CVE-2024-57513
📋 TL;DR
A floating-point exception vulnerability in Bento4's AP4_TfraAtom function allows attackers to cause denial of service by crashing applications that process malicious MP4 files. This affects any software using vulnerable versions of the Bento4 library for media processing. The vulnerability is triggered when parsing specially crafted MP4 container files.
💻 Affected Systems
- Bento4
- Applications using Bento4 library
⚠️ 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 leading to denial of service for media processing services, potentially disrupting video streaming, editing, or conversion workflows.
Likely Case
Application crash when processing malicious MP4 files, causing temporary service disruption until the process restarts.
If Mitigated
Minimal impact with proper input validation and sandboxing; crashes would be contained to isolated processes.
🎯 Exploit Status
Proof-of-concept available in GitHub gist. Exploitation requires only a malicious MP4 file to be processed by vulnerable software. No authentication needed if application accepts file uploads.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in references (check latest Bento4 releases)
Vendor Advisory: https://github.com/axiomatic-systems/Bento4/issues/990
Restart Required: Yes
Instructions:
1. Check Bento4 GitHub repository for latest release
2. Update Bento4 library to patched version
3. Rebuild/redeploy applications using Bento4
4. Restart affected services
🔧 Temporary Workarounds
Input Validation for MP4 Files
allImplement strict validation of MP4 files before processing with Bento4 library
Process Isolation
allRun media processing in isolated containers or sandboxes to contain crashes
🧯 If You Can't Patch
- Implement strict file upload restrictions for MP4 files
- Deploy monitoring to detect and block repeated crash attempts
🔍 How to Verify
Check if Vulnerable:
Test with proof-of-concept MP4 file from GitHub gist; if application crashes, it's vulnerableCheck Version:
Check Bento4 version in application dependencies or library filesVerify Fix Applied:
Test with same proof-of-concept file after update; application should process file without crashing📡 Detection & Monitoring
Log Indicators:
- Application crashes with floating-point exceptions
- Segmentation faults in media processing components
- Repeated process restarts after MP4 file processing
Network Indicators:
- Multiple MP4 file uploads followed by service disruption
- Unusual patterns in media file uploads
SIEM Query:
source="application.log" AND ("floating point" OR "SIGFPE" OR "divide by zero") AND "mp4"
