CVE-2026-24407
📋 TL;DR
CVE-2026-24407 is an undefined behavior vulnerability in iccDEV's icSigCalcOp() function that allows attackers to manipulate ICC color profile data. Successful exploitation could lead to denial of service, data manipulation, logic bypass, or remote code execution. This affects all users of iccDEV versions 2.3.1.1 and below who process untrusted ICC profiles.
💻 Affected Systems
- iccDEV
📦 What is this software?
Iccdev by Color
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with full system compromise through malicious ICC profile processing
Likely Case
Denial of service or application crashes when processing malformed ICC profiles
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 systems
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-m6gx-93cp-4855
Restart Required: Yes
Instructions:
1. Update iccDEV to version 2.3.1.2 or later. 2. Rebuild any applications using iccDEV libraries. 3. Restart affected services.
🔧 Temporary Workarounds
Input validation for ICC profiles
allImplement strict validation of ICC profile files before processing
Sandbox profile processing
allIsolate ICC profile processing in restricted environments
🧯 If You Can't Patch
- Implement strict file upload restrictions for ICC profiles
- Disable automatic processing of untrusted ICC profiles
🔍 How to Verify
Check if Vulnerable:
Check iccDEV version using package manager or by examining installed librariesCheck Version:
iccdev --version or check package manager (apt list iccdev, yum list iccdev, etc.)Verify Fix Applied:
Verify iccDEV version is 2.3.1.2 or higher and test with known safe ICC profiles📡 Detection & Monitoring
