CVE-2025-53644
📋 TL;DR
OpenCV versions 4.10.0 and 4.11.0 contain an uninitialized pointer vulnerability (CWE-457) that allows arbitrary heap buffer writes when processing specially crafted JPEG images. This can lead to remote code execution or application crashes. Any system or application using these vulnerable OpenCV versions for JPEG image processing is affected.
💻 Affected Systems
- OpenCV
📦 What is this software?
Opencv by Opencv
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the OpenCV process, potentially leading to full system compromise.
Likely Case
Application crash (denial of service) or memory corruption leading to unstable behavior.
If Mitigated
Limited impact if proper input validation and sandboxing are implemented.
🎯 Exploit Status
Exploitation requires crafting a malicious JPEG file and getting it processed by vulnerable OpenCV code. No public exploit code is known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.12.0
Vendor Advisory: https://github.com/opencv/opencv/releases/tag/4.12.0
Restart Required: Yes
Instructions:
1. Upgrade OpenCV to version 4.12.0 or later. 2. Recompile any applications using OpenCV with the updated library. 3. Restart affected services or applications.
🔧 Temporary Workarounds
Disable JPEG processing
allTemporarily disable JPEG image processing in applications using OpenCV until patching is complete.
Application-specific configuration changes required
Input validation
linuxImplement strict validation of JPEG files before passing them to OpenCV for processing.
Use external tools like 'file' command or libmagic to verify JPEG integrity
🧯 If You Can't Patch
- Implement network segmentation to isolate systems using vulnerable OpenCV versions.
- Deploy application allowlisting to prevent execution of unauthorized code.
🔍 How to Verify
Check if Vulnerable:
Check OpenCV version with 'pkg-config --modversion opencv4' or examine linked library versions in applications.
Check Version:
pkg-config --modversion opencv4
Verify Fix Applied:
Confirm OpenCV version is 4.12.0 or higher using version check commands.
📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing JPEG images
- Memory access violation errors in application logs
Network Indicators:
- Unusual outbound connections from applications processing images
- Large volumes of JPEG uploads to vulnerable endpoints
