CVE-2026-24405
📋 TL;DR
A heap buffer overflow vulnerability in iccDEV's CIccMpeCalculator::Read() function allows attackers to execute arbitrary code or cause denial of service by providing malicious ICC profile data. This affects all applications using iccDEV libraries version 2.3.1.1 or earlier for color management. Users processing untrusted ICC profiles are particularly vulnerable.
💻 Affected Systems
- iccDEV library and tools
- Applications using iccDEV for ICC profile processing
📦 What is this software?
Iccdev by Color
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application processing the ICC profile, potentially leading to complete system compromise.
Likely Case
Application crash (denial of service) or limited data manipulation when processing malformed ICC profiles.
If Mitigated
No impact if proper input validation and sandboxing prevent malicious profile processing.
🎯 Exploit Status
Exploitation requires crafting malicious ICC profiles, but no public proof-of-concept is available yet.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.2
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-2r5c-5w66-47vv
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 or applications.
🔧 Temporary Workarounds
Input validation for ICC profiles
allImplement strict validation of ICC profile data before processing with iccDEV libraries.
Sandbox ICC profile processing
allRun ICC profile processing in isolated containers or sandboxes to limit potential damage.
🧯 If You Can't Patch
- Restrict processing of ICC profiles to trusted sources only.
- Implement network segmentation to isolate systems using vulnerable iccDEV versions.
🔍 How to Verify
Check if Vulnerable:
Check if your application uses iccDEV version 2.3.1.1 or earlier by examining dependencies or running 'iccDEV --version' if available.Check Version:
iccDEV --versionVerify Fix Applied:
Confirm iccDEV version is 2.3.1.2 or later and test with known safe ICC profiles.📡 Detection & Monitoring
