CVE-2024-47600
📋 TL;DR
This CVE describes an out-of-bounds read vulnerability in GStreamer's audio channel discovery function. Attackers can trigger memory corruption by processing specially crafted media files, potentially leading to information disclosure or denial of service. Any application using vulnerable GStreamer versions for media processing is affected.
💻 Affected Systems
- GStreamer
- Applications using GStreamer library
📦 What is this software?
Gstreamer by Gstreamer Project
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise via memory corruption and arbitrary code execution.
Likely Case
Application crash (denial of service) or information disclosure through memory read.
If Mitigated
Limited impact with proper sandboxing and memory protection mechanisms.
🎯 Exploit Status
Exploitation requires crafting malicious media files that trigger the OOB-read condition.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.24.10
Vendor Advisory: https://gstreamer.freedesktop.org/security/sa-2024-0018.html
Restart Required: Yes
Instructions:
1. Update GStreamer to version 1.24.10 or later
2. Restart all applications using GStreamer
3. Rebuild any statically linked applications with patched library
🔧 Temporary Workarounds
Disable audio discovery
allDisable gst-discoverer functionality in applications if not required
Application-specific configuration required
Sandbox media processing
linuxRun media processing in isolated containers or sandboxes
docker run --security-opt=no-new-privileges gstreamer-app
firejail --private gstreamer-app
🧯 If You Can't Patch
- Implement strict input validation for media files
- Use application allowlisting to prevent unauthorized media processing
🔍 How to Verify
Check if Vulnerable:
Check GStreamer version with: gst-inspect-1.0 --versionCheck Version:
gst-inspect-1.0 --versionVerify Fix Applied:
Verify version is 1.24.10 or higher: gst-inspect-1.0 --version | grep -q '1.24.1[0-9]\|1.2[5-9]\|[2-9]\.[0-9]'📡 Detection & Monitoring
Log Indicators:
- Application crashes with segmentation faults
- Memory access violation errors in system logs
- Unexpected process termination during media processing
Network Indicators:
- Unusual media file uploads to web applications
- Suspicious media streaming patterns
