Stack Overflow in iccDEV ICC Profile Processing Causes Crash

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 overflow (SO) in SIccCalcOp::ArgsUsed(). The issue is observable under AddressSanitizer as a stack-overflow when iccApplyProfiles processes a malicious profile, with the crash occurring while computing argument usage during calculator underflow/overflow checks. This issue has been patched in version 2.3.1.6.

Attack-Flow Graph

Impact Analysis

The vulnerability can cause a stack overflow resulting in a crash of the application using the iccDEV libraries when processing a malicious ICC profile. According to the CVSS score, the impact is on availability (A:H), meaning it can cause denial of service by crashing the application. There is no impact on confidentiality or integrity.

Executive Summary

This vulnerability exists in iccDEV, a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a specially crafted ICC profile can cause a stack overflow in the function SIccCalcOp::ArgsUsed(). This happens when the iccApplyProfiles function processes a malicious profile, leading to a crash during the calculation of argument usage related to underflow or overflow checks in the calculator.

Detection Guidance

This vulnerability can be detected by observing crashes or stack overflow errors when processing ICC profiles with vulnerable versions of iccDEV prior to 2.3.1.6. Specifically, running iccApplyProfiles on a crafted malicious ICC profile under AddressSanitizer can reveal a stack overflow in SIccCalcOp::ArgsUsed().

There are no specific commands provided to detect this vulnerability on your system or network.

Mitigation Strategies

The immediate step to mitigate this vulnerability is to upgrade iccDEV to version 2.3.1.6 or later, where the stack overflow issue has been patched.
