CVE-2024-32612
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedHDF5 Library through 1.14.3 contains a heap-based buffer over-read in H5HL__fl_deserialize in H5HLcache.c, resulting in the corruption of the instruction pointer, a different vulnerability than CVE-2024-32613.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceHeap-based buffer over-read vulnerability in the HDF5 Library's H5HL__fl_deserialize function in H5HLcache.c allows corruption of the instruction pointer during local heap cache deserialization, potentially enabling arbitrary code execution when processing maliciously crafted HDF5 files.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check HDF5 library versionRun 'h5dump --version' or 'h5ls --version' to display the installed HDF5 library version. Alternatively, check the package manager: 'dpkg -l libhdf5' (Debian) or 'rpm -qi hdf5' (RHEL).Affected if Version is below 1.14.4 (for example, 1.14.3, 1.14.2, 1.12.x, etc.)
-
Identify applications linked to HDF5Run 'ldd /path/to/application | grep hdf5' or 'ldconfig -p | grep hdf5' to list binaries that link against the HDF5 library.Affected if The linked HDF5 library version is below 1.14.4
-
Check for HDF5 file processingReview application logs or code to determine if the application reads HDF5 files from external or untrusted sources. Look for file open operations using H5Fopen or similar HDF5 APIs.Affected if The application processes HDF5 files, especially from untrusted or external sources, enabling the vulnerable deserialization code path
You are affected if your installed HDF5 library version is below 1.14.4 and your application or workflow processes HDF5 files, which triggers the vulnerable H5HL__fl_deserialize function.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.14.4
Update HDF5 Library to a version beyond 1.14.3 once a patch is released; validate HDF5 files before processing and restrict untrusted file inputs until patched.
1.14.4
- 1. Identify all systems, applications, or containers that have HDF5 library installed with versions prior to 1.14.4
- 2. Consult your application's dependency management system (e.g., package manager, build system, container base images) to locate HDF5 dependencies
- 3. Upgrade HDF5 to version 1.14.4 or later by updating the dependency version in your project
- 4. Rebuild and recompile any applications that statically link against HDF5
- 5. Re-deploy the updated applications and containers
- 6. Verify the fix by confirming the HDF5 version is now 1.14.4 or higher using tools like 'h5dump --version' or checking the library linked in your application
