Students would often come to school with an assortment of file formats from software that was bundled with computers they or their parents had purchased in local stores. Supporting differing file formats was difficult, and by distributing OpenOffice (and later, LibreOffice) to students and teaching them how to save files in a format that they could share with their teachers was a boon.

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
