New Meltdown, Spectre Vulnerabilities Discovered

A team of researchers revealed this week two new Meltdown attacks and five new Spectre attacks affecting AMD, ARM, and Intel processors.

 

The researchers said that they were able to demonstrate all seven attacks with proof-of-concept code. However, experiments to confirm six other Meltdown-attacks did not succeed.

 

The flaws were discovered during a sound and extensible systematization of transient execution attacks. This is a catch-all term used to refer to attacks on the various internal mechanisms that a CPU uses to process data, such as the speculative execution process, the CPU’s internal caches, and other internal execution stages.
