CVE-2022-2454
📋 TL;DR
CVE-2022-2454 is an integer overflow vulnerability in the GPAC multimedia framework that could allow attackers to cause denial of service or potentially execute arbitrary code. This affects users and applications that process untrusted media files with GPAC versions prior to the fix. The vulnerability is triggered when parsing specially crafted media files.
💻 Affected Systems
- GPAC (GPAC Project on Advanced Content)
📦 What is this software?
Gpac by Gpac
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise if the integer overflow enables memory corruption that can be weaponized.
Likely Case
Denial of service through application crashes when processing malicious media files.
If Mitigated
Limited impact with proper input validation and sandboxing of media processing components.
🎯 Exploit Status
Exploitation requires crafting a malicious media file that triggers the integer overflow. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Fixed in commit faa75edde3dfeba1e2cf6ffa48e45a50f1042096 and later versions
Vendor Advisory: https://github.com/gpac/gpac/commit/faa75edde3dfeba1e2cf6ffa48e45a50f1042096
Restart Required: Yes
Instructions:
1. Update GPAC to version including commit faa75edde3dfeba1e2cf6ffa48e45a50f1042096 or later. 2. Rebuild any applications using GPAC libraries. 3. Restart affected services using GPAC.
🔧 Temporary Workarounds
Input validation for media files
allImplement strict validation and sanitization of media files before processing with GPAC
Sandbox media processing
linuxRun GPAC-based media processing in isolated containers or sandboxes
docker run --read-only --cap-drop=ALL -v /tmp:/tmp:ro gpac-container
🧯 If You Can't Patch
- Implement network segmentation to isolate media processing systems
- Deploy application allowlisting to prevent execution of unauthorized media processing tools
🔍 How to Verify
Check if Vulnerable:
Check GPAC version: gpac -version and verify it's older than commit faa75edde3dfeba1e2cf6ffa48e45a50f1042096Check Version:
gpac -version 2>/dev/null || mp4box -version 2>/dev/null || echo 'GPAC not found'Verify Fix Applied:
Verify GPAC version includes commit faa75edde3dfeba1e2cf6ffa48e45a50f1042096: git log --oneline | grep faa75ed📡 Detection & Monitoring
Log Indicators:
- GPAC process crashes
- Segmentation faults in media processing
- Abnormal memory usage spikes
Network Indicators:
- Unusual media file uploads to processing endpoints
- Multiple failed media processing attempts
