CVE-2026-21682
📋 TL;DR
CVE-2026-21682 is a heap buffer overflow vulnerability in iccDEV's CIccXmlArrayType::ParseText() function that allows attackers to execute arbitrary code or cause denial of service by processing malicious ICC color profiles. This affects all applications using iccDEV libraries for color management. Users of affected versions are vulnerable when processing untrusted ICC profiles.
💻 Affected Systems
- iccDEV library
- Applications using iccDEV for ICC profile processing
📦 What is this software?
Iccdev by Color
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or ransomware deployment.
Likely Case
Application crash or denial of service affecting color processing functionality.
If Mitigated
Limited impact with proper input validation and memory protection mechanisms in place.
🎯 Exploit Status
Exploitation requires crafting malicious ICC profiles and getting them processed by vulnerable applications. No public exploits are currently known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-jq9m-54gr-c56c
Restart Required: Yes
Instructions:
1. Update iccDEV to version 2.3.1.2 or later. 2. Rebuild any applications using iccDEV with the updated library. 3. Restart affected applications/services. 4. Test color processing functionality after update.
🔧 Temporary Workarounds
No known workarounds
allThe vendor advisory states no workarounds are available. Patching is the only solution.
🧯 If You Can't Patch
- Implement strict input validation for ICC profile files before processing
- Isolate color processing applications in restricted environments with limited privileges
🔍 How to Verify
Check if Vulnerable:
Check if your application uses iccDEV library version < 2.3.1.2. Review application dependencies and linked libraries.Check Version:
For Linux: ldd <application> | grep iccDEV; For compiled applications: check build configuration or dependency manifestsVerify Fix Applied:
Verify iccDEV version is 2.3.1.2 or later. Test with known ICC profiles to ensure color processing works correctly.📡 Detection & Monitoring
Log Indicators:
- Application crashes during ICC profile processing
- Memory access violation errors in application logs
- Segmentation faults in color management components
Network Indicators:
- Unusual uploads of ICC profile files to web applications
- Multiple failed attempts to process color profiles
SIEM Query:
