问题描述

我想知道悬挂指针会以什么样的方式影响使用C ++开发的应用程序的安全性。通过悬空指针创建的漏洞是什么？b
$ b他们如何被黑客利用

？

I would like to know in what manner dangling pointers affect the
security of a application developed using C++.What are the loopholes
that are created by dangling pointers and how they could be exploited
by hackers?.

你的方式很简单！

首先，黑客做了什么？他们通过

互联网访问计算机和网络并做你不希望他们做的事情。


你如何阻止它们？首先不要给他们这个能力！

听起来很简单？那么为什么人们会被黑客攻击？主要是因为微软是傻瓜b
;它可以实现文件共享等功能。和打印机共享通过

互联网协议TCP / IP。黑客利用已明确给予他们* b $ b的能力*。

现在，悬空指针：


int * pChocolate = new int;


删除pChocolate;


* pChocolate = 5;


那'这是一个悬垂的指针，正如你所看到的，它与黑客和/或黑客无关。

希望有所帮助。 br />

You are way way wayyyyyyyy off!
First, what do hackers do? They access computers and networks via the
Internet and do things that you don''t want them to do.

How do you stop them? Don''t give them the ability in the first place!
Sounds simple? So why do people get "hacked"? Mainly because Microsoft is
stupid; it enables things like "file sharing" and "printer sharing" via the
internet protocol TCP/IP. Hackers exploit the ability *that has explicitly
been given to them*.
Now, dangling pointers:

int* pChocolate = new int;

delete pChocolate;

*pChocolate = 5;

That''s what a dangling pointer is, and as you can see, it has nothing at all
whatsoever to do with hacking and/or hackers.
Hope that helps.

实际上，他们不是。这就是媒体从黑客这个词中得到的结果。黑客实际上只是一个擅长编程并且喜欢它的程序员。

Actually, they don''t. That''s what the media made out of the word
"hacker". A hacker is actually just a programmer who is good at
programming and who likes it.
