Okay, so Specter – and its associated vulnerability meltdown – were identified and some aspects were treated by CPU microcode and OS patches. Unfortunately, in the case of Specter, these solutions resulted in a loss of system performance. The good news is for Windows 10 users, an upcoming update will reduce the impact on the “noise level” (a few percentage points).
Lessons from Meltdown and Specter Debacle
The information on the vulnerabilities and melting years vulnerabilities on January 2, 201
8 was in many ways unmatched.
A recent tweet from Mehmet Iyigun Partner Development Manager on the Windows kernel team, provides a technical overview of the update:
In essence, Microsoft assumes a new approach called “retpolin” originally designed and implemented by Google. The search giant wrote an explanation of how it works earlier this year:
In response to the vulnerabilities discovered, we developed a new modification method called Retpoline – a binary modification method that protects against attack on branch injection.
We shared Retpoline with our industry partners and distributed it on Google’s system, where we observed negligible impact on performance.
As the writing, the fix has not yet been released to the public, but should find its way into Microsoft’s next run of updates.
Intel Chips are designed to mitigate spectrum and melting Vulnerabilities will happen later this year, says CEO
Intel has announced that its next generation Xeon and Core processors are intended to protect users against the almost universal Specter and Meltdown vulnerabilities that were first revealed in January.
