FreeRDP before 3.32.2 contains a denial of service vulnerability in the RDPGFX ALPHA WIRETOSURFACE_2 handler that fails to validate zero surface dimensions. A malicious RDP server can send a crafted WIRETOSURFACE_2 PDU with zero width and height, triggering an assertion or division by zero that terminates the client session.
