NVD Description

Note: Versions mentioned in the description apply only to the upstream hdf5 package and not the hdf5 package as distributed by Ubuntu.

A heap-based buffer over-read in H5O_attr_decode() in H5Oattr.c in the HDF HDF5 through 1.10.3 library allows attackers to cause a denial of service via a crafted HDF5 file. This issue was triggered while converting an HDF file to GIF file.
