Security issue Spectre/Meltdown: exploiting the CPU

 Security issue Spectre/Meltdown: exploiting the CPU

 

 

You might have noticed a recent hardware security bug that affects
basically all modern processors. As is becoming a "standard", the issue
got its own name. Two names, actually: Spectre and Meltdown. The
discovery is kind of a small revolution with a potential to shake the
IT industry, since this is a completely new class of security problems.

Unfortunately, media often offer distorted information and forums are
full of ungrounded assumptions and misleading information lacking
deeper understanding of the problem.

The presentation will explain in detail what is the core of these issues,
what are the options of fixing them and how will those solutions impact
performance. In the first part, we will talk about how modern processors
operate. In the second part, we will introduce the three discovered
vulnerabilities (Spectre 1, Spectre 2 and Meltdown) along with methods
of protecting against them on a software level. If there's enough
interest, the presentation may be followed by a discussion.

Attendees are expected to understand at least the basics of CPU
functionality (in particular, what instructions and registers are) and
to have an idea how caches work.

Expected length: 2 hours

Presenter: Jiří Benc, Linux Kernel Developer at Red Hat
