CVE-2024-32617
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 caused by the unsafe use of strdup in H5MM_xstrdup in H5MM.c (called from H5G__ent_to_link in H5Glink.c).
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 HDF5 Library through 1.14.3 caused by unsafe use of strdup in H5MM_xstrdup function (called from H5G__ent_to_link), potentially allowing memory corruption or information disclosure when processing malicious 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.
-
Identify HDF5 library installationRun 'h5dump --version' or check package manager (dpkg -l libhdf5, rpm -qa hdf5, brew list hdf5)Affected if HDF5 is installed and version displays
-
Determine installed HDF5 versionExecute 'h5dump --version' and note the version number shown (e.g., 1.14.3, 1.14.2, 1.10.8)Affected if Version number is returned but cannot be parsed or compared
-
Compare version to affected rangeCompare your installed version against the vulnerable range: any version less than 1.14.4 is affected (e.g., 1.14.3, 1.14.2, 1.14.1, 1.14.0, 1.13.x, 1.12.x, 1.10.x)Affected if Installed version is < 1.14.4
-
Check for linked applicationsRun 'ldd /path/to/your/application' or 'ldconfig -p | grep hdf5' to see which local applications link to the HDF5 libraryAffected if Applications dynamically link to a vulnerable HDF5 library version
Your environment is affected if HDF5 library version 1.14.3 or any earlier version is installed and used to process HDF5 files.
Generated from the published advisory. Verify against your own configuration.
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 version 1.14.4 or later. Until patched, restrict processing of untrusted HDF5 files and validate input within applications using the library.
HDF5 1.14.4
- 1. Identify the current HDF5 version by running 'h5dump --version' or checking your package manager
- 2. Download HDF5 version 1.14.4 or later from the official HDF Group website (www.hdfgroup.org) or your system's package manager
- 3. If building from source: extract the archive, run './configure', 'make', and 'make install' with appropriate prefix
- 4. If using a package manager: update your repository cache and install the available HDF5 1.14.4+ package
- 5. Update any build configurations (CMake, autoconf, pkg-config) to reference the new library path if not using system defaults
- 6. Rebuild any applications that link against HDF5 to ensure they use the updated library
- 7. Verify the installed version is 1.14.4 or later using 'h5dump --version'
