CVE-2026-31793
📋 TL;DR
A segmentation fault vulnerability in iccDEV's CIccCalculatorFunc::ApplySequence() function allows denial of service through invalid pointer reads. This affects applications using iccDEV libraries for ICC color profile processing. The vulnerability can crash applications that process malicious or malformed ICC color profiles.
💻 Affected Systems
- iccDEV library and tools
⚠️ 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).

- Consider updating to the latest version as a precaution
⚠️ 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 malformed ICC color profiles, requiring restart of affected software.
If Mitigated
Minimal impact with proper input validation and error handling in place, though application may still experience crashes.
🎯 Exploit Status
Exploitation requires processing a malicious ICC profile file, typically through user interaction or automated processing.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.3.1.5
Vendor Advisory: https://github.com/InternationalColorConsortium/iccDEV/security/advisories/GHSA-vgr5-3xqx-vcqx
Restart Required: Yes
Instructions:
1. Download iccDEV v2.3.1.5 from GitHub releases. 2. Recompile and reinstall iccDEV libraries. 3. Recompile or restart applications using iccDEV. 4. Verify version with iccDEV tools.
🔧 Temporary Workarounds
Input Validation
allImplement strict validation of ICC profile files before processing
Process Isolation
allRun ICC profile processing in isolated containers or sandboxes
🧯 If You Can't Patch
- Implement application-level error handling to catch segmentation faults and restart gracefully
- Restrict processing of untrusted ICC profiles and implement file type validation
🔍 How to Verify
Check if Vulnerable:
Check iccDEV library version or check if application crashes when processing malformed ICC profilesCheck Version:
iccversion or check library version in application outputVerify Fix Applied:
Test with known malformed ICC profiles that previously caused crashes📡 Detection & Monitoring
Log Indicators:
- Segmentation fault errors
- Application crash logs
- Unexpected process termination
Network Indicators:
- None - local file processing vulnerability
SIEM Query:
process.name: "*" AND event.type: "crash" AND error.message: "segmentation fault"🔗 References
