CVE-2018-3905: Buffer Overflow

First published: Thu Aug 23 2018(Updated: )

An exploitable buffer overflow vulnerability exists in the camera "create" feature of video-core's HTTP server of Samsung SmartThings Hub STH-ETH-250 devices with firmware version 0.20.17. The video-core process incorrectly extracts the "state" field from a user-controlled JSON payload, leading to a buffer overflow on the stack. An attacker can send an HTTP request to trigger this vulnerability.
