CVE-2025-64894
📋 TL;DR
CVE-2025-64894 is an integer overflow vulnerability in DNG SDK versions 1.7.0 and earlier that allows attackers to cause denial-of-service by tricking users into opening malicious files. This affects applications and systems that process DNG (Digital Negative) image files using the vulnerable SDK. The vulnerability requires user interaction through file opening.
💻 Affected Systems
- Adobe DNG SDK
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete application crash leading to denial-of-service, potentially disrupting workflows that rely on DNG file processing.
Likely Case
Application becomes unresponsive or crashes when processing specially crafted DNG files, requiring restart.
If Mitigated
No impact if malicious files are prevented from reaching users or if patched version is used.
🎯 Exploit Status
Exploitation requires user to open malicious DNG file. No authentication bypass needed beyond file access.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.7.1 or later
Vendor Advisory: https://helpx.adobe.com/security/products/dng-sdk/apsb25-118.html
Restart Required: Yes
Instructions:
1. Download DNG SDK version 1.7.1 or later from Adobe. 2. Replace vulnerable SDK files with patched version. 3. Recompile any applications using the SDK. 4. Restart affected applications/services.
🔧 Temporary Workarounds
File type restriction
allBlock or restrict DNG file processing in vulnerable applications
User awareness training
allTrain users not to open DNG files from untrusted sources
🧯 If You Can't Patch
- Implement application whitelisting to prevent execution of vulnerable DNG processing components
- Use file integrity monitoring to detect unauthorized DNG file processing attempts
🔍 How to Verify
Check if Vulnerable:
Check DNG SDK version in use. If version is 1.7.0 or earlier, system is vulnerable.Check Version:
Check SDK documentation or build configuration for version informationVerify Fix Applied:
Verify DNG SDK version is 1.7.1 or later and test with known safe DNG files.📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing DNG files
- Unexpected termination of DNG-related processes
Network Indicators:
- Unusual DNG file downloads from untrusted sources
SIEM Query:
EventID: Application Crash AND ProcessName contains 'dng' OR FileExtension: '.dng'
