CVE-2018-17233

It could allow a remote denial of service attack.

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 H5D__create_chunk_file_map_hyper() of H5Dchunk.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.
