An issue was discovered in the HDF HDF5 1.10.3 library. There is a stack-based buffer overflow in the function H5S_extent_get_dims() in H5S.c. Specifically, this issue occurs while converting an HDF5 file to a GIF file.

A heap-based buffer over-read in H5O_attr_decode() in H5Oattr.c in the HDF HDF5 through 1.10.3 library 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.

Memory leak in the H5O__chunk_deserialize() function in H5Ocache.c in the HDF HDF5 through 1.10.3 library allows attackers to cause a denial of service (memory consumption) via a crafted HDF5 file.

A SIGFPE signal is raised in the function H5D__chunk_set_info_real() of H5Dchunk.c in the HDF HDF5 1.10.3 library during an attempted parse of a crafted HDF file, because of incorrect protection against division by zero. This issue is different from CVE-2018-11207.

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.

An issue was discovered in the HDF HDF5 1.8.20 library. There is an out of bounds read in H5L_extern_query at H5Lexternal.c.

An issue was discovered in the HDF HDF5 1.10.2 library. Excessive stack consumption has been detected in the function H5P__get_cb() in H5Pint.c during an attempted parse of a crafted HDF file. This results in denial of service.

An issue was discovered in the HDF HDF5 1.8.20 library. There is a heap-based buffer over-read in the function H5O_sdspace_decode in H5Osdspace.c.

An issue was discovered in the HDF HDF5 1.8.20 library. There is a heap-based buffer over-read in the function H5VM_memcpyvv in H5VM.c.

An issue was discovered in the HDF HDF5 1.8.20 library. There is an out of bounds read in the function H5O_pline_reset in H5Opline.c.
