An update for hdf5 is now available for openEuler-24.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-2186 Final 1.0 1.0 2026-05-03 Initial 2026-05-03 2026-05-03 openEuler SA Tool V1.0 2026-05-03 hdf5 security update An update for hdf5 is now available for openEuler-24.03-LTS-SP1 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. This affects the function H5Z__scaleoffset_decompress_one_byte of the component Scale-Offset Filter. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The vendor plans to fix this issue in an upcoming release.(CVE-2025-2308) An update for hdf5 is now available for master/openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP3/openEuler-22.03-LTS-SP4/openEuler-24.03-LTS/openEuler-24.03-LTS-Next/openEuler-24.03-LTS-SP1/openEuler-24.03-LTS-SP2/openEuler-24.03-LTS-SP3/openEuler-24.03-LTS-SP4. openEuler Security has rated this update as having a security impact of high.
