===================================================================== Red Hat Security Advisory
Synopsis: Important: httpd security update Advisory ID: RHSA-2017:3195-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:3195 Issue date: 2017-11-13 CVE Names: CVE-2017-3167 CVE-2017-3169 CVE-2017-7679 CVE-2017-9788 CVE-2017-9798 =====================================================================
1. Summary:
An update for httpd is now available for Red Hat Enterprise Linux 6.7 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 HPC Node EUS (v. 6.7) - x86_64 Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) - noarch, x86_64 Red Hat Enterprise Linux Server EUS (v. 6.7) - i386, noarch, ppc64, 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 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.
