CVE-2025-70968
📋 TL;DR
FreeImage 3.18.0 contains a use-after-free vulnerability in the TARGA image parser that allows attackers to execute arbitrary code or cause denial of service. This affects any application that uses FreeImage to process untrusted TARGA images. Developers and systems using FreeImage libraries are at risk.
💻 Affected Systems
- FreeImage
📦 What is this software?
Freeimage by Freeimage Project
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application processing the image, potentially leading to complete system compromise.
Likely Case
Application crash (denial of service) when processing malicious TARGA files, with potential for code execution in some configurations.
If Mitigated
Application crash without code execution if memory protections like ASLR are effective.
🎯 Exploit Status
Proof-of-concept crash code is publicly available. The use-after-free nature makes reliable exploitation more complex but possible with heap manipulation techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Monitor FreeImage project for security updates. 2. Consider temporary workarounds. 3. Recompile applications with patched library when available.
🔧 Temporary Workarounds
Disable TARGA plugin
allRemove or disable FreeImage's TARGA plugin to prevent processing of TARGA files
rm /path/to/FreeImage/Plugins/TARGA.*
Remove TARGA from plugin compilation
Input validation
allReject TARGA files at application level before passing to FreeImage
Implement file type checking before FreeImage processing
🧯 If You Can't Patch
- Implement strict input validation to reject TARGA files at network boundaries
- Run vulnerable applications with reduced privileges and memory protection mechanisms enabled
🔍 How to Verify
Check if Vulnerable:
Check if application links against FreeImage 3.18.0 and processes image filesCheck Version:
Check application dependencies or FreeImage library version (varies by platform)Verify Fix Applied:
Test with proof-of-concept TARGA file to confirm crash no longer occurs📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing image files
- Memory access violation errors
- Unexpected process termination
Network Indicators:
- Unusual TARGA file uploads to services
- Multiple failed image processing attempts
