  • same amount of effort

    Physical effort, yes. Cognitive effort, no.

    • Intros on a serial show are expected, and in some cases change subtly from one episode to another to provide additional entertainment value (eg the Simpsons intro). In other cases a change of intro sets the setting for the episode (eg Star Trek: Enterprise’s Storm Front episodes).
    • YouTube ads are not related to the show, provide no contextual value, and in the case of interstitial ads are not even at a predictable time. They also tend to be inanely repetitive, showing the same ad over and over in consecutive videos. Contrast those to eg halftime ads at the Superbowl broadcasts, which have predictable timing, variety, and have a history of being (or trying to be) entertaining.

  • CUPS is installed on the majority of desktop systems. One of the listed CVEs indicates that port 631 is by default open to the local network, so if you connect to any shared network (public WiFi, work/school network, even your home network if another compromised device gets connected to it) you’re exposed. Or a browser flaw or other vulnerability could be exploited to forward a packet to that port.

    In other words: While access to port 631 is required first, the severity of the vulnerability lies in how damn easy it is to take over a system after that. And the system can be re-compromised any time you print something, making this a persistent vector.








  • The article’s author mentioned that the problem is not limited to Samsung TVs - someone reported the issue on their phone.

    The article does not mention a root cause, but I have a theory that it’s likely a malformed subtitle track. I tend to watch with subtitles on so I run into related issues every once in a while. Most of the time it’s one of two things:

    • The subtitles are misaligned (eg wrong offset, addressed by adding a positive or negative delay to the track)
    • Bad formatting on the timing information.

    The latter can have multiple effects depending on what format the subs are in, but most of the time it’s a missing end time, meaning that the subtitle stays on. However, some formats also have cues as to who the speaker is, and that comes with a start and end tag like in HTML. I suspect that in this case the end tag is either missing or misaligned in the syntax tree, causing this one line of dialogue to be displayed over and over when the player reaches other lines matching the cue for it, but that don’t get shown because the user has turned subtitles off.

    As to why this is bleeding into other shows: I suspect it’s an issue with how the software clients are caching the subtitle files. This would also explain why going back into the episode that caused this fixes things, because it would reset the cached file. Which in turn brings me back to pointing the finger at Amazon, not Samsung, because Samsung would just be loading Amazon’s software client to play the video and subtitles.
