"From Red Hat Security Advisory 2017:1859 :

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 later upstream version:
golang (1.8.3). (BZ#1414500)

Security Fix(es) :

* A carry propagation flaw was found in the implementation of the
P-256 elliptic curve in golang. An attacker could possibly use this
flaw to extract private keys when static ECDH was used.
(CVE-2017-8932)

Additional Changes :

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.4 Release Notes linked from the References section."
