CVE-2025-47183
📋 TL;DR
This vulnerability in GStreamer's isomp4 plugin allows attackers to read beyond allocated heap buffer boundaries when parsing malicious MP4 files. This can lead to memory disclosure and potential information leakage. Any application using GStreamer to process MP4 files is affected.
💻 Affected Systems
- GStreamer
📦 What is this software?
Gstreamer by Gstreamer Project
⚠️ Risk & Real-World Impact
Worst Case
Memory disclosure could expose sensitive data like encryption keys, credentials, or application memory contents, potentially enabling further attacks.
Likely Case
Information disclosure from process memory, possibly revealing file contents or other data being processed by GStreamer.
If Mitigated
Limited impact with proper sandboxing and memory protection mechanisms in place.
🎯 Exploit Status
Requires user to open a malicious MP4 file or for an application to process such a file.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: GStreamer 1.26.2 or later
Vendor Advisory: https://gstreamer.freedesktop.org/security/
Restart Required: No
Instructions:
1. Check current GStreamer version. 2. Update to GStreamer 1.26.2 or later using your distribution's package manager. 3. Verify the update was successful.
🔧 Temporary Workarounds
Disable isomp4 plugin
allPrevent GStreamer from using the vulnerable isomp4 plugin
gst-inspect-1.0 --plugin-filters | grep isomp4
export GST_PLUGIN_PATH=/path/to/safe/plugins
🧯 If You Can't Patch
- Implement strict input validation for MP4 files
- Run GStreamer in a sandboxed environment with limited memory access
🔍 How to Verify
Check if Vulnerable:
Check GStreamer version with 'gst-inspect-1.0 --version' and verify if it's 1.26.1 or earlierCheck Version:
gst-inspect-1.0 --versionVerify Fix Applied:
Confirm version is 1.26.2 or later with 'gst-inspect-1.0 --version'📡 Detection & Monitoring
