<title>Go: User-assisted execution of arbitrary code</title>
<synopsis>A vulnerability in Go might allow remote attackers to execute
arbitrary commands during source code build.

<background>
<p>Go is an open source programming language that makes it easy to build
simple, reliable, and efficient software.
</p>
</background>
<description>
<p>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.
</p>
</description>
<impact type="high">
<p>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.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All Go users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/go-1.9.4"
</code>
</resolution>
