Summary On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17, the video-core process incorrectly extracts fields from a user-controlled JSON payload, leading to a buffer overflow on the stack.

An attacker can send an arbitrarily long "user" value in order to exploit this vulnerability.
