CVE-2026-21673

The iccDEV library versions 2.3.1.1 and below have a heap buffer overflow vulnerability in the CIccTagXmlSegmentedCurve::ToXml() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have undefined behavior in the CIccTagXmlSegmentedCurve::ToXml() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have undefined behavior and null pointer dereference in the CIccProfileXml::ParseBasic() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have undefined behavior and null pointer dereference in the CIccTagXmlFloatNum<>::ParseXml() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have undefined behavior in the icSigCalcOp() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have a heap buffer overflow vulnerability in the CIccTagNamedColor2::SetSize() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have a heap buffer overflow vulnerability in the CIccMpeCalculator::Read() function. This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have a null pointer dereference and undefined behavior vulnerability in CIccXmlArrayType(). This occurs when user-controllable input is unsafely incorporated into ICC profile data or other structured binary blobs. Successful exploitation may allow an attacker to perform DoS, manipulate data, bypass application logic and code execution. This issue has been fixed in version 2.3.1.2.

The iccDEV library versions 2.3.1.1 and below have an integer overflow vulnerability in icValidateStatus CIccProfile::CheckHeader() when user-controllable input is incorporated into profile data unsafely. Tampering with tag tables, offsets, or size fields can trigger parsing errors, memory corruption, or DoS, potentially enabling arbitrary code execution or bypassing application logic. This issue has been fixed in version 2.3.1.2.

The iccDEV library before version 2.3.1.2 contains a heap-based buffer overflow vulnerability in the SIccCalcOp::Describe() function in IccProfLib/IccMpeCalc.cpp. This affects users who process ICC color profiles.
