Linux and CPU Security

  • 22 essential security commands for Linux
    There are many aspects to security on Linux systems – from setting up accounts to ensuring that legitimate users have no more privilege than they need to do their jobs. This is look at some of the most essential security commands for day-to-day work on Linux systems.
  • CVE-2018-3639: Spectre Variant 4 Vulnerability Affects the Linux Kernel
    A Spectre variant 4 vulnerability has been identified in the Linux kernel and represents a very dangerous threat to all affected machines. All system administrators are urged to apply the latest updates as soon as possible to mitigate any possible impact.
  • Spectre Number 4, STEP RIGHT UP!
    In the continuing saga of Meltdown and Spectre (tl;dr: G4/7400, G3 and likely earlier 60x PowerPCs don't seem vulnerable at all; G4/7450 and G5 are so far affected by Spectre while Meltdown has not been confirmed, but IBM documentation implies "big" POWER4 and up are vulnerable to both) is now Spectre variant 4. In this variant, the fundamental issue of getting the CPU to speculatively execute code it mistakenly predicts will be executed and observing the effects on cache timing is still present, but here the trick has to do with executing a downstream memory load operation speculatively before other store operations that the load does not depend on. If the CPU is convinced to speculatively execute down this victim path incorrectly, it will revert the stores and the register load when the mispredict is discovered, but the loaded address will remain in the L1 cache and be observable through means similar to those in other Spectre-type attacks.
