Summary

hdf5 security update

Details

HDF5 is a data model, library, and file format for storing and managing data. It supports an unlimited variety of datatypes, and is designed for flexible and efficient I/O and for high volume and complex data. HDF5 is portable and is extensible, allowing applications to evolve in their use of HDF5. The HDF5 Technology suite includes tools and applications for managing, manipulating, viewing, and analyzing data in the HDF5 format.

Security Fix(es):

A vulnerability, which was classified as critical, was found in HDF5 1.14.6. Affected is the function H5SM_delete of the file H5SM.c of the component h5 File Handler. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used.(CVE-2025-2153)

A vulnerability classified as problematic has been found in HDF5 up to 1.14.6. This affects the function H5FS__sinfo_Srialize_Sct_cb of the file src/H5FScache.c. The manipulation of the argument sect leads to heap-based buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used.(CVE-2025-2914)

A vulnerability, which was classified as problematic, has been found in HDF5 1.14.6. Affected by this issue is the function H5O__mtime_new_encode of the file src/H5Omtime.c. The manipulation leads to heap-based buffer overflow. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used.(CVE-2025-6750)

A vulnerability classified as problematic was found in HDF5 1.14.6. This vulnerability affects the function H5O__fsinfo_encode of the file /src/H5Ofsinfo.c. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.(CVE-2025-6816)

Severity

8.1 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
