CVE-2016-3309 is an elevation of privilege vulnerability in the kernel-mode drivers (win32k.sys) of multiple Microsoft Windows versions, including Vista SP2, Windows 7 SP1, Windows 8.1, Windows 10 (Gold, 1511, 1607), Windows Server 2008 (SP2, R2 SP1), Windows Server 2012 (Gold, R2), and Windows RT 8.1. The vulnerability allows a local attacker to gain elevated privileges by executing a specially crafted application. This is a distinct vulnerability from CVE-2016-3308, CVE-2016-3310, and CVE-2016-3311.

This repository is a Visual Studio solution containing three C++ projects, each implementing a different exploit or proof-of-concept for CVE-2016-3309, a 'wild' pool overflow vulnerability in the Windows kernel (win32kfull!bFill). The exploits are designed for Windows 10 x64 Creators Update (build 15063.540). The two main exploit projects (Bitmaps and Palettes) achieve local privilege escalation to SYSTEM by leveraging the pool overflow, while the Deadlock project demonstrates a system deadlock condition related to improved handle validation. The repository includes project and filter files for Visual Studio, and the main exploit logic is expected to reside in the respective main_*.cpp files. No network endpoints are present; the attack vector is local, requiring code execution on the target system. The README provides context and a link to a detailed technical blog post.
