A stack buffer is a type of buffer or temporary location created within a computer’s memory for storing and retrieving data from the stack. It enables the storage of data elements within the stack, which can later be accessed programmatically by the program’s stack function or any other fun...
and software exceptions. It thus prevents an attacker from being able to make use of the SEH overwrite exploitation technique. At a functional level, an SEH overwrite is achieved using a stack-based buffer overflow to overwrite an exception registration record, stored on a thread’s stack. ...
A buffer overflow attack is a commoncyberattackthat exploits buffer overflow vulnerabilities to gain control of a computer system. It takes place when a program writes data outside the bounds of a buffer, overwriting portions of memory connected to the buffer space. Cybercriminals exploit buffer o...
Buffering is the practice of preloading and storing a portion of a media file in the buffer or temporary memory of a device. This process enables video, audio, gaming, or other media files to be played smoothly and without jitter or stuttering. Having an advanced supply of video frames, aud...
New Driver Stack for USB 3.0 Devices Windows 8 provides a new USB driver stack to support USB 3.0 devices. The new stack includes drivers that are loaded by Windows when a USB 3.0 device is attached to an xHCI host controller. The new drivers are based on Kernel Mode Driver Framework (KM...
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...
In the early stage, routers limit the maximum size of packets. Many operating systems specify 64 KB as the maximum size of an ICMP message in the TCP/IP protocol stack. After the header of an ICMP message is read, a buffer is generated for the payload based on the information contained ...
The DRIVER_OVERRAN_STACK_BUFFER error is a BSOD (Blue Screen of Death) stop error caused by a faulty device driver in Windows. It occurs when the driver writes data outside its defined memory address. However, multiple other reasons—such as file corruption, disk errors, and malwar...
Estimated memory usage of a single connection (single_thread_memory) = thread_stack (256 KB) + binlog_cache_size (32 KB) + join_buffer_size (256 KB) + sort_buffer_size (256 KB) + read_buffer_size (128 KB) + read_rnd_buffer_size (256 KB) ≈ 1 MB The following table lists the...
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
