Debian LTS Advisory ([SECURITY] [DLA 1009-1] apache2 security update)

Several vulnerabilities have been found in the Apache HTTPD server. 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-2017-7668 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.
