Oracle Linux 7 : golang (ELSA-2016-1538) (httpoxy)

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

Synopsis :

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

Description :

From Red Hat Security Advisory 2016:1538 :

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

Red Hat Product Security has rated this update as having a security
impact of Moderate. 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 golang packages provide the Go programming language compiler.

The following packages have been upgraded to a newer upstream version:
golang (1.6.3). (BZ#1346331)

Security Fix(es) :

* An input-validation flaw was discovered in the Go programming
language built in CGI implementation, which set the environment
variable 'HTTP_PROXY' using the incoming 'Proxy' HTTP-request header.
The environment variable 'HTTP_PROXY' is used by numerous web clients,
including Go's net/http package, to specify a proxy server to use for
HTTP and, in some cases, HTTPS requests. This meant that when a
CGI-based web application ran, an attacker could specify a proxy
server which the application then used for subsequent outgoing
requests, allowing a man-in-the-middle attack. (CVE-2016-5386)

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