**Name of the Vulnerable Software and Affected Versions** Philips Hue Bridge (affected versions not specified) **Description** A heap-based buffer overflow exists in the custom command handler of the Zigbee stack. This issue occurs due to insufficient validation of data size before it is copied into a fixed-size heap buffer during the processing of custom Zigbee ZCL (Zigbee Cluster Library) frames within the Model Info download functionality. Network-adjacent attackers can exploit this flaw to execute arbitrary code in the context of the device. Exploitation requires user interaction, specifically that the user must initiate the device pairing process. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
