Detail

Problem Description:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Server Optional (v. 7) - noarch, x86_64

3. Description:

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 issue.
