Summary
[none]
Details

FreeRDP before 3.32.2 does not check the product of surface dimensions in gdi_CreateSurface when handling an RDPGFX CREATE_SURFACE PDU, causing an integer wrap and heap buffer overflow on 32-bit builds and an approximately 4 GiB allocation on 64-bit builds. A malicious RDP server can send a CREATE_SURFACE PDU with width and height 32766 to a connecting client to corrupt heap memory or cause a denial of service.
