CVE-2018-17432
A NULL pointer dereference in H5O_sdspace_encode() in H5Osdspace.c in the HDF HDF5 through 1.10.3 library allows attackers to cause a denial of service via a crafted HDF5 file.
Does this matter?
Lower severity and a low EPSS score (1.31%). Track it; it rarely justifies an emergency change on its own.
