Summary

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Versions prior to 2.3.2.1 have a `CIccEmbedIO::Read8()` size_t underflow. The issue arises due to an embedded-profile read defect when parsing ICC profiles containing `icSigEmbeddedV5ProfileTag` data with `icSigEmbeddedProfileType` payloads. Version 2.3.2.1 patches the issue. No known workarounds are available.

Inferred packages

No advisory lists a package for this vulnerability yet. The CVE names these as products and links their GitHub repository, and the package registry names the same repository, so they are probably the affected packages. Low confidence: the versions are the CVE’s own for the product, and a stack check reports the package as unchecked when there are none.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of InternationalColorConsortium/iccDEV published their own advisory on GitHub. Reviewed sources take precedence over it.
