CVE-2020-9628
📋 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 vulnerable SDK to process DNG image 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, potentially exposing credentials, encryption keys, or other application data stored in memory.
Likely Case
Information disclosure of application memory contents, which could include partial data structures or metadata from processed images.
If Mitigated
Limited impact with proper memory protections and sandboxing, potentially only exposing non-sensitive image processing data.
🎯 Exploit Status
Exploitation requires processing a specially crafted DNG file, but no authentication is needed to trigger the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Adobe DNG SDK 1.5.1 or later
Vendor Advisory: https://helpx.adobe.com/security/products/dng-sdk/apsb20-26.html
Restart Required: No
Instructions:
1. Download DNG SDK 1.5.1 or later from Adobe's developer website. 2. Replace the vulnerable DNG SDK libraries in your application. 3. Recompile and redeploy applications using the updated SDK.
🔧 Temporary Workarounds
Input validation for DNG files
allImplement strict validation of DNG file headers and metadata before processing
Sandbox DNG processing
allIsolate DNG file processing in a separate, restricted process or container
🧯 If You Can't Patch
- Disable DNG file processing in affected applications
- Implement network segmentation to isolate systems processing DNG files
🔍 How to Verify
Check if Vulnerable:
Check if your application uses DNG SDK version 1.5 or earlier by examining linked libraries or build dependencies.Check Version:
Check the DNG SDK documentation or build configuration files for version information.Verify Fix Applied:
Verify DNG SDK version is 1.5.1 or later by checking library versions or build configuration.📡 Detection & Monitoring
Log Indicators:
- Application crashes or abnormal termination when processing DNG files
- Memory access violation errors in application logs
Network Indicators:
- Unusual patterns of DNG file uploads to affected applications
SIEM Query:
Search for application error logs containing 'access violation', 'segmentation fault', or 'out of bounds' related to DNG file processing.
