Intel posts details of speculative execution vulnerability

By Nick Flaherty www.flaherty.co.uk

Intel has posted its detailed response to the Meltdown and Spectre vulnerabilities in its processors.

"As detailed by Google Project Zero, a new series of side-channel analysis methods have been discovered that potentially facilitate access to unauthorised information," said the company. "These methods rely on common properties of both high-performance microprocessors modern operating systems and susceptibility is not limited to Intel processors, nor does it imply the processor is working outside its intended functional specification. All of the methods take advantage of speculative execution, a common technique in processors used to achieve high performance. Intel is working closely with our partners, as well as with other silicon vendors whose processors are affected, to design mitigations for these methods."

The issues are detailed in a white paper along with the techniques used to stop the data being accessed.
