CVE-2024-29157
📋 TL;DR
CVE-2024-29157 is a critical heap buffer overflow vulnerability in HDF5 library versions through 1.14.3. Attackers can exploit this to corrupt the instruction pointer, potentially leading to denial of service or remote code execution. Any application or system using vulnerable HDF5 versions for reading HDF5 files is affected.
💻 Affected Systems
- HDF5 library
- Applications using HDF5 library
📦 What is this software?
Hdf5 by Hdfgroup
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with full system compromise, allowing attackers to execute arbitrary code with the privileges of the HDF5 process.
Likely Case
Denial of service through application crashes or system instability when processing malicious HDF5 files.
If Mitigated
Limited impact if proper sandboxing, privilege separation, and input validation are implemented.
🎯 Exploit Status
Exploitation requires crafting malicious HDF5 files, but no public exploit code is currently available.
🛠️ 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. Uninstall vulnerable HDF5 version. 3. Install HDF5 1.14.4. 4. Recompile any applications using HDF5. 5. Restart affected services.
🔧 Temporary Workarounds
Disable HDF5 file processing
allTemporarily disable processing of HDF5 files from untrusted sources
Sandbox HDF5 processing
linuxRun HDF5 processing in isolated containers or VMs with limited privileges
docker run --read-only --cap-drop=ALL -v /safe/input:/input:ro your_app
🧯 If You Can't Patch
- Implement strict input validation to reject malformed HDF5 files
- Deploy network segmentation to isolate HDF5 processing systems
🔍 How to Verify
Check if Vulnerable:
Check HDF5 library version: h5dump --version or check linked library version 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
Log Indicators:
- Application crashes with segmentation faults
- Memory corruption errors in system logs
- Unexpected process termination when processing HDF5 files
Network Indicators:
- Unusual network traffic to/from HDF5 processing systems
- Large HDF5 file transfers from untrusted sources
