MEDIUM 6.5EPSS 1.76%
Does this matter?
Lower severity and a low EPSS score (1.76%). Track it; it rarely justifies an emergency change on its own.
Description
A SIGFPE signal is raised in the function apply_filters() of h5repack_filters.c in the HDF HDF5 through 1.10.3 library 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.
