A data race has been discovered in FreeRDP. This race condition exists between the RDPGFX dynamic virtual channel thread and the SDL render thread and leads to a heap use-after-free. Specifically, an escaped pointer to sdl->primary (SDL_Surface) is accessed after it has been freed during RDPGFX ResetGraphics handling.
