Meltdown and Spectre
Bugs in modern computers leak passwords and sensitive data.
Spectre
Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre
Who reported Spectre?
Spectre was independently discovered and reported by two people:
Jann Horn (Google Project Zero) and
Paul Kocher in collaboration with, in alphabetical order, Daniel Genkin (University of Pennsylvania and University of Maryland), Mike Hamburg (Rambus), Moritz Lipp (Graz University of Technology), and Yuval Yarom (University of Adelaide and Data61)
At the moment, it is unclear whether ARM and AMD processors are also affected by Meltdown.

Meltdown
Meltdown breaks the most fundamental isolation between user applications and the operating system. This attack allows a program to access the memory, and thus also the secrets, of other programs and the operating system.
Who reported Meltdown?
Meltdown was independently discovered and reported by three teams:
Jann Horn (Google Project Zero),
Werner Haas, Thomas Prescher (Cyberus Technology),
Daniel Gruss, Moritz Lipp, Stefan Mangard, Michael Schwarz (Graz University of Technology)
At the moment, it is unclear whether ARM and AMD processors are also affected by Meltdown.
