X-Pack Security TLS trust manager for versions 5.0.0 to 5.5.1. If reloading the trust material fails the trust manager will be replaced with an instance that trusts all certificates. This could allow any node using any certificate to join a cluster. The proper behavior in this instance is for the TLS trust manager to deny all certificates.Show less
