The remote host is running a version of FireEye Operating System (FEOS) that is affected by multiple vulnerabilities. See vendor release notes for details.

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-2175:02 advisory.

    * It was discovered that the httpd's mod_auth_digest module did not properly     initialize memory before using it when processing certain headers related to     digest authentication. A remote attacker could possibly use this flaw to     disclose potentially sensitive information or cause httpd child process to crash     by sending specially crafted requests to a server. (CVE-2017-9788)
      * It was discovered that the use of httpd's ap_get_basic_auth_pw() API     function outside of the authentication phase could lead to authentication     bypass. A remote attacker could possibly use this flaw to bypass required     authentication if the API was used incorrectly by one of the modules used by     httpd. (CVE-2017-3167)
      * A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A     remote attacker could use this flaw to cause an httpd child process to crash if     another module used by httpd called a certain API function during the processing     of an HTTPS request. (CVE-2017-3169)
      * A NULL pointer dereference flaw was found in the mod_http2 module of httpd.
    A remote attacker could use this flaw to cause httpd child process to crash via     a specially crafted HTTP/2 request. (CVE-2017-7659)
      * A buffer over-read flaw was found in the httpd's ap_find_token() function. A     remote attacker could use this flaw to cause httpd child process to crash via a     specially crafted HTTP request. (CVE-2017-7668)
      * A buffer over-read flaw was found in the httpd's mod_mime module. A user     permitted to modify httpd's MIME configuration could use this flaw to cause     httpd child process to crash. (CVE-2017-7679)     CVE-2017-3167     In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of     the ap_get_basic_auth_pw() by third-party modules outside of the     authentication phase may lead to authentication requirements being     bypassed.
    CVE-2017-3169     In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl     may dereference a NULL pointer when third-party modules call     ap_hook_process_connection() during an HTTP request to an HTTPS port.
    CVE-2017-7659     A maliciously constructed HTTP/2 request could cause mod_http2 2.4.24,     2.4.25 to dereference a NULL pointer and crash the server process.
    CVE-2017-7668     The HTTP strict parsing changes added in Apache httpd 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.
    CVE-2017-7679     In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_mime     can read one byte past the end of a buffer when sending a malicious     Content-Type response header.
    CVE-2017-9788     In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value     placeholder in [Proxy-]Authorization headers of type 'Digest' was not     initialized or reset before or between successive key=value     assignments by mod_auth_digest. Providing an initial key with no '='     assignment could reflect the stale value of uninitialized pool memory     used by the prior request, leading to leakage of potentially     confidential information, and a segfault in other cases resulting in     denial of service.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

ap_find_token() buffer overread :

A buffer over-read flaw was found in the httpd's ap_find_token() function. A remote attacker could use this flaw to cause httpd child process to crash via a specially crafted HTTP request. (CVE-2017-7668 )

Apache HTTP Request Parsing Whitespace Defects :

It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by the HTTP protocol specification to appear unencoded in HTTP request headers. If httpd was used in conjunction with a proxy or backend server that interpreted those characters differently, a remote attacker could possibly use this flaw to inject data into HTTP responses, resulting in proxy cache poisoning. (CVE-2016-8743)

ap_get_basic_auth_pw() authentication bypass :

It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd. (CVE-2017-3167)

mod_mime buffer overread :

A buffer over-read flaw was found in the httpd's mod_mime module. A user permitted to modify httpd's MIME configuration could use this flaw to cause httpd child process to crash. (CVE-2017-7679)

mod_http2 NULL pointer dereference :

A NULL pointer dereference flaw was found in the mod_http2 module of httpd. A remote attacker could use this flaw to cause httpd child process to crash via a specially crafted HTTP/2 request.
(CVE-2017-7659)

mod_ssl NULL pointer dereference :

A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause a httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request. (CVE-2017-3169)

The remote host is affected by the vulnerability described in GLSA-201710-32 (Apache: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Apache. Please review       the referenced CVE identifiers for details.
  Impact :

    The Optionsbleed vulnerability can leak arbitrary memory from the server       process that may contain secrets.  Additionally attackers may cause a       Denial of Service condition, bypass authentication, or cause information       loss.
  Workaround :

    There is no known workaround at this time.

This update for apache2 fixes several issues. These security issues were fixed :

  - CVE-2017-9789: When under stress (closing many     connections) the HTTP/2 handling code would sometimes     access memory after it has been freed, resulting in     potentially erratic behaviour (bsc#1048575).

  - CVE-2017-7659: A maliciously constructed HTTP/2 request     could cause mod_http2 to dereference a NULL pointer and     crash the server process (bsc#1045160).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
