Processor Vulnerabilities

Notice from Norton: Meltdown and Spectre: Chip Vulnerabilities Could Facilitate Memory Leaks

Windows 7 does not have a patch as far as I know. The patches will slow the computing down.

It is the greatest disaster of computer technology ever. Read here:

Re: Processor Vulnerabilities

That it was known so long, while the Intel president, traded out of his stock options and had months to change the "rules" is totally criminal. Intel abandoned serving their customer base, an act Andy would not have tolerated.

Thanks Carcode. I will read it. Looks like we have to go all the way back to Atom processors to be safe.

Re: Processor Vulnerabilities

It makes good headlines, and it’s a very serious design error, but it’s VERY difficult to exploit in a useful way. It would require sophisticated skills and computing power to reassemble the memory fragments into usable information. Criminal types wouldn’t see a good ROI so they’ll stick with ransomware, credit fraud and phishing. This is fodder for nation states and even then it would only be used on focused high value targets.

Bottom line, you and me should be more concerned about other stuff. Do your software and firmware updates and move on.

PS you can’t stick with old unsupported software forever.

Microsoft issued updates for Windows 10, Windows 8 and Windows 7 as well as for its Azure cloud operating system

As of Wednesday evening, Apple had yet to comment on how its products are impacted.

INtel has it's head in the sand!

The costs: Despite how widespread the problem is, Intel says it doesn't expect any significant financial impact. Other potential costs will be born by software makers creating patches and those that may see a performance impact from the software patches needed to close the security hole. It's also possible class-action lawyers may see this as a prime opportunity to litigate.

Apple now say all Mac and iOS devices are affected too.

Re: Processor Vulnerabilities

It's overblown. Google: "Intel overblown" and "Intel overreaction".

Re: Processor Vulnerabilities

I'm sure it is. My (limited) understanding is that to gather any data at all the undetected malware has to be virtually inside the processor. It's just not going to happen for the vast majority of users.

Re: Processor Vulnerabilities

And now everybody grab your tea, sit back, take a deep breath, update your browser for the, hard to exploit, stuff through Javascript when available during the next few days, and let the big cloud running guys do their job they started to do before you even heard the words Meltdown and Spectre for the first time. These are "disaster" for the cloud industry, of limited importance for the end user, certainly not more important than the other dozen we have seen in the last year, really.

Eben Upton (Raspberry PI):

"Meltdown and Spectre are examples of what happens when we reason about security in the context of that abstraction, and then encounter minor discrepancies between the abstraction and reality. The lack of speculation in the ARM1176, Cortex-A7, and Cortex-A53 cores used in Raspberry Pi render us immune to attacks of the sort."

Re: Processor Vulnerabilities

If you could sneak a program that exploits this vulnerability onto an OpenCpn user's machine you could capture the assembly code, reverse compile it and then publish the source code to O.

Re: Processor Vulnerabilities

Read this posting from Linus Torvalds to understand what **** is going on:
Linux-Kernel Archive: Re: [RFC 09/10] x86/enter: Create macros to restrict/unrestrict Indirect Branch Speculation

It seems he has lost his patience.
