AMD allegedly has its own Spectre-like security flaws


That's the title of an article published by CNET:
https://www.cnet.com/news/amd-has-a-...aw-of-its-own/

Happy reading.

This smells like a hit-job by Intel. The vulnerabilities not only aren't speculative execution information leak vulnerabilities that would be similar to Spectre and Meltdown, but they also don't seem like they would be usable in the real world.

The lack of any kind of emergency response to fix this will be the proof.

yes, the 24-hour lead-time is Very Nasty.

Sounds kinda like the Windows Crypto-Locker Scheme ( pay us now or pay us later ).

There's some discussion on slashdot: https://it.slashdot.org/story/18/03/...indings-public

One of the posts in the slashdot discussion points at the Blackmailer's site: https://amdflaws.com/

From what I can tell, they're a bunch of *'s ( apologies for plagiarizing Kurt Vonnegut )

Yeah, yeah...

BUT, like I said somewhere, the Age of Hardware Vulnerabilities has just begun with Spectre/Meltdown public release and the Heroic Age of Manually Building Packages ended in that day...

Dear Patrick, with all respect I strongly suggest you to arrive to "slackware.SlackBuild" and to ensure you can clean rebuild the entire distribution just hitting it. Just in case, maybe you will need it in a weekly base...

Such a script would certainly have to be rewritten for the new magic build order before every use. Just look at what nobodino is doing.

From the link in post #1

The majority of these reported vulnerabilities would require administrative access to work, meaning an attacker would first need to have control of your machine through some type of malware.
The article gives the impression that these exploits are working against the Windows 10 operating system.

Let's be honest. Speculative and out-of-order execution has been the holy grail of CPU design for a number of years, and they are the major reason for the dramatic increase in CPU power seen in this millenium. We can expect more leeching of side-band information using these mechanisms, in CPUs by all vendors.

I am not so worried that these mechanisms can be abused by persons with local access to a machine - which is bad enough in the current climate of state-owned espionage against their own citizens.

To me, the real scandal is a different one: namely that we allow web browsers to execute Turing-complete software in realtime, allowing remote attackers to exploit this type of security flaw, and others.

Given all I've read, heard and seen about it I'd guess
this is some kind of stock-price opportunism.
Sad thing is that it works.

Still have to note that "require administrative access to the system", it's only on a small set of their processors, and it's nothing like Spectre/Meltdown.

The person(s) who "disclosed" the information was very much an amateur and I wouldn't give them the time of day for how they handled the situation.

So if I understand well and believe AMD's response I involuntary did spread FUD, as if someone gets root access on a computer all doors are of course open to do nasty things any way.

I am thus tagging this thread as [SOLVED], thanks abga for the link and Skaendo for the comment.

It's not that AMD doesn't have problems, it's just that it has been blown *WAY* out of proportion by some person(s) looking for fame or money.

You're already famous in my book, but how much money did you make on this Thread ?
