Bitdefender Researchers Discover New Side-Channel Attack

Mar 10 by Shaun Donaldson
  • This new speculative-execution-based attack exploits flaws in the CPU architecture to potentially leak information from protected memory
  • Dubbed LVI-LFB (Load Value Injection in the Line Fill Buffers), this is a novel attack (CVE-2020-0551)
  • Bitdefender has developed a synthetic Proof of Concept which demonstrates the viability of this new attack
  • Existing mitigations for previous attacks, such-as Meltdown, Spectre, and MDS are not sufficient to completely remove the new vulnerability

A Brief History Leading to LVI-LFB

In 2018, two new types of microarchitectural side-channel attacks were disclosed: Meltdown and Spectre. Meltdown allows an attacker to speculatively access memory that is inaccessible, while Spectre allows an attacker to alter the branch prediction structures in order to gain speculative arbitrary code execution. In 2019, another class of microarchitectural side-channel attacks was disclosed: Microarchitectural Data Sampling, or MDS. It allows an attacker to pick-up in-flight data from various microarchitectural data structures (line fill buffers or LFBs - MFBDS, load ports - MLPDS or store buffers - MSBDS).
