A common stack overflow exploit is to change the value of RETADDR and store the address of the attack code injected into the stack or the addresses of some privileged system functions in the code area to RETADDR. If the value of RETADDR is changed, after the function is called, the program...
What is a Buffer Overflow Attack Attackers exploit buffer overflow issues by overwriting the memory of an application. This changes the execution path of the program, triggering a response that damages files or exposes private information. For example, an attacker may introduce extra code, sending ...
The stack-based buffer overflow occurs when an attacker explicitly aims his input toward the stack section of the memory. This is the most common type of buffer overflow attack and the easier one. The excess input overruns the stack memory and hands the program’s control to the attacker. ...
Stack overflow attack- This is the most common type of buffer overflow attack and involves overflowing a buffer on the call stack*. Heap overflow attack- This type of attack targets data in the open memory pool known as the heap*.

Buffer overflows are one of the most common software weaknesses present today. They can happen inadvertently or when a cyber attacker causes it. Either way, it opens opportunities for attack. One real-life example of a buffer overflow attack is the 1988 Morris Worm. The Morris Worm was acomp...
Stack-based buffer overflow or stack buffer overrun attack The stack holds data in a last-in, first-out structure. It is a continuous space in memory used to organize data associated with function calls, including function parameters, function local variables and management information, such as fr...
A cyber attack is an online attack targeting an enterprise or individual for the purpose of disrupting, disabling, destroying, or maliciously controlling their computing infrastructure; destroying the integrity of their data; or stealing controlled information. ...
Stack smashing is a type of vulnerability that occurs when a hacker exploits a flaw in a program's memory allocation, causing the program to crash or execute arbitrary code. In this article, we will explore what stack smashing is, how it works, and what
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
