CVE-2024-47539
📋 TL;DR
This CVE describes an out-of-bounds write vulnerability in GStreamer's MP4 demuxer that allows attackers to write up to 3 bytes beyond allocated memory bounds. The vulnerability affects all systems using vulnerable versions of GStreamer for media processing. With a CVSS score of 9.8, this is a critical memory corruption vulnerability that could lead to remote code execution.
💻 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, data theft, or ransomware deployment.
Likely Case
Application crash (denial of service) or limited memory corruption potentially leading to information disclosure.
If Mitigated
Application crash with no further impact if memory protections (ASLR, DEP) are effective.
🎯 Exploit Status
Exploitation requires crafting a malicious MP4 file, but the vulnerability is in core library code making exploitation feasible for skilled attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.24.10
Vendor Advisory: https://gstreamer.freedesktop.org/security/sa-2024-0007.html
Restart Required: Yes
Instructions:
1. Update GStreamer to version 1.24.10 or later. 2. For Linux distributions, use package manager: 'sudo apt update && sudo apt upgrade gstreamer1.0' (Debian/Ubuntu) or 'sudo yum update gstreamer' (RHEL/CentOS). 3. Restart all applications using GStreamer.
🔧 Temporary Workarounds
Disable MP4 processing
allDisable or block MP4 file processing in applications using GStreamer
Use input validation
allImplement strict validation of MP4 files before processing with GStreamer
🧯 If You Can't Patch
- Implement network segmentation to isolate systems using GStreamer
- Deploy application allowlisting to prevent execution of unknown media processing applications
🔍 How to Verify
Check if Vulnerable:
Check GStreamer version: 'gst-inspect-1.0 --version' or check package manager for installed version.Check Version:
gst-inspect-1.0 --versionVerify Fix Applied:
Verify version is 1.24.10 or later: 'gst-inspect-1.0 --version | grep -q "1.24.10" && echo "Patched"'📡 Detection & Monitoring
