A SIGFPE signal is raised in the function H5D__chunk_set_info_real() of H5Dchunk.c in the HDF HDF5 1.10.3 library during an attempted parse of a crafted HDF file, because of incorrect protection against division by zero. This issue is different from CVE-2018-11207.
In HDF5 1.10.1, there is an out of bounds read vulnerability in the function H5Opline_pline_decode in H5Opline.c in libhdf5.a. For example, h5dump would crash when someone opens a crafted hdf5 file.
