FreeRDP has heap-use-after-free in xf_AppUpdateWindowFromSurface (stale XImage)
Summary
FreeRDP has heap-use-after-free in xf_AppUpdateWindowFromSurface (stale XImage)
Original description
The description as published by the source.
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_AppUpdateWindowFromSurface reuses a cached XImage whose data pointer references a freed RDPGFX surface buffer, because gdi_DeleteSurface frees surface->data without invalidating the appWindow->image that aliases it. Version 3.23.0 fixes the issue.
