Security Researchers Publish Ryzen Flaws, Gave AMD 24 hours Prior Notice

Through the advent of Meltdown and Spectre, there is a heightened element of nervousness around potential security flaws in modern high-performance processors, especially those that deal with the core and critical components of company business and international infrastructure. Today, CTS-Labs, a security company based in Israel, has published a whitepaper identifying four classes of potential vulnerabilities of the Ryzen, EPYC, Ryzen Pro, and Ryzen Mobile processor lines. AMD is in the process of responding to the claims, but was only given 24 hours of notice rather than the typical 90 days for standard vulnerability disclosure. No official reason was given for the shortened time.

[...] At this point AMD has not confirmed any of the issues brought forth in the CTS-Labs whitepaper, so we cannot confirm in the findings are accurate. It has been brought to our attention that some press were pre-briefed on the issue, perhaps before AMD was notified, and that the website that CTS-Labs has setup for the issue was registered on February 22nd, several weeks ago. Given the level of graphics on the site, it does look like a planned 'announcement' has been in the works for a little while, seemingly with little regard for AMD's response on the issue. This is compared to Meltdown and Spectre, which was shared among the affected companies several months before a planned public disclosure. CTS-Labs has also hired a PR firm to deal with incoming requests for information, which is also an interesting avenue to the story, as this is normally not the route these security companies take. CTS-Labs is a security focused research firm, but does not disclose its customers or research leading to this disclosure. CTS-Labs was started in 2017, and this is their first public report.

CTS-Labs' claims revolve around AMD's Secure Processor and Promontory Chipset, and fall into four main categories, which CTS-Labs has named for maximum effect. Each category has sub-sections within.

Severe Security Advisory on AMD Processors from CTS.

    Axl was always a little bitch. But back then, he was entertaining, talented, and also managed to hold his band together so they could actually produce a good amount of material and get it published, and go on tour with it. Somewhere in the mid-90s it all fell apart and he couldn't keep things together for some reason.

    I definitely miss those days, at least for the music. Today's music is crap, and it's not because I'm older. Music went down the tubes in the US starting with grunge and "alternative", and then really went to hell after ~2000, which, I hate to say it, seems to coincide with Napster and file-trading (but also coincides with widespread availability of the internet).

    IMO, the only ones who did grunge properly were Nirvana. Nevermind belongs in any fan of American music's collection. It did come out at a time that was more or less the beginning of the end for good rock music in the US though.

    It's not even just rock either. Country music kind of went to shit around the same time. Most of what you hear nowadays on country stations could be more accurately described as twang-pop and is preformed by manscaped little bitches whose boots have never seen cow shit and soulless, carbon copy blonde chicks who grew up in suburbia.

    Looking back, you know what I think caused it all? Johnny Cash died.

      I was never much of a fan of grunge, but I did like Pearl Jam's first album, Ten, and have it in my collection. But I didn't like anything they made afterwards.

      I've heard it called "redneck rock". Though I haven't listened to much country, I agree that it definitely seems that it's lost whatever authenticity that it once had.

      No, you could just as easily blame it on anything else that coincided, such as the invention of the WWW, the move away from boxiness in cars (remember how boxy 80s cars were?), the first Gulf War, the breakup of the Soviet Union, etc.

      It'd be interesting to arrange a panel of long-time music industry insiders and see what they come up with after asking them to debate it. I think it's probably a convergence of many different factors; the internet might be part of it, but I saw music going downhill in the early 90s, before Napster was invented and before MP3 became a thing, though the internet seemed to make it worse. Also, it seems like things are really different overseas; back in the 80s I think western Europeans and Americans shared much of the same tastes in music (look how many pop acts crossed the ocean--ABBA was from Sweden for instance, and lots of rock bands came from England such as Def Leppard and of course The Beatles), whereas after this shift it seemed that Americans went their own way with music, and now there's little or nothing crossing the Atlantic like before. I've been a big metal fan, but in the 90s Americans completely lost all interest in metal, whereas in Europe and even Japan it stayed popular for a long time, and is still much more popular there than here.

        sounds about right for you.

        Well it was mostly said in jest but there's a case to be made that Cash had a bigger influence on American music culture than most anyone else due to his inter-demographic popularity, his longevity, and a style that fit in as well with Elvis as it did with Willie or NIN.

          Johnny Cash's version of 'Hurt' is one of the most moving and awesome songs ever.

        It all seemed to fall to shit with the advent of "formula rock", where startup bands copied riffs, themes, and progressions from the "greats".

      Dilly Dally [youtube.com] might be up your alley. Honestly I only found about them now looking up "modern grunge 2017" and ending up in this post [reddit.com] which is full of bands you might like...

      Personally, Nirvana was something of a first love for me so I can't really say I'm not fond of popular music at all... But somewhere along The Black Dahlia Murder's What A Horrible Night To Have A Curse, Russ Liquid's Feral Cat, Animals As Leaders's An Infinite Regression and Meshuggah's The Demon's Name Is Surveillance, I've realized I'll never find music I like unless I'll actively look it up. Take it however you like it.

      Btw, Tool finally booked recording time: https://consequenceofsound.net/2018/03/tools-new-album-is-about-to-begin-in-earnest/ [consequenceofsound.net] Came up reading your post and realizing the only country I ever liked was a certain Pusifer track [youtube.com] :D

    There might be something to that correlation (the rise of shitty music vs the rise of the internets).

    It's not that there's less good music today. People are making *lots* of good music everywhere. it just stays in their respective niche markets and the 'pop' market which is played on radio/tv and linked to from the main interwebs pages is getting more bland by the year.

    I think it has something to do with the big record labels playing it safe all the time. Also, the 'record deal' is not really the holy grail in musicianship anymore. Selling CD's has become a form of promotion, and not your main source of income. Playing live is where you have to make your money now (just like pre-1900 actually, but harder because people don't *need* to book a band to have music). Most band I like self-publish their music these days. But the self-published stuff won't be heard in the 'mainstream' media of course.

      I think there may be something to that, and I think there's a big parallel in the movie industry. They don't make risky movies much any more, so we don't see big blockbusters like "Alien" (which at the time was an all-new thing) or Blade Runner, but instead we do see sequels to these decades-old movies. In their mind, it's better to make a smaller profit on a big-budget sequel/franchise movie (like yet another Marvel comic movie) than to potentially make a giant profit on something all-new, but risk it being a flop.

        I will build on it and say that it is because public is media saturated and that makes it difficult for it to try something new unless it has been heavily marketed. When you have to have multi-million dollar budget just for marketing of an already well established brand like marvel, imagine the minimum risk involved in a new concept.

        TL;DR After watching tub-girl and goatse one will prefer watching a safe formulaic movie.
