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
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

  1  dev-lang/go                  < 1.10.7                  >= 1.10.7 

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

Resolution
=========
