certain message types support a\nparticular flag, the HDF5 1.8.16 library will cast the structure to an\nalternative structure and then assign to fields that aren't supported by\nthe message type and the library will write outside the bounds of the\nheap buffer. This can lead to code execution under the context of the\nlibrary (CVE-2016-4332).\n\nThe HDF5 1.8.16 library allocating space for the array using a value\nfrom the file has an impact within the loop for initializing said array\nallowing a value within the file to modify the loop's terminator.
