CVE-2023-46867Network attack vector

Application crash via null curve pointer dereference

Published Oct 30, 2023 · Updated Sep 9, 2024

NULL pointer dereference in DemoIccMAX 79ecb74 allows context-dependent attackers to crash profile-processing applications. CIccXformMatrixTRC::GetCurve at IccCmm.cpp line 5240 reads through a null pointer while CIccXformMatrixTRC::Begin initializes a profile transform. Exploitation requires user interaction and an input that reaches profile evaluation; the upstream report does not disclose the exact triggering input.
