Technical details
The vulnerability is a NULL pointer dereference in the gdi_Bitmap_Paint function triggered by a zero-width RDPGFX ResetGraphics PDU. When gdi_resize_ex is called with zero dimensions, it frees the primary display surface but fails to recreate it, leaving the pointer null. A subsequent bitmap update attempts to dereference this null pointer, crashing the client. The attack requires a network connection to an RDP server and occurs after graphics capability exchange.
