CVE-2026-30987 – A stack buffer overflow vulnerability in iccDEV... (How to Fix)

Q: What is the severity of CVE-2026-30987?

CVE-2026-30987 has a CVSS score of 7.8 (HIGH). A stack buffer overflow vulnerability in iccDEV's CIccTagNum<>::GetValues() function allows attackers to corrupt stack memory or cause crashes. This affects all systems using iccDEV libraries prior to version 2.3.1.5 for ICC color profile processing. Applications that parse untrusted ICC profiles are particularly vulnerable.

📋 TL;DR

A stack buffer overflow vulnerability in iccDEV's CIccTagNum<>::GetValues() function allows attackers to corrupt stack memory or cause crashes. This affects all systems using iccDEV libraries prior to version 2.3.1.5 for ICC color profile processing. Applications that parse untrusted ICC profiles are particularly vulnerable.

💻 Affected Systems

Products:

iccDEV library and any software using iccDEV for ICC color profile processing

Versions: All versions prior to 2.3.1.5

Operating Systems: All platforms where iccDEV is used (Linux, Windows, macOS, etc.)

Default Config Vulnerable: ⚠️ Yes

Notes: Vulnerability is triggered when processing ICC profiles with the CIccTagNum<>::GetValues() function

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:

Review the CVE details at NVD
Check vendor security advisories for your specific version
Test if the vulnerability is exploitable in your environment
Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete system compromise if the overflow can be controlled to execute arbitrary code

🟠

Likely Case

Application crashes (denial of service) or memory corruption leading to unstable behavior

🟢

If Mitigated

Controlled crashes with minimal impact if proper memory protections (ASLR, stack canaries) are enabled

🌐 Internet-Facing: MEDIUM - Requires processing of malicious ICC profiles, which could be delivered via web uploads or email attachments

🏢 Internal Only: LOW - Typically requires user interaction or specific application workflows to trigger

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ✅ No

Complexity: MEDIUM - Requires crafting malicious ICC profiles and triggering specific code paths

Exploitation requires the application to process attacker-controlled ICC profiles

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.3.1.5

Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-fj57-gfhq-rjqr

Restart Required: Yes

Instructions:

1. Identify applications using iccDEV
2. Update iccDEV to version 2.3.1.5 or later
3. Rebuild applications with updated library
4. Restart affected services

🔧 Temporary Workarounds

Input validation for ICC profiles

all

Implement strict validation of ICC profile inputs before processing

Memory protection hardening

all

Enable ASLR, stack canaries, and other memory protection mechanisms

gcc -fstack-protector-all -D_FORTIFY_SOURCE=2 (Linux)
Enable DEP and ASLR in Windows security settings

🧯 If You Can't Patch

Implement strict file upload filtering to block untrusted ICC profiles
Isolate applications using iccDEV in restricted network segments

🔍 How to Verify

Check if Vulnerable:

Check iccDEV version with: iccDEV --version or examine linked libraries in applications

Check Version:

iccDEV --version 2>&1 | grep -i version

Verify Fix Applied:

Confirm version is 2.3.1.5 or later and test with known ICC profile processing

📡 Detection & Monitoring

Log Indicators:

Application crashes with segmentation faults
Memory corruption errors in application logs
Unexpected termination of ICC processing services

Network Indicators:

Unusual ICC profile uploads to web applications
Multiple failed ICC processing attempts

SIEM Query:

event.category:process AND process.name:(*icc* OR *color*) AND event.outcome:failure
