Investigating Windows Graphics Vulnerabilities: A Reverse Engineering and Fuzzing Story
Vulnerabilities targeting Microsoft applications remain top priority for malicious actors. Taking into consideration the complexity and the multitude of modules available in Windows OS for example, one approach of identifying interesting weaknesses is fuzzing. This talk showcases in a detailed manner the mindset and the necessary steps to obtain a crash correlated to a Windows GDI+ vulnerability, which represents an essential building block for developing a fully working exploit. We will discuss about how binary diffing and fuzzing tools can be used in the exploit development process and give away some tricks to make your fuzzing campaigns more effective. By the end of the presentation, you should be familiar with harness development and WinAFL quirks, what criteria you should consider when choosing fuzzing targets and how could GDI vulnerabilities be exploited.
