An overflow attack occurs when an attacker exploits a vulnerability in a program by inputting more data than the buffer can handle, leading to data corruption or the execution of malicious code.
• Used by attackers to execute arbitrary code by overflowing buffers in memory, such as in buffer overflow attacks.• Employed to crash systems or gain unauthorized access by exploiting poorly written software.
Attackers input more data than a program's memory buffer can handle, which can cause the system to overwrite adjacent memory, potentially leading to arbitrary code execution.
Overflow attacks can lead to system crashes, unauthorized access, or the execution of malicious code, compromising system integrity.
Developers can prevent overflow attacks by using proper input validation, bounds checking, and secure coding practices to handle memory buffers.
