IO_FILE Heap Exploitation: Understanding fwrite Implementation
To learn IO_FILE-based heap exploitation, we must understand its underlying mechanism. This article examines several key IO functions using source code analysis and dynamic debugging.
1. fwrite Function Overview
1.1 Overall Flow
The main implementation of fwrite resides in _IO_new_file_xsputn, containing four distinct phases:
