| Description: | Summary:
The remote host is missing an update for the Debian 'apache2' package(s) announced via the DSA-3896-1 advisory.
Vulnerability Insight:
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-2017-7659
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.
