hdf5: HDF5 library: Denial of Service via crafted HDF5 file processing

A flaw was found in the HDF5 library. A local user could exploit a double free vulnerability by processing a specially crafted HDF5 file with an oversized chunk size field using the h5repack tool. This could cause the application to unexpectedly terminate, leading to a denial of service...

hdf5: HDF5: Out-of-bounds read due to corrupted file can lead to denial of service

A flaw was found in HDF5, a high-performance library and file format specification. A remote attacker can exploit this vulnerability by providing a maliciously altered HDF5 file. If the file's array datatype has inconsistent size, element count, or element size, it can trigger an out-of-bounds...

hdf5: HDF5: Denial of Service due to malformed chunk data in files

A flaw was found in HDF5. An attacker can craft a malicious HDF5 file that, when opened and read by an application, exploits a validation bypass. This bypass, related to mismatched chunk-layout dimensionality and dataspace rank, leads to a divide-by-zero error, causing a denial of service DoS and...

HDF5: HDF5: Memory corruption via crafted HDF5 file

A flaw was found in HDF5. A heap-use-after-free vulnerability exists when converting a compound datatype containing floating-point members during a dataset read. An attacker can supply a specially crafted HDF5 file, which, when parsed by an application, can trigger this flaw. This can lead to a...
