   An update that solves four vulnerabilities and has four
   fixes is now available.

Description:


   This update for apache2 provides the following fixes:

   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)
