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.

Untrusted pointer dereference in the render_bin_output function in the h5dump tool in HDF5 before 2.3.0 allows attackers to cause a denial of service via a variable-length string dataset with more than one element dumped in binary mode, which corrupts the per-element stride calculation and causes subsequent elements to be read from a misaligned offset and dereferenced as a pointer.
