Media playback system

Abstract

Media playback functionality is essential to any Smart TV (STV). Common features such as the built-in media player, video-on-demand apps, or the web browser build upon this functionality, which is often implemented in the form of a central media playback system. The processing of media files is a complex task, however, and without appropriate protection measures, vulnerabilities in this component can lead to the complete compromise of the STV. This chapter presents two vulnerabilities and corresponding PoC exploits that are able to fully compromise all previous STV generations from a major vendor.
