http://security.gentoo.org/

Severity:	high
Title:	Go: User-assisted execution of arbitrary code
Date:	03/07/2018
Bugs:	#647250
ID:	201803-03

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	Architecture(s)
dev-lang/go	< 1.9.4	>= 1.9.4	All supported architectures

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"
