  "description": "FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, \u0060xf_AppUpdateWindowFromSurface\u0060 reuses a cached \u0060XImage\u0060 whose \u0060data\u0060 pointer references a freed RDPGFX surface buffer, because \u0060gdi_DeleteSurface\u0060 frees \u0060surface-\u003Edata\u0060 without invalidating the \u0060appWindow-\u003Eimage\u0060 that aliases it.
