FreeBSD : Apache httpd -- several vulnerabilities (0c2db2aa-5584-11e7-9a7d-b499baebfeaf)

critical Nessus Plugin ID 100881


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote FreeBSD host is missing one or more security-related updates.


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.
