is an area that surrounds one or more map features. The size of a buffer can be a specified width (e.g., 5 miles from a store, 1000 feet from a school, 1km from a highway) or variable based on some attribute (e.g., contains 10,000 households). ...
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. ...
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
A classical example is a video streaming service. Here, the video player at the client usually sets the buffer size as a function of the network characteristics. It prefetches media content from the server across the medium and stores it in the buffer so that the end user experiences no jit...

exploit buffer overflow vulnerabilities to damage objects, including ARG (actual parameter when the function is called), RETADDR (address of the next operation instruction in the memory), EBP (stack frame status value before the function is called), and LOCVAR (local variable in this function)....
A buffer underrun error, also known as a buffer underflow, is a type of error that occurs in the buffer system that communicates between two processes or devices. With a buffer underrun, the buffer is empty and one device or process needs to stop while the other attempts to feed more ...
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...
