CVE-2026-24406
📋 TL;DR
CVE-2026-24406 is a heap buffer overflow vulnerability in iccDEV's CIccTagNamedColor2::SetSize() function that allows attackers to execute arbitrary code or cause denial of service. This affects any application using iccDEV libraries for ICC color profile processing. Users of iccDEV versions 2.3.1.1 and below are vulnerable when processing malicious ICC profiles.
💻 Affected Systems
- iccDEV library and any software using iccDEV for ICC color profile processing
📦 What is this software?
Iccdev by Color
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with attacker gaining full control of the affected system, potentially leading to data theft, system compromise, or lateral movement.
Likely Case
Application crash (DoS) or memory corruption leading to data manipulation and potential privilege escalation.
If Mitigated
Application crash with no data loss if proper sandboxing and memory protections are in place.
🎯 Exploit Status
Exploitation requires crafting malicious ICC profiles. The vulnerability is in a core library function, making exploitation feasible but requiring specific knowledge of ICC profile structure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-h9h3-45cm-j95f
Restart Required: Yes
Instructions:
1. Update iccDEV to version 2.3.1.2 or later. 2. Recompile any applications using iccDEV libraries. 3. Restart affected applications/services. 4. Test color profile functionality.
🔧 Temporary Workarounds
Input Validation for ICC Profiles
allImplement strict validation of ICC profile files before processing
# Implement file validation in application code
# Reject malformed or suspicious ICC profiles
Memory Protection Controls
allEnable ASLR, DEP, and other memory protection mechanisms
# Linux: sysctl -w kernel.randomize_va_space=2
# Windows: Enable Data Execution Prevention (DEP)
🧯 If You Can't Patch
- Isolate systems using iccDEV behind firewalls and restrict network access
- Implement application whitelisting to prevent execution of unauthorized code
🔍 How to Verify
Check if Vulnerable:
Check iccDEV version: iccDEV --version or examine linked library versions in applicationsCheck Version:
iccDEV --version 2>&1 | grep -i versionVerify Fix Applied:
Verify iccDEV version is 2.3.1.2 or higher and test with known ICC profile processing📡 Detection & Monitoring
Log Indicators:
- Application crashes with segmentation faults
- Memory access violation errors
- Unexpected process termination
Network Indicators:
- Unusual network connections from color management applications
- Suspicious file uploads to ICC profile processing services
