CVE-2018-3917: Buffer Overflow

First published: Thu Aug 23 2018(Updated: )

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. An attacker can send an HTTP request to trigger this vulnerability. The strcpy call overflows the destination buffer, which has a size of 16 bytes. An attacker can send an arbitrarily long "region" value in order to exploit this vulnerability.
