CVE-2025-64783
📋 TL;DR
CVE-2025-64783 is an integer overflow vulnerability in Adobe DNG SDK versions 1.7.0 and earlier that allows arbitrary code execution when a user opens a malicious DNG file. This affects any application or system that uses the vulnerable DNG SDK for processing digital negative files. The attacker gains the same privileges as the current user.
💻 Affected Systems
- Adobe DNG SDK
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the same privileges as the user, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation or malware installation on the affected system, with potential for data exfiltration or system disruption.
If Mitigated
Limited impact due to user account restrictions, with potential for local file corruption or denial of service.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file). The vulnerability is in file parsing logic, making reliable exploitation dependent on specific memory layouts.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.8.0 or later
Vendor Advisory: https://helpx.adobe.com/security/products/dng-sdk/apsb25-118.html
Restart Required: Yes
Instructions:
1. Download DNG SDK version 1.8.0 or later from Adobe's developer website. 2. Replace the vulnerable SDK files with the updated version. 3. Recompile any applications using the SDK. 4. Restart systems using the updated applications.
🔧 Temporary Workarounds
Restrict DNG file processing
allBlock or restrict processing of DNG files from untrusted sources
Application sandboxing
allRun applications using DNG SDK in restricted environments or containers
🧯 If You Can't Patch
- Implement application allowlisting to prevent unauthorized applications from running
- Use endpoint protection with behavioral analysis to detect exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check the version of DNG SDK used by applications. If version is 1.7.0 or earlier, the system is vulnerable.Check Version:
Check the SDK header files or documentation for version information. For compiled applications, check vendor documentation or use strings command on binaries: strings application_binary | grep -i dngVerify Fix Applied:
Verify that DNG SDK version is 1.8.0 or later and that applications have been recompiled with the updated SDK.📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing DNG files
- Unusual process creation from DNG processing applications
- Memory access violations in application logs
Network Indicators:
- Unexpected outbound connections from DNG processing applications
- File downloads of DNG files from untrusted sources
SIEM Query:
Process creation where parent process is DNG-related application AND (command line contains .dng OR file extension is .dng)
