CVE-2024-53432
📋 TL;DR
This vulnerability allows attackers to cause denial-of-service by crashing applications that use PCL 1.14.1 to process malicious PLY files. Anyone using Point Cloud Library to handle untrusted 3D point cloud data is affected. The crash occurs due to an uncaught exception when parsing malformed PLY file headers.
💻 Affected Systems
- Point Cloud Library (PCL)
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption for applications processing PLY files, potentially affecting critical systems that rely on 3D point cloud processing.
Likely Case
Application crashes when processing malicious PLY files, requiring manual restart and causing temporary service interruption.
If Mitigated
No impact if proper input validation and exception handling are implemented, or if untrusted PLY files are not processed.
🎯 Exploit Status
Exploitation requires only a malformed PLY file, making it easy to weaponize. No authentication needed if file upload/processing is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for latest fix
Vendor Advisory: https://github.com/PointCloudLibrary/pcl/issues/6162
Restart Required: Yes
Instructions:
1. Monitor the GitHub issue for official patch release. 2. Update PCL to patched version when available. 3. Rebuild and redeploy applications using PCL. 4. Restart affected services.
🔧 Temporary Workarounds
Input Validation
allImplement strict validation of PLY file headers before processing
Exception Handling
allWrap PLY file processing in try-catch blocks to handle std::out_of_range exceptions
🧯 If You Can't Patch
- Isolate PLY file processing to dedicated containers/sandboxes
- Implement file type verification and reject suspicious PLY files
🔍 How to Verify
Check if Vulnerable:
Check if PCL version is 1.14.1 and application processes PLY filesCheck Version:
pkg-config --modversion pcl_commonVerify Fix Applied:
Test with known malformed PLY files to ensure application doesn't crash📡 Detection & Monitoring
Log Indicators:
- Application crashes with std::out_of_range exceptions
- Abnormal termination of PCL processes
Network Indicators:
- Multiple failed PLY file uploads
- Unusual PLY file sizes or headers
