In this tutorial, I will be going to tell you about buffer overflow.cWhat is Buffer Overflow? I will show you a buffer overflow attack example. So, Let's start what is a buffer overflow?

A buffer overflow occurs whenever a program or a process tries to put more data into a fixed length block of memory or than the buffer is allocated to hold.Buffers are made to hold a specific or defined amount of data, the unnecessary data can overwrite other data values in memory unless the program includes discard data when too much is data is being sent to memory. If an attacker is able to exploit the buffer overflow.He will be able to crash the program process or can modify its internal values. Buffer overflow is a most common vulnerability. It ranks high in top 25 Most Dangerous Software errors and is specified as CWE-120 under the common weakness Enumeration dictionary of weakness types.
