In software, a stack buffer overflow or stack buffer overrun occurs when a program writes to a memory address on the program's call stack outside of the intended data structure, which is usually a fixed-length buffer.Stack buffer overflow bugs are caused when a program writes more data to a buffer located on the stack than what is actually allocated for that buffer. This almost always results in corruption of adjacent data on the stack, and in cases where the overflow was triggered by mistake, will often cause the program to crash or operate incorrectly. Stack buffer overflow is a type of the more general programming malfunction known as buffer overflow (or buffer overrun). Overfilling a buffer on the stack is more likely to derail program execution than overfilling a buffer on the heap be

rdfs:comment	Přetečení na zásobníku (anglicky stack buffer overflow) je v informatice technika napadení programu nebo operačního systému, která využívá přetečení na zásobníku volání ke spuštění libovolného strojového kódu, například přepsáním návratové adresy pro návrat z podprogramu. Přetečení na zásobníku je jedním z nejznámějších způsobů získání neautorizovaného přístupu k počítači. (cs) En informática, un desbordamiento de pila (stack overflow/overrun) es un problema aritmético que hace referencia al exceso de almacenados en la pila de una función, esto permite que la de la pila pueda ser modificada por otra parte de un atacante para obtener un beneficio propio, que generalmente es malicioso. (es) 栈缓冲区溢出（stack buffer overflow或stack buffer overrun）是计算机程序把数据写入调用栈上的内存时超出了数据结构的边界。栈缓冲区溢出是缓冲区溢出的一种。这会损坏相邻数据的值，引发程序崩溃或者修改了函数返回地址从而导致执行恶意的程序。这种攻击方式称为stack smashing。可被用于注入可执行代码、接管进程的执行。是最为古老的黑客攻击行为之一。 (zh) In software, a stack buffer overflow or stack buffer overrun occurs when a program writes to a memory address on the program's call stack outside of the intended data structure, which is usually a fixed-length buffer.Stack buffer overflow bugs are caused when a program writes more data to a buffer located on the stack than what is actually allocated for that buffer.

(ko) В програмах, переповнення буфера стеку трапляється, коли програма пише за адресами в програмному стеку виклику поза призначеною структурою даних; це зазвичай буфер фіксованої довжини.Баг переповнення буфера стеку трапляється, коли програма пише більше даних в буфер розміщений в стеку, ніж було фактично виділено місця для буфера. Це майже завжди призводить до псування прилеглих даних в стеку, і в разі якщо переповнення було зроблено помилково, часто призводить до краху програми або некоректної роботи. Цей тип переповнення є одним з випадківзагальнішого класу багів програмування, знаних як переповнення буфера. (uk)
