Memory Allocators Galore

Allocators are strange creatures in the C++ bestiary, but they are key to understanding the language internals. Are you fascinated by memory allocation in the lower level? Well you've come to the right place!

This projects encompasses my efforts around creating some of the most popular memory allocators and it will serve as a reference point henceforth:

1. Pre-C++11 default allocator (DefaultAllocator & TrackingAllocator projects)
2. C++11 compatible allocator replacements (Allocators & AlignedAllocator projects)
3. Linear (aka Arena) allocator (LinearAllocatorproject)
   
4. Stack Allocator (StackAllocator &...

Buffer Overflow Tutorial

This is a Buffer overflow tutorial using linux Ubuntu and C programming. There is full explanation and code in Greek only at the moment in “Nikos_Lazaridis_M1485_Project#2_ΥΣ13_ΕΑΡΙΝΟ_2017.pdf”. I may be motivated to translate this in English if I see any traffic.

! During Buffer Overflow:
The ultimate goal of a Buffer overflow attack is replacing the return address of a vulnerable/unsecure function with another one of our choosing. The latter function will have "ASCII shellcode" placed into it, which will execute the attacker's desired code (WE are the attacker here); the sky's the limit with what the attacker can do (more like the imagination of the attacker). “Buffer Overflow” occurs the moment where a single byte is written in the return address...

Windows Leak Checker

Simply integrate the files to your own program and test if you have any memory leaks.

You don't have to reference this code in your own code files. It will do everything on its own, so long as you add the files to your program and compile them.

Note that it works only in debug mode.

This is essentially a barebones alternative to the free and open source "Visual Leak Detector".

I used Windows and Microsoft Visual Studio to build the project.
