Unknown Unknown - Not Provided
Type Confusion in iccDEV ICC Profile Processing Library

Publication date: 2026-01-07

Last updated on: 2026-01-07

Assigner: GitHub, Inc.

Description
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of International Color Consortium (ICC) color management profiles. Versions prior to 2.3.1.2 have a Type Confusion vulnerability in `CIccSegmentedCurveXml::ToXml()` at `IccXML/IccLibXML/IccMpeXml.cpp`. This vulnerability affects users of the iccDEV library who process ICC color profiles. Version 2.3.1.2 contains a patch. No known workarounds are available.

Executive Summary

This vulnerability is a Type Confusion issue in the iccDEV library, specifically in the function CIccSegmentedCurveXml::ToXml() within the IccXML/IccLibXML/IccMpeXml.cpp file. It affects versions prior to 2.3.1.2 and involves improper handling of ICC color management profiles, which can lead to unexpected behavior or exploitation.

Impact Analysis

The vulnerability has a high severity with a CVSS base score of 8.8, indicating it can be exploited remotely without privileges but requires user interaction. It can lead to high impact on confidentiality, integrity, and availability, meaning attackers could potentially execute arbitrary code, cause data corruption, or disrupt services when processing ICC color profiles using the affected iccDEV library.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to upgrade the iccDEV library to version 2.3.1.2 or later, which contains the patch for the Type Confusion vulnerability. No known workarounds are available.
