An issue was discovered in the HDF HDF5 1.10.3 library. There is a stack-based buffer overflow in the function H5Sextentgetdims() in H5S.c. Specifically, this issue occurs while converting an HDF5 file to a GIF file.
A SIGFPE signal is raised in the function H5Dselectio() of H5Dselect.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.
A heap-based buffer over-read in H5Oattrdecode() 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.
A NULL pointer dereference in H5Osdspaceencode() in H5Osdspace.c in the HDF HDF5 through 1.10.3 library allows attackers to cause a denial of service via a crafted HDF5 file.
A heap-based buffer overflow in ReadGifImageDesc() in gifread.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 a GIF file to an HDF file.
ReadCode() in decompress.c in the HDF HDF5 through 1.10.3 library allows attackers to cause a denial of service (invalid write access) via a crafted HDF5 file. This issue was triggered while converting a GIF file to an HDF file.
A SIGFPE signal is raised in the function H5Dchunksetinforeal() 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 H5Dcreatechunkfilemaphyper() 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.
A SIGFPE signal is raised in the function applyfilters() of h5repackfilters.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.
Memory leak in the H5Odtypedecodehelper() function in H5Odtype.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.
Memory leak in the H5Ochunkdeserialize() 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.
