标题:Intel和ARM CPU芯片信息泄露漏洞 (CVE-2017-5715)Description:ARM Cortex-R7等都是英国ARM公司的产品。ARM Cortex-R7是一款中央处理器（CPU）。Cortex-R8是一款中央处理器（CPU）。Intel Xeon CPU E5-1650等都是美国英特尔（Intel）公司的产品。Xeon CPU E5-1650是一款中央处理器（CPU）。 Intel和ARM CPU芯片中存在信息泄露漏洞，该漏洞源于处理器数据边界机制中存在缺陷。本地攻击者可通过滥用‘错误推测执行’利用该漏洞读取内存信息。以下产品和版本受到影响：ARM Cortex-R7；Cor
Description
Spectre exploit
介绍
# Spectre attack
Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre.
This exploit check your Linux (x64 only) for the spectre vulnerability.
# Compile
Just run `make` to compile the source code.
# Run
Execute the exploit
```
taskset -c 1 ./exploit
[+] Testing for Spectre
[+] Dumping memory from 0xffffffffffdfeea8 to 0xffffffffffdfeec2
[+] Dumped bytes match the expected value
[+] System vulnerable to spectre
```
# Authors
Spectre was independently discovered and reported by two people:
* Jann Horn (Google Project Zero).
* Paul Kocher in collaboration with, in alphabetical order, Daniel Genkin (University of Pennsylvania and University of Maryland), Mike Hamburg (Rambus), Moritz Lipp (Graz University of Technology), and Yuval Yarom (University of Adelaide and Data61).
