This affects the hdf5 versions delivered by RHOS. However, there is very low likelihood that an attacker would be able to exploit this in a meaningful way through gnocchi. 

Dependency trail.
  gnocchi->python-pandas->python-tables->hdf5

By default RHOS:

"To store the aggregated measures, Gnocchi relies on either Swift or Ceph (Object Storage). Gnocchi also leverages MySQL to store the index of resources and metrics." HDF5 is a lose requirement.
