CVE-2024-29164
📋 TL;DR
CVE-2024-29164 is a critical stack buffer overflow vulnerability in HDF5 library versions through 1.14.3. Exploitation can corrupt the instruction pointer, leading to denial of service or potential remote code execution. Any application or system using vulnerable HDF5 libraries for reading 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 full system compromise, allowing attackers to execute arbitrary code with the privileges of the HDF5 process.
Likely Case
Denial of service through application crashes when processing malicious HDF5 files, potentially disrupting data processing workflows.
If Mitigated
Limited impact if proper input validation and sandboxing are implemented, though application crashes may still occur.
🎯 Exploit Status
Exploitation requires processing a malicious HDF5 file, which could be delivered via various vectors including file uploads or network shares.
🛠️ 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 the HDF Group website. 2. Uninstall the vulnerable HDF5 version. 3. Install HDF5 1.14.4. 4. Recompile any applications that link against HDF5. 5. Restart affected services and applications.
🔧 Temporary Workarounds
Input validation for HDF5 files
allImplement strict validation of HDF5 files before processing, rejecting files from untrusted sources.
Sandbox HDF5 processing
allRun HDF5 file processing in isolated containers or sandboxes with minimal privileges.
🧯 If You Can't Patch
- Implement network segmentation to isolate systems using HDF5 from untrusted networks.
- Deploy application allowlisting to prevent execution of unauthorized binaries that might exploit the vulnerability.
🔍 How to Verify
Check if Vulnerable:
Check HDF5 library version using 'h5dump --version' or by examining linked libraries in applications.Check Version:
h5dump --version | grep 'HDF5'Verify Fix Applied:
Confirm HDF5 version is 1.14.4 or later using version check commands and verify applications are linked against the patched library.📡 Detection & Monitoring
