CVE-2024-5197
📋 TL;DR
This CVE describes integer overflow vulnerabilities in libvpx (VP8/VP9 video codec library) that can occur when processing large image dimensions or alignment parameters. Attackers could exploit these overflows to cause memory corruption, potentially leading to crashes or arbitrary code execution. Any application using vulnerable libvpx versions for video processing is affected.
💻 Affected Systems
- libvpx
- Applications using libvpx (Chrome, Firefox, media players, video editors)
📦 What is this software?
Libvpx by Webmproject
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Application crashes (denial of service) or memory corruption leading to unstable behavior.
If Mitigated
Controlled crashes with minimal impact if proper sandboxing and memory protections are in place.
🎯 Exploit Status
Exploitation requires crafting malicious video files or parameters, but no public exploits are currently known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.14.1
Vendor Advisory: https://g-issues.chromium.org/issues/332382766
Restart Required: Yes
Instructions:
1. Update libvpx to version 1.14.1 or later. 2. For Linux: Use package manager (apt-get update && apt-get upgrade libvpx). 3. For applications: Rebuild/reinstall with patched libvpx. 4. Restart affected applications/services.
🔧 Temporary Workarounds
Input validation
allValidate image dimensions and alignment parameters before passing to libvpx functions.
Implement parameter bounds checking in application code
Memory sandboxing
linuxRun vulnerable applications in sandboxed environments with limited privileges.
Use containers (Docker), SELinux, or AppArmor policies
🧯 If You Can't Patch
- Isolate vulnerable systems from untrusted networks and users.
- Implement strict file upload controls and scan all video files before processing.
🔍 How to Verify
Check if Vulnerable:
Check libvpx version: dpkg -l | grep libvpx (Debian/Ubuntu) or rpm -qa | grep libvpx (RHEL/CentOS).Check Version:
vpxenc --version 2>&1 | grep -i 'libvpx' || pkg-config --modversion vpxVerify Fix Applied:
Confirm version is 1.14.1 or later using version check command.📡 Detection & Monitoring
Log Indicators:
- Application crashes with libvpx in stack trace
- Memory access violation errors
