CVE-2025-54874
📋 TL;DR
This vulnerability in OpenJPEG allows an attacker to write data beyond allocated heap memory boundaries when processing specially crafted JPEG 2000 files. This can lead to remote code execution, denial of service, or information disclosure. Any application using vulnerable OpenJPEG versions to process untrusted JPEG 2000 files is affected.
💻 Affected Systems
- OpenJPEG
- Applications using OpenJPEG library (e.g., OpenCV, image processing tools)
📦 What is this software?

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application processing the malicious file, potentially leading to complete system compromise.
Likely Case
Application crash (denial of service) or memory corruption leading to unpredictable behavior.
If Mitigated
Limited impact if proper input validation and sandboxing prevent malicious file processing.
🎯 Exploit Status
Exploitation requires crafting a malformed JPEG 2000 file; no public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.5.4 or later
Vendor Advisory: https://github.com/uclouvain/openjpeg/commit/f809b80c67717c152a5ad30bf06774f00da4fd2d
Restart Required: Yes
Instructions:
1. Update OpenJPEG to version 2.5.4 or later. 2. Rebuild any applications linked against OpenJPEG. 3. Restart affected services.
🔧 Temporary Workarounds
Disable JPEG 2000 processing
allConfigure applications to reject or not process JPEG 2000 files.
Input validation
allImplement strict file validation before passing to OpenJPEG.
🧯 If You Can't Patch
- Isolate systems processing JPEG 2000 files in restricted network segments.
- Implement application sandboxing to limit potential damage from exploitation.
🔍 How to Verify
Check if Vulnerable:
Check OpenJPEG version with 'opj_decompress -v' or examine library version in linked applications.Check Version:
opj_decompress -v 2>&1 | grep VersionVerify Fix Applied:
Confirm OpenJPEG version is 2.5.4 or later and test with known malformed JPEG 2000 files.📡 Detection & Monitoring
