Fedora 45 : python-h5io (2026-4a16e04d4b)

high Nessus Plugin ID 381480

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 45 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-4a16e04d4b advisory.

 Update to 0.2.6 upstream release

 This release fixes [GHSA-vwvw-f6v4-w737](https://github.com/h5io/h5io/security/advisories/GHSA-vwvw-f6v4-w737) / [CVE-2026-120499](https://www.cve.org/CVERecord?id=CVE-2026-120499):
 `read_hdf5` could execute arbitrary code when reading a crafted HDF5 file.

 As part of the fix, loading files containing classes, objects written with `use_state=True`, or pandas `DataFrame`/`Series` objects is disabled by default and will now raise a `ValueError`; see the [release notes](https://github.com/h5io/h5io/releases/tag/h5io-0.2.6) for details.


Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected python-h5io package.
