Also known as a buffer overrun, buffer overflow occurs when the amount of data in the buffer exceeds its storage capacity. That extra data overflows into adjacent memory locations and corrupts or overwrites the data in those locations. What Is A Buffer Overflow Attack? A buffer overflow ...
in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
Build and C API Changes Python’s build process和C API的改动包括: PEP3118:新的Buffer API PEP3121:扩展模块的的Initialization & Finalization PEP3123:使PyObject_HEAD符合标准C
Python 2.7 is planned to be the last of the 2.x releases, so we worked on making it a good release for the long term. To help with porting to Python 3, several new features from the Python 3.x series have been included in 2.7....
The buffer protocol is a practical approach in Python that gives access to an object's underlying memory. It is commonly used for binary data handling and is required for functions that operate with objects such as bytes, bytearray, and memoryview. However, Python code could only explicitly che...
named pipes provide an alternative way of communicating between two processes instead of using an anonymous data buffer as regular pipes do. a named pipe creates a file handle which allows both the sender and receiver processes to access the same pipe simultaneously for communication purposes. this...
Stack attacks are the most common way to exploit buffer overflow issues. Heap-based attacks Unlike stack-based overflow, which targets the stack, heap-based attacks target dynamically allocated memory on the heap. This happens when a buffer in the heap - which is a region of a computer's me...
When more code or data is entered into a system buffer than the system was designed to handle, a program security vulnerability known as a Buffer Overflow comes up, by which the excess data overwrites the adjacent memory section of the system; therefore, in such a system, this occurrence cr...
