"The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2017-2226:02 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.
