Stack Buffer Overflow in iccDEV ICC Profile Processing

Publication date: 2026-03-31

Last updated on: 2026-04-20

Assigner: GitHub, Inc.

Description
iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger a stack-buffer-overflow (SBO) in CIccCalculatorFunc::Apply() when processed via iccApplyNamedCmm. Under AddressSanitizer, the failure is reported as a 4-byte write stack-buffer-overflow in IccProfLib/IccMpeCalc.cpp:3873, reachable through the MPE calculator / curve set initialization path. This issue has been patched in version 2.3.1.6.

Executive Summary

This vulnerability exists in iccDEV, a set of libraries and tools for working with ICC color management profiles. Before version 2.3.1.6, a specially crafted ICC profile can cause a stack-buffer-overflow (SBO) in the function CIccCalculatorFunc::Apply() when processed using iccApplyNamedCmm. Specifically, this overflow occurs as a 4-byte write beyond the stack buffer in the IccProfLib/IccMpeCalc.cpp file at line 3873, triggered through the MPE calculator or curve set initialization path. The issue has been fixed in version 2.3.1.6.

Impact Analysis

The vulnerability can lead to a stack-buffer-overflow, which may cause a program crash or potentially allow an attacker to execute arbitrary code or disrupt the normal operation of the software. Since the CVSS score rates the impact on availability as high (A:H) but no impact on confidentiality or integrity, the primary risk is denial of service or application instability when processing malicious ICC profiles.

Mitigation Strategies

The vulnerability has been patched in iccDEV version 2.3.1.6. To mitigate this vulnerability, you should upgrade your iccDEV libraries and tools to version 2.3.1.6 or later.
