Sources and claim methodology

Upstream source description

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.
