CVE-2025-65407
📋 TL;DR
This vulnerability is a use-after-free flaw in Live555 Streaming Media's MPEG1or2Demux component that allows attackers to cause denial of service by sending specially crafted MPEG Program streams. Systems using Live555 for media streaming are affected, particularly those processing untrusted MPEG content. The vulnerability can crash the media server, disrupting streaming services.
💻 Affected Systems
- Live555 Streaming Media
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption with potential for remote code execution if combined with other vulnerabilities, though CVE-2025-65407 alone only causes DoS.
Likely Case
Service crashes and denial of service when processing malicious MPEG streams, requiring service restart.
If Mitigated
Minimal impact if proper input validation and memory safety controls are implemented.
🎯 Exploit Status
Exploitation requires crafting a malicious MPEG Program stream. No authentication needed as it targets the media processing component.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: Yes
Instructions:
1. Monitor Live555 repository for security updates
2. Apply patch when available
3. Recompile and redeploy Live555
4. Restart all services using Live555
🔧 Temporary Workarounds
Input Validation Filter
allImplement network filtering to block or sanitize MPEG Program streams from untrusted sources
Service Isolation
linuxRun Live555 in isolated containers with resource limits to contain crashes
docker run --memory=512m --cpus=1 -d live555-container
🧯 If You Can't Patch
- Implement strict network segmentation to limit access to Live555 services
- Deploy WAF or IPS rules to detect and block malicious MPEG streams
🔍 How to Verify
Check if Vulnerable:
Check if system uses Live555 v2018.09.02 or earlier and processes MPEG streamsCheck Version:
Check Live555 source code or build configuration for version informationVerify Fix Applied:
Verify Live555 version is updated beyond v2018.09.02 when patch is available📡 Detection & Monitoring
Log Indicators:
- Live555 process crashes
- Segmentation fault errors in system logs
- Abnormal termination of media streaming services
Network Indicators:
- Unusual MPEG stream patterns
- Multiple connection attempts with malformed media data
