CVE-2026-34539: 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 and TIFF input can trigger a heap-buffer-overflow (HBO) in CTiffImg::WriteLine(). The issue is observable under AddressSanitizer as an out-of-bounds heap read when running iccSpecSepToTiff on a malicious .icc + .tif pair, leading to a crash during TIFF strip writing. 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)
