CVE-2025-70310
📋 TL;DR
A heap overflow vulnerability in GPAC's vorbis_to_intern() function allows attackers to cause Denial of Service (DoS) by processing a malicious .ogg file. This affects systems running GPAC v2.4.0 for multimedia processing.
💻 Affected Systems
- GPAC (Multimedia Framework)
📦 What is this software?
Gpac by Gpac
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption through application crash, potentially leading to system instability if GPAC runs with high privileges.
Likely Case
Application crash and DoS when processing malicious .ogg files, requiring service restart.
If Mitigated
Minimal impact with proper input validation and sandboxing in place.
🎯 Exploit Status
Proof-of-concept available in GitHub repository; exploitation requires victim to process crafted .ogg file.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor GPAC security advisories for patch release. 2. Upgrade to patched version when available. 3. Test in non-production environment first.
🔧 Temporary Workarounds
Disable Vorbis Audio Processing
linuxTemporarily disable GPAC's Vorbis audio codec support to prevent exploitation.
# Recompile GPAC with --disable-vorbis flag
./configure --disable-vorbis
make clean && make && make install
Input File Validation
allImplement strict file validation for .ogg files before processing.
# Example: Use file command to verify file type
file input.ogg | grep -i 'ogg vorbis'
🧯 If You Can't Patch
- Implement network segmentation to isolate GPAC servers from untrusted networks.
- Deploy application sandboxing/containerization to limit impact of crashes.
🔍 How to Verify
Check if Vulnerable:
Check GPAC version: gpac -version | grep 'GPAC'Check Version:
gpac -version 2>/dev/null | head -1Verify Fix Applied:
Verify version is not v2.4.0 after upgrade; test with known safe .ogg files.📡 Detection & Monitoring
Log Indicators:
- GPAC process crashes with segmentation fault
- Abnormal termination when processing .ogg files
- Memory allocation errors in system logs
Network Indicators:
- Unusual .ogg file uploads to media processing services
- Multiple failed processing attempts
SIEM Query:
