Emmanuel Dreyfus discovered that third-party modules using the
ap_get_basic_auth_pw() function outside of the authentication phase may
lead to authentication requirements being bypassed. This update adds a new
ap_get_basic_auth_components() function for use by third-party modules.
Vasileios Panopoulos discovered that the Apache mod_ssl module may crash
when third-party modules call ap_hook_process_connection() during an HTTP
request to an HTTPS port. (CVE-2017-3169)
Javier Jiménez discovered that the Apache HTTP Server incorrectly handled
parsing certain requests. A remote attacker could possibly use this issue
to cause the Apache HTTP Server to crash, resulting in a denial of service.
ChenQin and Hanno Böck discovered that the Apache mod_mime module
incorrectly handled certain Content-Type response headers. A remote
attacker could possibly use this issue to cause the Apache HTTP Server to
crash, resulting in a denial of service. (CVE-2017-7679)
