Investigating Windows Graphics Vulnerabilities: A Reverse Engineering and Fuzzing Story
Vulnerabilities targeting Windows applications and components are on the most-wanted list. A survey conducted by Recorded Future concludes that eight of the top 10 most exploited vulnerabilities in 2018 were, in fact Microsoft Office bugs. One of the libraries that most of the Windows applications exploy is Windows Graphics Device Interface (GDI+). This year only, more than 30 vulnerabilities were found for this component. This presentation focuses on identifying the root cause of one of the reported GDI+ vulnerabilities and obtaining a crash correlated to it, which represents an essential building block for developing a fully working exploit. I’ll introduce to you how binary diff-ing and fuzzing can be used in the exploit development process.
