CVE-2026-25503 – A type confusion vulnerability in iccDEV allows... (How to Fix)

Q: What is the severity of CVE-2026-25503?

CVE-2026-25503 has a CVSS score of 7.1 (HIGH). A type confusion vulnerability in iccDEV allows malformed ICC color profiles to trigger undefined behavior when loading invalid icImageEncodingType values, causing denial of service. This affects all applications using iccDEV libraries prior to version 2.3.1.2 for color management operations.

📋 TL;DR

A type confusion vulnerability in iccDEV allows malformed ICC color profiles to trigger undefined behavior when loading invalid icImageEncodingType values, causing denial of service. This affects all applications using iccDEV libraries prior to version 2.3.1.2 for color management operations.

💻 Affected Systems

Products:

iccDEV library and dependent applications

Versions: All versions prior to 2.3.1.2

Operating Systems: All platforms using iccDEV

Default Config Vulnerable: ⚠️ Yes

Notes: Any application using iccDEV libraries to parse ICC color profiles is vulnerable.

⚠️ Manual Verification Required

⚠️ Risk & Real-World Impact

🔴

Worst Case

Application crash leading to denial of service, potentially disrupting color-critical workflows in design, printing, or imaging applications.

🟠

Likely Case

Application instability or crashes when processing malicious or corrupted ICC color profiles.

🟢

If Mitigated

Minimal impact with proper input validation and updated libraries.

🌐 Internet-Facing: MEDIUM - Applications accepting user-uploaded ICC profiles could be targeted.

🏢 Internal Only: LOW - Requires processing of malicious ICC files, which is less likely in controlled environments.

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ⚠️ Yes

Complexity: LOW

Exploitation requires providing a malformed ICC profile file to vulnerable applications.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.3.1.2

Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-pf84-4c7q-x764

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

all

Implement strict validation of ICC profile files before processing

Restrict file uploads

all

Limit ICC profile uploads to trusted sources only

🧯 If You Can't Patch

Implement application-level input validation for ICC profile files
Isolate color management services and restrict file processing to trusted sources

🔍 How to Verify

Check if Vulnerable:

Check if applications use iccDEV library version < 2.3.1.2

Check Version:

Check library version in build configuration or runtime dependency checks

Verify Fix Applied:

Verify iccDEV version is 2.3.1.2 or higher and applications have been rebuilt

📡 Detection & Monitoring

Log Indicators:

Application crashes or abnormal terminations when processing ICC files
Error messages related to icImageEncodingType or ICC profile parsing

Network Indicators:

Unusual ICC file uploads to color management services

SIEM Query:

Application logs containing 'iccDEV', 'ICC profile', or 'icImageEncodingType' errors
