CVE-2024-39130
📋 TL;DR
A NULL pointer dereference vulnerability in DumpTS v0.1.0-nightly allows attackers to crash the application by triggering the DumpOneStream() function with malformed input. This affects anyone using the vulnerable version of DumpTS for TS (Transport Stream) file analysis. The vulnerability results in denial of service but does not allow code execution.
💻 Affected Systems
- DumpTS
⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete application crash and denial of service, potentially disrupting TS file processing workflows that rely on DumpTS.
Likely Case
Application crash when processing specially crafted TS files, requiring manual restart of the DumpTS process.
If Mitigated
Minimal impact if application is isolated and crashes don't affect other services; normal operation resumes after restart.
🎯 Exploit Status
The GitHub issue includes technical details that could be used to create an exploit. Since DumpTS processes external files, exploitation requires only providing a malicious TS file.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub repository for updated version
Vendor Advisory: https://github.com/wangf1978/DumpTS/issues/20
Restart Required: Yes
Instructions:
1. Check the DumpTS GitHub repository for updated version. 2. Replace the vulnerable binary with patched version. 3. Restart any processes using DumpTS.
🔧 Temporary Workarounds
Input validation wrapper
linuxCreate a wrapper script that validates TS files before passing to DumpTS
#!/bin/bash
# Validate file exists and has minimum size
if [ ! -f "$1" ] || [ $(stat -c%s "$1") -lt 100 ]; then
echo "Invalid input file"
exit 1
fi
# Run DumpTS with validated input
./DumpTS "$1"
🧯 If You Can't Patch
- Isolate DumpTS execution in a container or sandbox to limit crash impact
- Implement monitoring to automatically restart DumpTS if it crashes
🔍 How to Verify
Check if Vulnerable:
Check DumpTS version: run 'DumpTS --version' or check binary metadata. If version is v0.1.0-nightly, it's vulnerable.Check Version:
DumpTS --versionVerify Fix Applied:
Test with known problematic TS files from the GitHub issue; application should not crash.📡 Detection & Monitoring
