Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for httpd is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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)
