Description Laura Pardo 2018-09-28 15:37:34 EDT 
A flaw was found in HDF HDF5 through 1.10.3 library. A heap-based buffer over-read in H5O_attr_decode() in H5Oattr.c allows attackers to cause a denial of service via a crafted HDF5 file. This issue was triggered while converting an HDF file to GIF file.
