A buffer is a continuous storage space in the operating system memory. A buffer overflow occurs when the data written by a program to the buffer exceeds the limit of the buffer and overwrites the adjacent memory space. Buffer overflow is a dangerous vuln
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 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

Buffer overflows are one of the worst bugs that can be exploited by an attacker mostly because it is very hard to find and fix, especially if the software consists of millions of lines of code. Even the fixes for these bugs are quite complicated and error-prone. That is why it is real...
1] Stack-based buffer overflow attack 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 ...
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...
What is Buffer Overflow Buffers are memory storage regions that temporarily hold data while it is being transferred from one location to another. A buffer overflow (or buffer overrun) occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program att...
A buffer overflow vulnerability occurs when you give a program too much data. The excess data corrupts nearby space in memory and may alter other data. As a result, the program might report an error or behave differently.
