There is a NULL pointer dereference vulnerability in VTK before 9.2.5, and
it lies in IO/Infovis/vtkXMLTreeReader.cxx. The vendor didn’t check the
return value of libxml2 API ‘xmlDocGetRootElement’, and try to dereference
it. It is unsafe as the return value can be NULL and that NULL pointer
dereference may crash the application.
