    Y’all really need to read past the headline:

    the bug that Paul found seemingly wouldn’t be triggered anyway, as the relevant section of the code wasn’t being called to begin with

      Okay, yes, but that’s because they had messed up their application enough that the updater itself couldn’t be updated, which they presumably discovered in the process of trying to remedy his bug. That is, the flaw he found couldn’t actually be exploited only because of a deeper flaw he hadn’t found. (Shades of the Sirius Cybernetics Corporation there, whose deep fundamental design flaws were almost totally hidden by their superficial design flaws.) He still led them to a critical vulnerability that took them months to fix.

      I guess it’s one of those “justifiable but unwise” sort of things. If your company is doing a bug bounty program to stay on top of security vulnerabilities, what you don’t want is to create the perception that the work of devs who look for these vulnerabilities isn’t appreciated, for example, by skimping on bounties over technicalities.

      Paying the 10k doesn’t ruin the company and allows them to fix a section of code that may become a vulnerability in the future. Not paying the 10k saves them 10k at the price of the devs’ trust that keeps this program effective. From a financial point of view, this is some very poor decision making.

        Sure however it’s still worth calling out click bait headlines and reactionary posters are all being bad actors here in the misinformation spread.

        Probably more important as then developers don’t back out over being emotionally manipulated by fake bullshit.

    Researcher commenting on the patch:

    he remarks that the software only checks the validity of the downloaded file using the ancient CRC32 hash that isn’t considered cryptographically secure anymore

    I have to respect the researcher for his incredibly charitable wording here. CRC32 is not even remotely crypto. That’s never been its purpose, and using it for digital signing is patently insane!

    I fear I would have had a much shorter temper after what he’s been through, and yet here he is keeping his cool and his criticism constructive. Good on him.

        My version of questioning this is if the same source is providing both the file and the hash, does it matter how hard it is to fake the hash? It could just generate a new hash for the fake file, couldn’t it?

        I suppose if the only way to obtain the patch were through an automated download from the AMD website, the authentication through the site certificate would be better than nothing. But this is a security patch, and I think the researcher is right in pointing out that the bar needs to be higher?

    Holy crap. I’d say not to buy AMD if you value your security (i have an AMD CPU and the Deck too). You already know the next vulnerability they’re going to be the last ones to find out. In the news, probably.

      Ok, so the alternative is buying Intel/Nvidia. Surely they’ve never done anything problematic, so this is a good plan.

      Under Linux, AMD GPU is the only sane solution tho, due to open source drivers. And Intel CPUs have history of cookin hard.

        It’s not. RISC-V and ARM exist. You can buy laptops based on either of these architectures for a very reasonable price, compared to Intel and AMD’s x86 offerings.

        Of course, that means no AAA gaming, for the most part at least. But then again, who even plays AAA games these days?

          Gaming industry is way bigger than movie industry. Almost everyone plays games.

          Steam alone has like 40 million concurrent players right now.

          Consumer ARM hardware mostly needs customized images for each board. Plus, depending on your CPU manufacturer you’ll be stuck on an ancient kernel version to get full functionality.

      The Steam Deck does run Linux right? Generally that means the used drivers are not written by AMD and also do not have an auto-updater from AMD. The deck is supposed to update through it’s OS’es package manager and supposedly has the Mesa and Linux Foundation drivers in use.

        It was physics and battery sizes to blame for why we have drifted from the 5 GHz x86 CPU to the 32 core x86 CPU. I never thought the rush to ARM/RISC-V would be because Intel and AMD are run by morons.

      I don’t think a statement is really needed here, this wasn’t a vulnerability, the code was never called. Even if the code were called, the $10,000 bounty is for a different type of bug entirely too

        so stacking vulnerabilities is a thing

        if the code exists it can be called

        this is a valid bug and it’s silly to rule lawyer something like this

        so good job amd, you are ‘actually’ right,

        this totally won’t cost you in the long run at all

        god damn do lawyers and business majors need to stop making tech decisions
