Denial of Service
Under the default condition (when no IoControlCode matches), a normal user can cause DoS due to failing to check a global variable.
In the attached file DoS2.zip, there are DoS2.exe, DoS2.cpp, webcam-for-remote-desktop-server-64bit.msi, and ftwebcam.sys. DoS2.exe is the PoC to cause BSOD where webcam-for-remote-desktop-server-64bit.msi contains the vulnerable driver ftwebcam.sys installed, and DoS2.cpp is the source code of DoS2.exe. To reproduce the issue, install webcam-for-remote-desktop-server-64bit.msi and execute DoS2.exe. It is expected that the system will crash (BSOD) once DoS2.exe is executed.
