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
This type of buffer overflow attack is aimed at another part of a system memory called Heap. This means an attack overwrites data at the heap side of the buffer. Heap-based buffer overflow attack is more brutal compared to the former. ...
Techniques to exploit buffer overflow vulnerabilities vary based on the operating system (OS) and programming language. However, the goal is always to manipulate acomputer's memoryto subvert or control program execution. Buffer overflows are categorized according to the location of the buffer in the...
Heap-Based Buffer Overflow: The program heap is used to dynamically allocate memory to variables whose size is not defined when the program compiles. By exploiting a buffer overflow vulnerability and flooding the system heap, an attacker can overwrite critical application data. Format String Attacks...
Stack-based buffer overflowsare more common, and leverage stack memory that only exists during the execution time of a function. Heap-based attacksare harder to carry out and involve flooding the memory space allocated for a program beyond memory used for current runtime operations. ...
Heap-based overflows target the heap, a region of memory used for dynamic memory allocation. To exploit a buffer overflow, a hacker needs to find a vulnerability in a program that allows them to write data to a buffer without bounds checking. Once they’ve found such a vulnerability, they...
How do I query the allocated heap memory size and free heap memory size of an application? How do I obtain system logs when an application fault occurs? How do I use the hdc command to send a local file to a remote device? How do I check whether an application is a system appli...
Is it configurable? Why is private displayed in HiLog information when the format parameter %d or %s is specified? What should I do if the hilog.debug log cannot be printed? How do I control the log output level based on the environment? How do I locate application performance ...

Unlike stack-based overflow, which targets the stack, heap-based attacks target dynamically allocated memory on the heap. This happens when a buffer in the heap - which is a region of a computer's memory space used for dynamic memory allocation - is overflowed. The attacker can overwrite data...
