CVE-2026-34540: Color Iccdev

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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 heap-buffer-overflow (HBO) in icMemDump() when iccDumpProfile attempts to dump/describe malformed tag contents. 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.

Affected products

• Color Iccdev: before 2.3.1.6 (fixed in 2.3.1.6)
