AMD drops after admitting vulnerability to Spectre flaw

Microsoft to block future Windows updates if your antivirus isn't set properly AMD drops after admitting vulnerability to Spectre flaw

Processor vulnerabilities Spectre and Meltdown have been a nightmare for Intel this month. This is by design to protect critical security information like usernames, passwords and encryption keys.

As this process unfolds, I want to be clear about Intel's commitments to our customers. We expect to make updates available for our previous generation products over the coming weeks.

Apple claims that performance of Macs, iPhones and iPads is largely unaffected by the patches, stating "our testing with public benchmarks has shown that the changes in the December 2017 updates resulted in no measurable reduction in the performance of macOS and iOS as measured by the GeekBench 4 benchmark, or in common Web browsing benchmarks".

"Transparent and Timely Communications: As we roll out software and firmware patches, we are learning a great deal". The more worrisome issue is with older PCs from the 2015-era and earlier.

Current information about known patches can be found here. 'Our customers' security is an ongoing priority, not a one-time event. The flaw has left massive numbers of CPUs potentially susceptible to intrusion and data theft, and NVIDIA's patch indicates that certain GPUs may also be vulnerable.

Other security software providers that have also updated their antivirus software include Bitdefender, F-Secure, Kaspersky and Sophos. And yes, these CPU flaws affect phones and tablets too.

Microsoft is distributing patches for the majority of AMD systems now.

The magnitude of the Meltdown/Spectre debacle is yet to be truly understood. However, fix for the second variant of Spectre will bring more significant slowdowns and the users would notice a performance decrease in their systems. This particular bug allows for 'Branch Target Injection' and is applicable to AMD processors. All of the test rigs were equipped with SSDs, although Intel also tested the Skylake-and-Windows-7 combo on a hard-drive-based system.

While Intel has been the overwhelming focus during the fallout surrounding the Meltdown and Spectre processor exploits revealed last week, AMD has managed to, for the most part, fly below the radar. If they don't, their systems will suffer from the system slowdown that comes with the Meltdown patches without improving security. The performance hit was especially felt on computers and servers running on older Intel processors.
