CVE-2026-34540
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.
Does this matter?
Lower severity and a low EPSS score (0.16%). Track it; it rarely justifies an emergency change on its own.
Description
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.

This issue has been patched in version 2.3.1.6.
