The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3194 advisory.

    The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server.

    Security Fix(es):

    * 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 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)

    * A use-after-free flaw was found in the way httpd handled invalid and previously unregistered HTTP     methods specified in the Limit directive used in an .htaccess file. A remote attacker could possibly use     this flaw to disclose portions of the server memory, or cause httpd child process to crash.
    (CVE-2017-9798)

    Red Hat would like to thank Hanno Bck for reporting CVE-2017-9798.
