[Jelle van der Waa]

Arch Linux Security Advisory ASA-201802-2
=========================================

Severity: High
Date    : 2018-02-09
CVE-ID  : CVE-2018-6574
Package : go
Type    : arbitrary code execution
Remote  : Yes
Link    : https://security.archlinux.org/AVG-606

Summary
=======

The package go before version 1.9.4-1 is vulnerable to arbitrary code
execution.

Resolution
==========

Upgrade to 1.9.4-1.

# pacman -Syu "go>=1.9.4-1"

The problem has been fixed upstream in version 1.9.4.

Workaround
==========

None.

Description
===========

Go before 1.8.7, Go 1.9.x before 1.9.4, and Go 1.10 pre-releases before
Go 1.10rc2 allow "go get" remote command execution during source code
build, by leveraging the gcc or clang plugin feature, because -fplugin=
and -plugin= arguments were not blocked.

Impact
======

A remote attacker is able to trick the “go get” command into executing
arbitrary code by passing a maliciously-crafted flag to the gcc or
clang backends.
