A flaw was found in HDF HDF5 through 1.10.3 library. A SIGFPE signal is raised in the function apply_filters() of h5repack_filters.c during an attempted parse of a crafted HDF file, because of incorrect protection against division by zero. It could allow a remote denial of service attack. References: https://github.com/SegfaultMasters/covering360/tree/master/HDF5/vuln4#divided-by-zero---poc_apply_filters_h5repack_filters
