CVE-2026-21688
📋 TL;DR
A type confusion vulnerability in iccDEV's SIccCalcOp::ArgsPushed() function allows attackers to potentially execute arbitrary code or cause denial of service by processing malicious ICC color profiles. This affects all users of iccDEV library versions before 2.3.1.2 who handle ICC color profiles in their applications.
💻 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 sandboxing of profile processing
🎯 Exploit Status
Exploitation requires crafting malicious ICC profiles and getting them processed by vulnerable applications
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-3r2x-j7v3-pg6f
Restart Required: Yes
