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.
H5Z__filter_nbit in H5Znbit.c in HDF5 through 2.3.0 dereferences cd_values[0] through cd_values[4] without validating that cd_values is non-NULL or that cd_nelmts is at least 5, the fixed size of the filter's header. This allows attackers to cause a denial of service via a crafted HDF5 file that stores the N-Bit filter pipeline message with zero client-data values, opened and read via H5Dread, e.g. by the h5ls or h5repack tools.
