FreeBSD 12 & DragonFlyBSD 5.6 Running Well On The AMD Ryzen 7 3700X + MSI X570 GODLIKE

For those wondering how well FreeBSD and DragonFlyBSD are handling AMD's new Ryzen 3000 series desktop processors, here are some benchmarks on a Ryzen 7 3700X with MSI MEG X570 GODLIKE where both of these popular BSD operating systems were working out-of-the-box. For some fun mid-week benchmarking, here are those results of FreeBSD 12.0 and DragonFlyBSD 5.6.2 up against openSUSE Tumbleweed and Ubuntu 19.04. Back in July I looked at FreeBSD 12 on the Ryzen 9 3900X but at that time at least DragonFlyBSD had troubles booting on that system. When trying out the Ryzen 7 3700X + MSI GODLIKE X570 motherboard on the latest BIOS, everything "just worked" without any compatibility issues for either of these BSDs. Read more

How to break out of a hypervisor: Abuse Qemu-KVM on-Linux pre-5.3 – or VMware with an AMD driver

A pair of newly disclosed security flaws could allow malicious virtual machine guests to break out of their hypervisor's walled gardens and execute malicious code on the host box. Both CVE-2019-14835 and CVE-2019-5049 are not particularly easy to exploit as they require specific types of hardware or events to occur. However, if successful, either could allow a miscreant to run malware on the host from a VM instance. CVE-2019-14835 was discovered and reported by Peter Pi, a member of the Tencent Blade Team. It is found in the Linux kernel versions 2.6.34 up to version 5.3, where it is patched. Read more
