Stack Overflow in windows-principles
Let's take a look at the programs in windows. We aim to study how to exploit the stack overflow vulnerability of windows programs. Let's start from scratch.

Stack objects are automatically generated when appropriate and destroyed when appropriate.
Program The creation speed of stack objects is usually faster than that of heap objects, because operator new will be called when heap objects are allocated, and operator new will use some memory space to search.
Algorithm The search process may be time-consuming, and it is not so troublesome to generate
Javascript: traversing the prototype chain, calling stack, and scope chain
In JavaScript, there are three common chain structures: prototype chain, call stack (Call StackScope chain. This article does not want to talk about the basic knowledge of these concepts, but rather shows how to traverse the three chain structures to deepen understanding. Traverse prototype chain

Cars numbered 1, 2, ..., n are on the "on the", and it is desired to rearrange (permute) the cars as they leave on t He right-hand track. A car "is" on the spur (stack) can are left there or sent on their way down the right track, but it can never being sent back to the incoming track. For example, if n=3, and we have the "Ca

We need to create a hanker program through stack overflow. After the foo program is executed, the Goto program is sent to the hacker program without sound information. After the hanker is executed, return to the place where foo is called accurately.
First, you need to clarify the following points.
1. the following code usually starts and ends with a function (except main:
Pushl % EBP
2. During Foo call bar, the EIP is first pushed to the

All object instances are allocated with memory on the Java stack. The heap size is adjusted by-Xmx and-Xms, as shown in the following sample:

In this chapter we will discuss the stack.1. FeaturesAdvanced, when an element is pressed into the stack, he will be at the bottom of the stack, and then, another pressure in, cover the original elements above, the original elements want to go out, only the above elements to the top of the stack before the opportunity.
a type, such as:char ch; float x; int a,b,c;CH is a character type and is allocated to 2 bytes of memory. Different types of variables have different bytes allocated in memory, and they are stored in different ways.Therefore, it is necessary to determine the type of the variable before assigning a value, and determine the type of the variable, that is, determine the size of the memory space to allocate the data, and how the data will be stored in memory.Iv. Storage of Java data types in memory

One: The mathematical nature of the stackWhen n numbered elements are stacked in a certain order, and can be stacked at any time, the number of numbers ordered by the number of elements n is exactly the sum of the Catalan functions, i.e.Two: Topic One:Try to put 1,2,3,4,5,6, six digits into the stack, then there are several ways out of the stack?

The growth direction of the stack from the most essential understanding is whether the stack is in the stack direction from high address to address or low address to high address.
growth from a high address to a low address is generally called downward growth, also known as reverse growth.
