Buffer overflow attack

 A buffer overflow attack is a type of computer security vulnerability in which a program writes more data to a buffer, or temporary storage area, than it was designed to hold. This extra data can overflow into adjacent memory locations, potentially overwriting important data or instructions and causing the program to behave in unexpected or malicious ways.

Attackers can exploit buffer overflow vulnerabilities to take control of a program, inject malicious code, or even execute arbitrary commands on a target system. This type of attack can be particularly dangerous because it can allow an attacker to gain remote access to a system without any user interaction.

Buffer overflow attacks can be prevented by properly validating user input, checking buffer sizes, and using secure programming practices such as bounds checking and input validation. It is also important to keep software up to date with security patches and updates to minimize the risk of known vulnerabilities being exploited.
