CVE-2025-29480
📋 TL;DR
A buffer overflow vulnerability in GDAL 3.10.2's OGRSpatialReference::Release function allows a local attacker to cause denial of service by crashing the application. This affects systems running vulnerable GDAL versions that process malicious spatial data. The vendor disputes the validity of this vulnerability report.
💻 Affected Systems
- GDAL (Geospatial Data Abstraction Library)
📦 What is this software?
Gdal by Osgeo
⚠️ Risk & Real-World Impact
Worst Case
Complete denial of service through application crash, potentially disrupting dependent services that rely on GDAL for spatial data processing.
Likely Case
Application crash when processing specially crafted spatial data files, requiring service restart.
If Mitigated
Minimal impact if proper input validation and memory protections are in place, with crashes contained to individual processes.
🎯 Exploit Status
Exploitation requires local access or ability to supply malicious input to GDAL. Public proof-of-concept exists in GitHub repository.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available - vendor disputes vulnerability validity
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Monitor GDAL releases for potential fixes if vulnerability is confirmed.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement strict input validation for spatial data files processed by GDAL
Process Isolation
linuxRun GDAL in isolated containers or sandboxes to contain potential crashes
docker run --security-opt=no-new-privileges -v /data:/data gdal
🧯 If You Can't Patch
- Restrict local user access to systems running vulnerable GDAL versions
- Implement strict file upload controls and scanning for spatial data files
🔍 How to Verify
Check if Vulnerable:
Check GDAL version: gdalinfo --version. If version is 3.10.2 or potentially other affected versions, system may be vulnerable.Check Version:
gdalinfo --versionVerify Fix Applied:
No official fix available to verify. Monitor GDAL releases for updates addressing this CVE.📡 Detection & Monitoring
