Red Hat Security Advisory

Synopsis: Important: httpd security update
Advisory ID: RHSA-2017:3193-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:3193
Issue date: 2017-11-13
CVE Names: CVE-2017-3167 CVE-2017-3169 CVE-2017-7668
CVE-2017-7679 CVE-2017-9788 CVE-2017-9798
=====================================================================

1. Summary:

An update for httpd is now available for Red Hat Enterprise Linux 7.2
Extended Update Support.

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.2) – noarch, x86_64
Red Hat Enterprise Linux Server EUS (v. 7.2) – noarch, ppc64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 7.2) – ppc64, ppc64le, s390x, x86_64

3. Description:

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 Böck for reporting CVE-2017-9798.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:
