CVE-2024-47774
📋 TL;DR
This CVE describes an out-of-bounds read vulnerability in GStreamer's subtitle parsing function. Attackers could exploit this to read sensitive memory contents or potentially cause denial of service. Any application using vulnerable GStreamer versions for media processing is affected.
💻 Affected Systems
- GStreamer
📦 What is this software?
Gstreamer by Gstreamer Project
⚠️ Risk & Real-World Impact
Worst Case
Information disclosure through memory reading, potential remote code execution if combined with other vulnerabilities, or application crash leading to denial of service.
Likely Case
Application crash causing denial of service, or information leakage from process memory.
If Mitigated
Limited impact if proper memory protections (ASLR, DEP) are enabled, though information disclosure remains possible.
🎯 Exploit Status
Exploitation requires crafting a malicious AVI file with subtitle chunks. The vulnerability is triggered during file parsing.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.24.10
Vendor Advisory: https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/8043.patch
Restart Required: Yes
Instructions:
1. Identify GStreamer version using 'gst-launch-1.0 --version'
2. Update to version 1.24.10 or later using your package manager
3. Restart all applications using GStreamer
4. Verify the update with 'gst-launch-1.0 --version'
🔧 Temporary Workarounds
Disable AVI subtitle parsing
allConfigure applications to disable AVI subtitle processing if not needed
Application-specific configuration required
Input validation
allImplement file type validation and sanitization before passing to GStreamer
Implement custom file validation in application code
🧯 If You Can't Patch
- Implement network segmentation to isolate vulnerable systems
- Use application allowlisting to restrict which applications can process media files
🔍 How to Verify
Check if Vulnerable:
Check GStreamer version with 'gst-launch-1.0 --version' and compare to 1.24.10Check Version:
gst-launch-1.0 --versionVerify Fix Applied:
Verify version is 1.24.10 or higher with 'gst-launch-1.0 --version'📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing AVI files
- Memory access violation errors in application logs
- Unexpected process termination
Network Indicators:
- Unusual AVI file transfers to media processing systems
SIEM Query:
