I decided to get a bit more into Linux exploitation, so I thought it would be nice if I document this as agood friend once said " you think you understand something until you try to teach it ". This is my first try at writing papers. This paper is my understanding of the subject....

buffer overflow exploit, as it allows us to see what is going on inside the application during the crash that allows a buffer overflow to occur. This information allows us to structure a buffer to be sent to the application in a fashion that allows us to take control of that programs ...
That’s it for Part 2 in this series. Hopefully you now understand the basics of a stack-based buffer overflow including why it’s a problem, how it can manifest itself in a software application, and how to exploit it to force arbitrary code execution. ...
In the next section, I’ll provide an introduction to control flow attacks with particular focus on stack buffer overflows. I’ll discuss how they occur and how an attacker can exploit them. Then I’ll look in detail at how /GS impacts your code and the degree to which it can mitigate...

start the course by explaining the basics of stack buffer overflows and exploit writing, but this is most certainly not “your average” entry level course. In fact, this is a true bootcamp and one of the finest and most advanced courses you will find on Win32 stack based exploit ...
A stack-based buffer overflow was found in libresolv in the code which performs dual A/AAAA DNS queries. A remote attacker could create specially crafted DNS responses which could cause libresolv to crash or potentially execute code with the permissions of the user running the library. The buffer...
