Subtitle Hack Leaves 200 Million Vulnerable to Remote Code Execution

 

Check Point researchers revealed a new attack vector which threatens millions of users worldwide – attack by subtitles. By crafting malicious subtitle files, which are then downloaded by a victim’s media player, attackers can take complete control over any type of device via vulnerabilities found in many popular streaming platforms, including VLC, Kodi (XBMC), Popcorn-Time and strem.io.

It’s common to see subtitle files (usually a .srt or .sub) included in torrents and other less-than-legal movie downloads, so people tend to simply ignore them. You can load this file into most video players to display subtitles in the chosen language synced to the video. Check Point says that there are roughly 200 million installations of video players vulnerable to this exploit including VLC, Kodi, Popcorn-Time, and Stream.io.
