Executive Summary

This vulnerability exists in EmberZNet version 9.0.2 and earlier. It involves malformed Color Control messages that can cause the software to assert and terminate the process unexpectedly.

These malformed messages must originate from a device that has already joined the network, and only devices that support the Color Control cluster are potentially affected.
