Check Point researchers revealed a new attack vector threatening millions of users of popular media players, including VLC, Kodi (XBMC), Popcorn Time and Stremio. By crafting malicious subtitle files for films and TV programmes, which are then downloaded by viewers, attackers can potentially take complete control of any device running the vulnerable platforms.

"The supply chain for subtitles is complex, with over 25 different subtitle formats in use, all with unique features and capabilities. This fragmented ecosystem, along with limited security, means there are multiple vulnerabilities that could be exploited, making it a hugely attractive target for attackers," said Omri Herscovici, vulnerability research team leader at Check Point.

The subtitles for films or TV shows are created by a wide range of subtitle writers, and uploaded to shared online repositories, such as OpenSubtitles.org, where they are indexed and ranked. Researchers also demonstrated that by manipulating the repositories' ranking algorithm, malicious subtitles can be automatically downloaded by the media player, allowing a hacker to take complete control over the entire subtitle supply chain without user interaction.

    However, the problem is that computers are made by humans, and the systems are so complex, that really they only function at all due to more work than any one person can handle. The result is that despite there being the initial sense that one can just take a decently functioning system and customize it for oneself over the course of the rest of one's own miserable life, the truth of the matter is that you actually always depend on a "community" that suffers from politics, shifting goals, and just general human mediocrity.

    Even if you are successful at making your system work well for you, the hardware will eventually fail, and then you'll find there's nothing new out there with which to replace your broken system, except for systems that come broken by design, purposefully sealed off as magical and unhackable black boxes, choked under cryptographic DRM, and backdoored in the most intimate levels by the powers-that-be.

    Enjoy.
