CVE-2026-22255
📋 TL;DR
A heap-buffer-overflow vulnerability in iccDEV's CIccCLUT::Init() function allows attackers to 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 applications like image processing software, design tools, or color management systems.
💻 Affected Systems
- iccDEV library
- Any software 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 (denial of service) with potential for limited code execution in the application context
If Mitigated
Application crash without code execution if memory protections like ASLR/DEP are effective
🎯 Exploit Status
Exploitation requires crafting malicious ICC profiles and getting them processed by vulnerable software
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-qv2w-mq3g-73gv
Restart Required: Yes
Instructions:
1. Update iccDEV library to version 2.3.1.2 or later. 2. Rebuild any applications using the library. 3. Restart affected services/applications.
🧯 If You Can't Patch
- Implement strict file validation for ICC profiles before processing
- Isolate color profile processing to sandboxed environments
🔍 How to Verify
Check if Vulnerable:
Check linked library version: ldd /path/to/application | grep iccDEV or check package manager for iccDEV versionCheck Version:
pkg-config --modversion iccdev 2>/dev/null || echo "Check application dependencies for iccDEV version"Verify Fix Applied:
Verify iccDEV version is 2.3.1.2 or higher: pkg-config --modversion iccdev or check library file version📡 Detection & Monitoring
Log Indicators:
- Application crashes with segmentation faults in color processing functions
- Memory corruption errors in application logs
Network Indicators:
- Unusual ICC profile uploads to web applications
- Large or malformed ICC files in network traffic
SIEM Query:
