CVE-2026-34535: Color iccdev heap-based buffer overflow vulnerability

Color · Iccdev

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Prior to version 2.3.1.6, a crafted ICC profile can trigger a segmentation fault (SEGV) in CIccTagArray::Cleanup(). The issue is observable under UBSan/ASan as misaligned member access / misaligned pointer loads followed by an invalid read leading to process crash when running iccRoundTrip on a malicious profile. This issue has been patched in version 2.3.1.6.
