Apache httpd -- several vulnerabilities

The Apache httpd project reports:

• ap_get_basic_auth_pw() Authentication Bypass (CVE-2017-3167):
  Use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.
• mod_ssl Null Pointer Dereference (CVE-2017-3169):
  mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.
• mod_http2 Null Pointer Dereference (CVE-2017-7659):
  A maliciously constructed HTTP/2 request could cause mod_http2 to dereference a NULL pointer and crash the server process.
• ap_find_token() Buffer Overread (CVE-2017-7668):
  The HTTP strict parsing changes added in 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value.
• mod_mime Buffer Overread (CVE-2017-7679):
  mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header.
