Buffer reference 1. Introduction In this tutorial, we’ll talk about buffers in computer programming. 2. Buffers Buffer is a generic term that means different things in different contexts. In general, we can say that a buffer is a tool that mitigates the effects of fluctuations in supply and...
A buffer is a continuous storage space in the operating system memory. A buffer overflow occurs when the data written by a program to the buffer exceeds the limit of the buffer and overwrites the adjacent memory space. Buffer overflow is a dangerous vuln
For example, a buffer for log-in credentials may be designed to expect username and password inputs of 8 bytes, so if a transaction involves an input of 10 bytes (that is, 2 bytes more than expected), the program may write the excess data past the buffer boundary. ...
Buffering, a mechanism that temporarily stores data, can enhance file handling performance. Reading or writing data in chunks from or to a buffer, rather than directly from or to a file, reduces the frequency of costly disk operations. This optimization is particularly beneficial when dealing with...
named pipes provide an alternative way of communicating between two processes instead of using an anonymous data buffer as regular pipes do. a named pipe creates a file handle which allows both the sender and receiver processes to access the same pipe simultaneously for communication purposes. this...
Here is a very simple example of a C program that is vulnerable to a stack overflow: main(intargc,char*argv[]) { func(argv[1]); }voidfunc(char*v){charbuffer[10]; strcpy(buffer, v); } Thestrcpyfunction in the above example copies the command argument into the destination buffer varia...
Techniques to exploit buffer overflow vulnerabilities vary based on the operating system (OS) and programming language. However, the goal is always to manipulate acomputer's memoryto subvert or control program execution. Buffer overflows are categorized according to the location of the buffer in the...

Buffer overflow is a software coding error that enables hackers to exploit vulnerabilities, steal data, and gain unauthorized access to corporate systems. Discover what is a buffer overflow attack and how Fortinet can mitigate and prevent overflow attack
Another possible name for a variable is a buffer, as it can be a temporary place to store data either only needed to act on other data or before it’s written to a file. When declaring variables in C, you need to explicitly state how much memory space needs to be allocated to the ...
