Buffer overflow in Color Iccdev
CVE-2026-34540
iccDEV provides a set of libraries and tools for working with ICC color management profiles.

The issue is observable under AddressSanitizer as an out-of-bounds heap read in icMemDump(...) at IccProfLib/IccUtil.cpp:1002, reachable via CIccTagUnknown::Describe(). This issue has been patched in version 2.3.1.6.
