CVE-2026-34552 iccDEV空指针拒绝服务漏洞

// PoC for CVE-2026-34552: Null Pointer Dereference in iccDEV // This code demonstrates the concept of the vulnerability. // Requires linking against the vulnerable iccDEV library version < 2.3.1.6 #include <iostream> #include "IccTagLut.h" // Assuming header file exists int main() { std::cout << "[+] Attempting to trigger CVE-2026-34552..." << std::endl; // Simulation of the vulnerable condition // In the real scenario, a malformed ICC profile or specific API call // leads to a null 'CIccApplyCLUT' object inside IccTagLut. CIccApplyCLUT* nullObject = nullptr; try { // This mimics the code path in IccTagLut.cpp causing the crash // Direct member access through null pointer -> Undefined Behavior -> Crash // (Actual trigger depends on internal library usage) if (nullObject == nullptr) { std::cout << "[!] Triggering null pointer access..." << std::endl; // The following line would cause the crash in the vulnerable version // nullObject->Process(); } } catch (...) { std::cout << "[!] Exception caught." << std::endl; } return 0; }
