  Fixed typo Platforms tested:     Darwin (osx1010test)
  Refixed HDFFV-10578 Description:     Applied Neil's fix for this issue after removing previous     attempt.  The resources are now released in init_objs() when     failure occurs there.     Neil will fix HDFFV-10676 separately. Platforms tested:     Linux/64 (jelly)     Linux/64 (platypus)     Darwin (osx1010test)

  Updated per review Description:     HDFFV-10676 - CVE-2018-13873         Changed the new assert to if statement, per Dana's comment. Platforms tested:     Linux/64 (jelly)
  HDFFV-10578 and HDFFV-10676 Description:     HDFFV-10578 - CVE-2018-17234         The file has some issue, however, there was a bug in h5dump that caused         memory leaks after the problem in the file was encountered. The bug         was that an if statement was missing in the function table_list_add()         resulting in the memory not being freed at a later time.         After the fix had been applied, there were no more leaks after h5dump         detected the issue in the file and reported the error.
