CVE-2017-3167 
Emmanuel Dreyfus reported that the use of ap_get_basic_auth_pw() by
third-party modules outside of the authentication phase may lead to
authentication requirements being bypassed.

CVE-2017-3169 
Vasileios Panopoulos of AdNovum Informatik AG discovered that
mod_ssl may dereference a NULL pointer when third-party modules call
ap_hook_process_connection() during an HTTP request to an HTTPS port
leading to a denial of service.

CVE-2017-7659 
Robert Swiecki reported that a specially crafted HTTP/2 request
could cause mod_http2 to dereference a NULL pointer and crash the
server process.

CVE-2017-7668 
Javier Jimenez reported that the HTTP strict parsing contains a
flaw leading to a buffer overread in ap_find_token(). A remote
attacker can take advantage of this flaw by carefully crafting a
sequence of request headers to cause a segmentation fault, or to
force ap_find_token() to return an incorrect value.

CVE-2017-7679 
ChenQin and Hanno Boeck reported that mod_mime can read one byte
past the end of a buffer when sending a malicious Content-Type
response header.");
