CVE-2024-29161
📋 TL;DR
CVE-2024-29161 is a heap buffer overflow vulnerability in HDF5 library versions through 1.14.3 that can corrupt the instruction pointer when processing HDF5 files. This allows attackers to cause denial of service or potentially execute arbitrary code by providing malicious HDF5 files. Any application or system using vulnerable HDF5 libraries to process untrusted HDF5 files is affected.
💻 Affected Systems
- HDF5 library
- Applications using HDF5 libraries
📦 What is this software?
Hdf5 by Hdfgroup
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the process using HDF5, potentially leading to full system compromise.
Likely Case
Denial of service through application crashes when processing malicious HDF5 files.
If Mitigated
Limited impact with proper sandboxing and input validation, though crashes may still occur.
🎯 Exploit Status
Exploitation requires crafting malicious HDF5 files and getting them processed by vulnerable systems.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: HDF5 1.14.4
Vendor Advisory: https://www.hdfgroup.org/2024/05/new-hdf5-cve-issues-fixed-in-1-14-4/
Restart Required: Yes
Instructions:
1. Download HDF5 1.14.4 from official HDF Group website. 2. Replace existing HDF5 installation with patched version. 3. Recompile any applications using HDF5 libraries. 4. Restart affected services.
🔧 Temporary Workarounds
Input Validation
allImplement strict validation of HDF5 files before processing
Sandboxing
linuxRun HDF5 processing in isolated containers or sandboxes
docker run --read-only --security-opt=no-new-privileges -v /safe/input:/input:ro your_app
🧯 If You Can't Patch
- Implement strict file upload controls and validation for HDF5 files
- Isolate HDF5 processing to dedicated systems with minimal privileges
🔍 How to Verify
Check if Vulnerable:
Check HDF5 library version: h5dump --version or check linked libraries in applicationsCheck Version:
h5dump --version 2>/dev/null | head -1Verify Fix Applied:
Verify HDF5 version is 1.14.4 or later: h5dump --version | grep -q '1.14.4'📡 Detection & Monitoring
