Oracle Linux 5 / 6 : httpd (ELSA-2016-1421) (httpoxy)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2016:1421 :

An update for httpd is now available for Red Hat Enterprise Linux 5
and Red Hat Enterprise Linux 6.

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 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

Red Hat would like to thank Scott Geary (VendHQ) for reporting this
