"This update includes the latest upstream release, 

**httpd 2.4.34**, with multiple bug fixes and enhancements. See
http://www.apache.org/dist/httpd/CHANGES_2.4.34 for more information
on the changes in this version.

A security vulnerability is addressed in this update :

  - `mod_md`: DoS via Coredumps on specially crafted
    requests (CVE-2018-8011) The following changes are also
    included in this update :

  - The post-transaction scriptlet to restart
    `httpd.service` no longer blocks waiting for the restart
    to complete.

  - `mod_ssl` now supports loading private keys (and
    associated certificates) from a PKCS#11 provider. Use a
    `pkcs11:` URI in the `SSLCertificateKeyFile` (and
    optionally `SSLCertificateFile`) directive(s).

  - An example Lua-based `server-status.conf` is packaged in
    the docdir 

  - `httpd` now Obsoletes `mod_proxy_uwsgi` (RHBZ#1599113)

  - `mod_systemd` now logs listening ports at startup

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
