CVE-2024-32610

What it actually does

The flaw triggers a segmentation fault inside H5T_close_real in H5T.c that corrupts the instruction pointer, allowing memory corruption during HDF5 type cleanup.

Why it matters to the business

Applications that read or write HDF5 files may crash or become entry points for code execution, interrupting scientific, analytics, and monitoring workloads that depend on the library.

How an attack unfolds

An attacker supplies a specially crafted HDF5 file or in-memory dataset; when the victim application opens the data and later closes the associated type object, H5T_close_real dereferences invalid memory and corrupts the instruction pointer.

How to fix it

Upgrade hdfgroup/hdf5 to commit 88429b015e29c59de604b0f552001fb7cb7ed5d0 or later; apply the equivalent fix f266f4ade1defcbfa9fe91930e10b21b2411a3a4 to any pandorafms/pandorafms deployments that embed the library.

How to confirm the fix worked

Confirm the installed HDF5 shared library or source tree matches a fixed commit; re-run regression tests that previously exercised H5T_close_real with malformed type descriptors.

Typical attack path

1. Deliver malicious HDF5 content via file, network stream, or API call
2. Trigger H5T type creation or conversion operations
3. Force H5T_close_real to execute on corrupted internal state
4. Achieve instruction-pointer corruption leading to crash or control-flow hijack

How to detect it

Search application and system logs for segmentation faults or fatal signals occurring inside libhdf5 during type-close operations; correlate with recent file ingestion events involving HDF5 datasets.

What your security team should do

• Prioritize patching any internet-facing or high-value data-processing services that use HDF5
• Inventory all containers, packages, and build pipelines that depend on hdfgroup/hdf5 <= 1.14.3
• Add library-version checks to CI/CD pipelines and SBOM generation
• Monitor crash-reporting systems for segmentation faults originating from H5T_close_real
