Synopsis
========
A vulnerability in Go might allow remote attackers to execute arbitrary
commands during source code build.

Background
==========
Go is an open source programming language that makes it easy to build
simple, reliable, and efficient software.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-lang/go < 1.9.4 >= 1.9.4

Description
===========
A command injection flaw was discovered in the source code build phase
because of the "go get" command, which does not block -fplugin= and
-plugin arguments.

Impact
======
A remote attacker could entice a user to process a repository
containing maliciously-crafted build instructions using "go get",
resulting in the execution of arbitrary code with the privileges of the
process.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Go users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/go-1.9.4"

References
==========
[ 1 ] CVE-2018-6574
