Too Long; Didn't Read
When we enter data in a buffer more than its capacity the data overflows to adjacent memory location causing program to crash. An attacker or hacker can use this vulnerability to exploit the system. Stack Overflow is an old vulnerability in the C or C++ languages, because in these languages we can use pointer freely. The code was compiled and run on Ubuntu 18.04 using a simple C program to understand this vulnerability. It doesn’t allow checking the size of the data being entered.
