CVE-2020-9625
📋 TL;DR
Adobe DNG SDK versions 1.5 and earlier contain an out-of-bounds read vulnerability that could allow attackers to read sensitive memory contents. This affects developers and applications using the DNG SDK for processing digital negative files. Successful exploitation could lead to information disclosure.
💻 Affected Systems
- Adobe DNG Software Development Kit
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive memory contents including passwords, encryption keys, or other application data, potentially leading to complete system compromise.
Likely Case
Information disclosure of application memory contents, which could be used to bypass security controls or gather intelligence for further attacks.
If Mitigated
Limited information disclosure with no direct code execution, but still potentially revealing sensitive data.
🎯 Exploit Status
Exploitation requires specially crafted DNG files to trigger the out-of-bounds read.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: DNG SDK 1.5.1 or later
Vendor Advisory: https://helpx.adobe.com/security/products/dng-sdk/apsb20-26.html
Restart Required: Yes
Instructions:
1. Download DNG SDK 1.5.1 or later from Adobe's developer portal. 2. Replace the vulnerable DNG SDK libraries in your application. 3. Recompile and redeploy your application. 4. Restart any services using the DNG SDK.
🔧 Temporary Workarounds
Input validation for DNG files
allImplement strict validation of DNG file inputs before processing
🧯 If You Can't Patch
- Isolate applications using DNG SDK from sensitive systems and networks
- Implement strict file upload controls and scanning for DNG files
🔍 How to Verify
Check if Vulnerable:
Check the DNG SDK version used by your application. If it's 1.5 or earlier, you are vulnerable.Check Version:
Check your application's dependencies or build configuration for DNG SDK versionVerify Fix Applied:
Verify that your application uses DNG SDK version 1.5.1 or later and test with known malicious DNG files.📡 Detection & Monitoring
Log Indicators:
- Application crashes or abnormal termination when processing DNG files
- Memory access violation errors in application logs
Network Indicators:
- Unusual DNG file uploads to applications using DNG SDK
