3. Description:
The httpd packages provide the Apache HTTP Server, a powerful, efficient,
and extensible web server.
Security Fix(es):
* It was discovered that httpd used the value of the Proxy header from HTTP
requests to initialize the HTTP_PROXY environment variable for CGI scripts,
which in turn was incorrectly used by certain HTTP client implementations
to configure the proxy for outgoing HTTP requests. A remote attacker could
possibly use this flaw to redirect HTTP requests performed by a CGI script
to an attacker-controlled proxy via a malicious HTTP request.
(CVE-2016-5387)
Note: After this update, httpd will no longer pass the value of the Proxy
request header to scripts via the HTTP_PROXY environment variable.
* A flaw was found in the way httpd performed client authentication using
X.509 client certificates. When the HTTP/2 protocol was enabled, a remote
attacker could use this flaw to access resources protected by certificate
authentication without providing a valid client certificate.
(CVE-2016-4979)
Red Hat would like to thank Scott Geary (VendHQ) for reporting
CVE-2016-5387 and Apache Software Foundation for reporting CVE-2016-4979.
Upstream acknowledges Erki Aring (Liewenthal Electronics Ltd) as the
original reporter of CVE-2016-4979.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing the updated packages, the httpd daemon will be restarted
automatically.
5. Bugs fixed (https://bugzilla.redhat.com/):
1352476 - CVE-2016-4979 httpd: X509 client certificate authentication bypass using HTTP/2
1353755 - CVE-2016-5387 Apache HTTPD: sets environmental variable based on user supplied Proxy request header

Red Hat Security Advisory
Synopsis: Important: httpd security and bug fix update
Advisory ID: RHSA-2016:1422-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2016:1422
Issue date: 2016-07-18
CVE Names: CVE-2016-5387
=====================================================================
1. Summary:
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.

Red Hat Enterprise Linux Client Optional (v. 7) - noarch, x86_64
Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch, x86_64
Red Hat Enterprise Linux Server (v. 7) - noarch, 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 httpd used the value of the Proxy header from HTTP
requests to initialize the HTTP_PROXY environment variable for CGI scripts,
which in turn was incorrectly used by certain HTTP client implementations
to configure the proxy for outgoing HTTP requests. A remote attacker could
possibly use this flaw to redirect HTTP requests performed by a CGI script
to an attacker-controlled proxy via a malicious HTTP request.
(CVE-2016-5387)
Note: After this update, httpd will no longer pass the value of the Proxy
request header to scripts via the HTTP_PROXY environment variable.
Red Hat would like to thank Scott Geary (VendHQ) for reporting this issue.
Bug Fix(es):
* In a caching proxy configuration, the mod_cache module would treat
content as stale if the Expires header changed when refreshing a cached
response. As a consequence, an origin server returning content without a
fixed Expires header would not be treated as cacheable. The mod_cache
module has been fixed to ignore changes in the Expires header when
refreshing content. As a result, such content is now cacheable, improving
performance and reducing load at the origin server. (BZ#1347648)
* The HTTP status code 451 "Unavailable For Legal Reasons" was not usable
in the httpd configuration. As a consequence, modules such as mod_rewrite
could not be configured to return a 451 error if required for legal
purposes. The 451 status code has been added to the list of available error
codes, and modules can now be configured to return a 451 error if required.
(BZ#1353269)
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing the updated packages, the httpd daemon will be restarted
automatically.
5. Bugs fixed (https://bugzilla.redhat.com/):
1347648 - Apache can not cache content if Expires header is modified
1353269 - Support sending http 451 status code from RewriteRule
1353755 - CVE-2016-5387 Apache HTTPD: sets environmental variable based on user supplied Proxy request header
