  2. Heap overflow - Wikipedia

    en.wikipedia.org/wiki/Heap_overflow

    The canonical heap overflow technique overwrites dynamic memory allocation linkage (such as malloc metadata) and uses the resulting pointer exchange to overwrite a program function pointer. For example, on older versions of Linux , two buffers allocated next to each other on the heap could result in the first buffer overwriting the second ...

  3. Buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Buffer_overflow

    The canonical heap overflow technique overwrites dynamic memory allocation linkage (such as malloc meta data) and uses the resulting pointer exchange to overwrite a program function pointer. Microsoft's GDI+ vulnerability in handling JPEGs is an example of the danger a heap overflow can present. [5]

  4. Memory safety - Wikipedia

    en.wikipedia.org/wiki/Memory_safety

    A guard page typically halts the program, preventing memory corruption, but functions with large stack frames may bypass the page, and kernel code may not have the benefit of guard pages. Heap exhaustion – the program tries to allocate more memory than the amount available. In some languages, this condition must be checked for manually after ...

  5. 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.

  6. Stack buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Stack_buffer_overflow

    Stack buffer overflow is a type of the more general programming malfunction known as buffer overflow (or buffer overrun). [1] 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.

  7. Overflow - Wikipedia

    en.wikipedia.org/wiki/Overflow

    Integer overflow, a condition that occurs when an integer calculation produces a result that is greater than what a given register can store or represent; Buffer overflow, a situation whereby the incoming data size exceeds that which can be accommodated by a buffer. Heap overflow, a type of buffer overflow that occurs in the heap data area

  8. Buffer underrun - Wikipedia

    en.wikipedia.org/wiki/Buffer_underrun

    The simplest guard against such problems is to increase the size of the buffer—if an incoming data stream needs to be read at 1 bit per second, a buffer of 10 bits would allow the connection to be blocked for up to 10 seconds before failing, whereas one of 60 bits would allow a blockage of up to a minute. However, this requires more memory to ...

  9. The Art of Computer Programming - Wikipedia

    en.wikipedia.org/.../The_Art_of_Computer_Programming

    The Art of Computer Programming (TAOCP) is a comprehensive monograph written by the computer scientist Donald Knuth presenting programming algorithms and their analysis. Volumes 1–5 are intended to represent the central core of computer programming for sequential machines.
