(FIFO) data structure used to store data that is required for a long time during program running. When the heap overflows, even if the program does not stop execution immediately, the program may be unstable or even crash. In malicious attacks, attackers may use heap buffer overflow to ...
A stack overflow is a type ofbuffer overflowerror that occurs when a computer program tries to use more memory space in the call stack than has been allocated to that stack. The call stack, also referred to as the stack segment, is a fixed-sizedbufferthat stores local function variables and...
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
There are two primary types of buffer overflow vulnerabilities:stack overflowandheap overflow. In the case of stack buffer overflows, the issue applies to the stack, which is the memory space used by the operating system primarily to store local variables and function return addresses. The data ...
Stack overflow is a programming error in which an attempt to write data to a particular block of memory fails because there is no space left in the block. This type of error happens in the same way as buffer overflows, heap overflows, and stack buffer overflows. The difference between ...
Heap-based buffer overflow attack The heap is a memory structure used to managedynamic memory. Programmers often use the heap to allocate memory whose size is unknown at compile time, where the amount of memory required is too large to fit on the stack or the memory is intended to be used...
How do I check whether an application is a system application? How do I capture the crash stack and implement the crash callback? How do I analyze the CPU usage of an application in running? How do I quickly read and analyze heap dump (memory), application memory usage, and maximum...

Heap overflows: A form of buffer overflow that happens when a chunk of memory is allocated to the heap and data is written to this memory without any bound checking being done on the data. Stack overflows: A type of buffer overflow that causes a program to write more data to a buffer...
