Alert meAnalysisAIv1 – Mar 12, 2026
iccDEV versions before 2.3.1.2 contain undefined behavior in the CIccTagLut16::Read() function that allows attackers to cause denial of service or data corruption when processing specially crafted ICC color profiles. The vulnerability requires user interaction to exploit and affects applications using the iccDEV library to handle color management profiles. Public exploit code exists for this issue, though a patch is available in version 2.3.1.2.
Earlier versions of this analysis (1)
