CVE-2024-41206
📋 TL;DR
A stack-based buffer over-read vulnerability in tsMuxer allows attackers to read beyond allocated memory boundaries when processing specially crafted TS video files. This can lead to information disclosure of sensitive data from the application's memory. Users who process untrusted TS video files with vulnerable versions of tsMuxer are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers could extract sensitive information from application memory, potentially including credentials, encryption keys, or other confidential data stored in the process memory space.
Likely Case
Information disclosure of random memory contents, potentially revealing fragments of sensitive data or causing application instability/crashes.
If Mitigated
Limited impact with proper input validation and memory protection mechanisms in place, potentially just causing application crashes.
🎯 Exploit Status
Exploitation requires crafting a malicious TS video file; no authentication needed to trigger the vulnerability when processing files.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub repository for latest version after March 14, 2024
Vendor Advisory: https://github.com/justdan96/tsMuxer/issues/859
Restart Required: No
Instructions:
1. Visit tsMuxer GitHub repository 2. Download latest version 3. Replace existing tsMuxer binary with patched version
🔧 Temporary Workarounds
Input Validation
allImplement strict validation of TS video files before processing with tsMuxer
Sandbox Execution
linuxRun tsMuxer in isolated environment or container when processing untrusted files
docker run --rm -v $(pwd):/data tsMuxer-container input.ts
🧯 If You Can't Patch
- Restrict tsMuxer usage to trusted, verified TS video files only
- Implement network segmentation to limit access to systems running tsMuxer
🔍 How to Verify
Check if Vulnerable:
Check tsMuxer version; if using nightly-2024-03-14-01-51-12 or earlier, assume vulnerableCheck Version:
tsMuxeR --version or check binary propertiesVerify Fix Applied:
Update to latest version from GitHub and test with known safe TS files📡 Detection & Monitoring
