Description Laura Pardo 2018-09-28 15:34:44 EDT 
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.
