Microsoft fixes vulnerabilities in Office, Adobe, Windows”

It also has been reported that some of the recently developed patches can downgrade processor performance anywhere from five-to-35%.

"Microsoft started Patch Tuesday a little early this month by releasing the operating system updates last week", Ivanti's Chris Goetti said.

However, anyone running the operating system on older silicon, such as 2015-era PCs with Haswell or older, can expect to see more "significant slowdowns", which means they will likely notice a degradation e in system performance.

An AMD spokesperson told CRN at the time that the company does not need to release any firmware or OS updates to address the Spectre and Meltdown issues. "We will then focus on issuing updates for older products as prioritised by our customers", Krzanich noted. What we did is we released driver updates to patch the CPU security vulnerability. For example, all fonts in Windows 7 and 8 are rendered on the kernel, the software that controls the processor. This is by design to protect critical security information like usernames, passwords and encryption keys.

The flaws affect virtually all computing devices running on chips manufactured by Intel, AMD and ARM, although the worst - called Meltdown - largely just affects Intel.

Variant 1 (CVE-2017-5753): Mitigations are provided with the security update included in this bulletin.

Three firmware issues have been flagged by the company in updates released over the past week, according to a confidential document reviewed by The Wall Street Journal. The situation is still developing, but Spanning is proactively working to ensure customer data is protected. Intel's corporate customers may have to choose between installing Microsoft's fixes or taking the performance hit that installing those fixes will mean.

In addition to other promises, Intel is committing to publically identify future vulnerabilities and "share hardware innovations that will accelerate industry-level progress in dealing with side-channel attacks".

AMD shares dropped as much as 4 percent to $11.65 in after-hours trading after the company's announcement Thursday.

The slowdown particularly affects Intel chips vulnerable to Meltdown.

This stood in contrast to AMD's original response on January 3 to the Spectre and Meltdown vulnerabilities when it blogged that there was currently "near-zero risk" to its processors from vulnerabilities associated with the Spectre and Meltdown issues.
