Security issues fixed:
* CVE-2017-9788: The value placeholder in [Proxy-]Authorization headers of
 type 'Digest' was not initialized or reset before or between successive
 key=value assignments by mod_auth_digest. Providing an initial key with
 no '=' assignment could reflect the stale value of uninitialized pool
 memory used by the prior request, leading to leakage of potentially
 confidential information, and a segfault in other cases resulting in
 denial of service. (bsc#1048576)
* CVE-2017-7679: mod_mime could have read one byte past the end of a
 buffer when sending a malicious Content-Type response header leading to
 information leak or crash. (bsc#1045060)
* CVE-2017-3169: mod_ssl may have dereferenced a NULL pointer when
 third-party modules call ap_hook_process_connection() during an HTTP
 request to an HTTPS port leading to crash. (bsc#1045062)
* CVE-2017-3167: Use of the ap_get_basic_auth_pw() by third-party modules
 outside of the authentication phase may have lead to authentication
 requirements being bypassed. (bsc#1045065)
Non-security issues fixed:
- Re-order cipher suites to keep exclusion list at the end. (bsc#1043484,
 bsc#1043607)
- Remove /usr/bin/http2 link only during apache2 package uninstall, not
 upgrade. (bsc#1041830)
- In gensslcert, use hostname when fqdn is too long. (bsc#1035829)");
