  2. NOP (code) - Wikipedia

    en.wikipedia.org/wiki/NOP_(code)

    0x66 is the operand-size override prefix. 0x0F 0x1F is a two-byte NOP opcode that takes a ModRM operand upon which no operation is performed; 0x00 is [EAX], 0x40 0x00 is [EAX + 00H], 0x44 0x00 0x00 is [EAX + EAX*1 + 00H], 0x80 0x00 0x00 0x00 0x00 is [EAX + 00000000H], and 0x84 0x00 0x00 0x00 0x00 0x00 is [EAX + EAX*1 + 00000000H].

  3. Buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Buffer_overflow

    Visualization of a software buffer overflow. Data is written into A, but is too large to fit within A, so it overflows into B.. In programming and information security, a buffer overflow or buffer overrun is an anomaly whereby a program writes data to a buffer beyond the buffer's allocated memory, overwriting adjacent memory locations.

  4. NOP slide - Wikipedia

    en.wikipedia.org/wiki/NOP_slide

    A NOP-sled is the oldest and most widely known technique for exploiting stack buffer overflows. [2] It solves the problem of finding the exact address of the buffer by effectively increasing the size of the target area. To do this, much larger sections of the stack are corrupted with the no-op machine instruction.

  5. Memory safety - Wikipedia

    en.wikipedia.org/wiki/Memory_safety

    Buffer overflow – out-of-bound writes can corrupt the content of adjacent objects, or internal data (like bookkeeping information for the heap) or return addresses. Buffer over-read – out-of-bound reads can reveal sensitive data or help attackers bypass address space layout randomization .

  6. Buffer overflow protection - Wikipedia

    en.wikipedia.org/wiki/Buffer_overflow_protection

    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 because the stack contains the return addresses for all active function calls. [1] Stack buffer overflow can ...
