A flaw was found in HDF5. The h5dump tool, used for dumping HDF5 file contents, is vulnerable to an untrusted pointer dereference. An attacker could craft a malicious HDF5 file containing a variable-length string dataset. When this file is processed in binary output mode, it can lead to a denial of service, making the tool unavailable.
