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. ...

A buffer, or data buffer, is an area of physical memory storage used to temporarily store data while it is being moved from one place to another. These buffers typically live in RAM memory. Computers frequently use buffers to help improve performance; most modern hard drives take advantage of...
How can i prepare a buffer solution?Buffer Solutions:Buffer solutions are used to maintain the constant pH and resist any pH changes in a wide number of solutions. Buffer is prepared by mixing weak acid with its conjugate base. It works on the principle of the common ion effect....
an input buffer is a temporary storage area used in computing to hold data being received from an input device, such as a keyboard or a mouse. it allows the system to receive and process input at its own pace, rather than being dependent on the speed at which the input is provided. ...
Buffering is the practice of preloading and storing a portion of a media file in the buffer or temporary memory of a device. This process enables video, audio, gaming, or other media files to be played smoothly and without jitter or stuttering. Having an advanced supply of video frames, aud...

What is a buffer overflow attack and how does one work? Exploiting a buffer overflow allows an attacker to control or crash a process or to modify its internal variables. Buffer overflow always ranks high in the Common Weakness Enumeration (CWE) andSANS Top 25 Most Dangerous Software Errors. ...
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...
