Spectre and Meltdown Exploits

Spectre and Meltdown Exploits

As a result, Microsoft is temporarily halting Windows OS updates to devices with AMD processors affected by this apparent bug. The documentation provided to Microsoft by AMD was apparently inaccurate, which means the patch that Microsoft developed wasn't compatible.

Microsoft said on Tuesday it had suspended patches to guard against Meltdown and Spectre security threats for computers running AMD chipsets after complaints by AMD customers that the software updates froze their machines.

That's the problem facing an unknown number of PC owners using AMD processors. SharedArrayBuffer may return after the company is confident that it can't be used to stage an attack, according to Microsoft Principal Lead Program Manager John Hazen.

Meltdown and Spectre are two memory corruption flaws which could allow hackers bypass operating systems and other security software to steal passwords or encryption keys, on most types of computers, phones and cloud-based servers. The chipmaker didn't immediately respond to a request for comment. The update was delivered through Windows Update to a "quite pre-historic" computer, specifically running on the AMD Athlon X2 6000+, which was released a decade ago.

For the full details on the block put on the update, check out this Microsoft support post. Intel has been working with PC makers to ready firmware updates, but it's fair to say most machines do not have these installed just yet. Hence until the security update gets fixed for Windows PCs with affected AMD chips, they can not be updated to receive the latest protections. We do recommend the AMD owners to not install any updates until the issue is resolved.

As if the Meltdown and Spectre processor security bugs that have been dominating headlines across the internet for the past week weren't scary enough on their own, even the patches for those bugs are causing problems now. But Google publicly confirmed the flaws on Wednesday after outside researchers began independently unearthing the flaws.

Microsoft has released a patch that will be delivered in your normal update cycle for your laptop.

MICROSOFT HAS POINTED the finger of blame in the direction of AMD after update created to protect against the recent Meltdown and Spectre vulnerabilities started bricking machines using the company's processors.

Any organizations preparing to issue the January cumulative patch from Microsoft may prefer to wait until they get one that doesn't leave some AMD systems unbootable.
