On Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17 the video-core process insecurely extracts the fields from the \shard\ table of its SQLite database leading to a buffer overflow on the stack. The strcpy call overflows the destination buffer which has a size of 128 bytes. An attacker can send an arbitrarily long \secretKey\ value in order to exploit this vulnerability.
