​The return of Spectre


Video: Intel's patches for Spectre variant 4 will slow your CPU

The return of Spectre sounds like the next James Bond movie, but it's really the discovery of two new Spectre-style CPU attacks.

Vladimir Kiriansky, a Ph.D. candidate at MIT, and independent researcher Carl Waldspurger found the latest two security holes. They have since published a MIT paper, Speculative Buffer Overflows: Attacks and Defenses, which go over these bugs in great detail. Together, these problems are called "speculative execution side-channel attacks."

These discoveries can't really come as a surprise. Spectre and Meltdown are a new class of security holes. They're deeply embedded in the fundamental design of recent generations of processors. To go faster, modern chips use a combination of pipelining, out-of-order execution, branch prediction, and speculative execution to run the next branch of a program before it's called on. This way, no time is wasted if your application goes down that path....(continued)
