CVE-2024-29157
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 through 1.14.3 contains a heap buffer overflow in H5HG_read, resulting in the corruption of the instruction pointer and causing denial of service or potential code execution.
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 · moderate confidenceA heap buffer overflow vulnerability exists in the H5HG_read function of the HDF5 library (versions through 1.14.3). The overflow allows corruption of the instruction pointer, enabling potential arbitrary code execution or denial of service conditions.

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 installed HDF5 library versionRun 'h5dump --version' or check the shared library version with 'ldd' on any HDF5-linked binary, or inspect the library file metadataAffected if Version returned is 1.14.3 or lower
-
Locate HDF5 library filesSearch for libhdf5 files (e.g., find /usr -name 'libhdf5*' 2>/dev/null) and note the package or build informationAffected if Library files exist and version cannot be determined or is <= 1.14.3
-
Identify applications using HDF5Run 'ldd <binary>' on suspected applications or check package dependencies for libhdf5Affected if Any application is linked against a vulnerable HDF5 library version <= 1.14.3
-
Check for HDF5 file processingReview application logs, filesystem, or network inputs for .h5 or HDF5 file ingestionAffected if The environment processes, reads, or parses HDF5 files from untrusted sources using a vulnerable library version
Environment is affected if HDF5 library version 1.14.3 or lower is installed and any application reads or processes HDF5 files, since the heap buffer overflow in H5HG_read triggers during file parsing.
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.
From vendor dataUpgrade HDF5 to version 1.14.4 or later. If immediate patching is not feasible, restrict processing of untrusted HDF5 files and monitor for anomalous behavior.
