Buffer-overflow is also known as
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 triggere… WebApr 5, 2024 · While buffer overflows are quite well-known now, they're also very commonly exploited (for example, WannaCry exploited a buffer overflow).
