Synopsis
========

Multiple vulnerabilities have been found in Go, the worst which could
lead to the execution of arbitrary code.

Background
==========

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

Affected packages
=================

Multiple vulnerabilities have been discovered in Go. Please review the
CVE identifiers referenced below for details.

Impact
======

A remote attacker could cause arbitrary code execution by passing
specially crafted Go packages the 'go get -u' command.

The remote attacker could also craft pathological inputs causing a CPU
based Denial of Service condition via the crypto/x509 package.

Workaround
