标题：
Docker 操作系统命令注入漏洞
(CVE-2019-5736)
描述：Docker是美国Docker公司的一款开源的应用容器引擎。该产品支持在Linux系统上创建一个容器（轻量级虚拟机）并部署和运行应用程序，以及通过配置文件实现应用程序的自动化安装、部署和升级。 Docker 18.09.2之前版本和其他产品中的runc 1.0-rc6及之前版本中存在安全漏洞，该漏洞源于程序没有正确地处理文件描述符。攻击者可利用该漏洞覆盖主机runc的二进制文件并以root权限执行命令。
描述
Exploit for the CVE-2019-5736 runc vulnerability
介绍
# cve-2019-5736-exp
This is a proof-of-concept (PoC) exploit for the CVE-2019-5736 vulnerability in
runc, the runtime used in Docker.
## Disclaimer
I undertook this project as an exercise, for educational reasons and for fun.
It should go without saying that I do not support unethical and/or illegal
misuse of this code.
## Description
The vulnerability was discovered by [Adam Iwaniuk] and [Borys Popławski] and
described in this [blog post][ds]. Thanks for the great research!

## Usage
To build a malicious container:
```
docker build .
```
Running this container will cause the runc binary to be overwritten with the
contents of the `payload` file, i.e.
```
docker run <image_id>
```
Next time runc is executed (e.g when a different container is run), the host
will execute your payload.
