CVE-2026-34542: CWE-121: Stack-based Buffer Overflow in InternationalColorConsortium iccDEV
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.
AI Analysis
Technical Summary
The iccDEV library, used for handling ICC color management profiles, contains a stack-based buffer overflow vulnerability (CWE-121) in the CIccCalculatorFunc::Apply() function. This occurs when a specially crafted ICC profile is processed through iccApplyNamedCmm, triggering a 4-byte write overflow on the stack in IccProfLib/IccMpeCalc.cpp at line 3873. The issue arises during the MPE calculator's curve set initialization path. This vulnerability affects versions prior to 2.3.1.6 and has been patched in that version.
Potential Impact
Successful exploitation of this vulnerability can cause a stack-based buffer overflow leading to application crashes or potential denial of service. The CVSS vector indicates local attack vector with low complexity and no privileges or user interaction required. There is no confidentiality or integrity impact reported. No known exploits in the wild have been identified.
Mitigation Recommendations
Upgrade iccDEV to version 2.3.1.6 or later, where this stack-based buffer overflow vulnerability has been fixed. No other mitigation is indicated by the vendor advisory.
