How to fix?

There is no fixed version for Echo:latest hdf5.

NVD Description

Note: Versions mentioned in the description apply only to the upstream hdf5 package and not the hdf5 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

NULL pointer dereference in H5Pget_fill_value in HDF5 before 2.3.0 allows attackers to cause a denial of service via a dataset whose version 1 or 2 fill value message has the "defined" flag set together with a negative size field, which is not normalized to the library's "undefined" sentinel and reaches H5T_path_find with a NULL datatype.
