CVE-2023-46866Public exploitNetwork attack vector

Application crash via unchecked interpolation indexes

Published Oct 30, 2023 · Updated Sep 9, 2024

Heap-buffer overflow in International Color Consortium DemoIccMAX 79ecb74 allows remote attackers to crash applications through crafted ICC profile data. CIccCLUT::Interp3d calculates interpolation indexes when m_nNumPoints multiplied by m_nOutput is zero, then reads beyond the unallocated or zero-sized m_pData array. Exploitation requires user interaction to process attacker-controlled profile data; the demonstrated consequence is an application crash.
