Canonical announced on Tuesday that Ubuntu Pro is available in a subscription-included model on Amazon Web Services. With Ubuntu Pro on AWS, users can launch Ubuntu Pro on-demand instances and purchase Ubuntu Pro compute savings plans directly from the Amazon Elastic Compute Cloud console.
On the third day of the Pwn2Own hacking contest, security researchers were awarded $185,000 after demonstrating 5 zero-day exploits targeting Windows 11, Ubuntu Desktop, and the VMware Workstation virtualization software. The highlight of the day was the Ubuntu Desktop operating system getting hacked three times by three different teams, although one of them was a collision with the exploit being previously known.
On the first day of Pwn2Own Vancouver 2023, security researchers successfully demoed Tesla Model 3, Windows 11, and macOS zero-day exploits and exploit chains to win $375,000 and a Tesla Model 3. The STAR Labs team demoed a zero-day exploit chain targeting Microsoft's SharePoint team collaboration platform that brought them a $100,000 reward and successfully hacked Ubuntu Desktop with a previously known exploit for $15,000.
Microsoft Azure customers' virtual machines running Ubuntu 18.04 have been taken offline by an ongoing outage caused by a faulty systemd update. Microsoft says in an incident report published on the Azure status page that these DNS issues only affect VMs running Ubuntu 18.04.
You don't want that, but how do you prevent such a reality? One way is to enable two-factor authentication on the server. How do you set up SSH 2FA on your Ubuntu Server? Let me show you.
Canonical has announced the general availability of version 22.04 of the Ubuntu Linux distribution, codenamed 'Jammy Jellyfish', which brings better hardware support and an improved security baseline. Ubuntu is the world's most popular Linux distribution for consumers.
Ubuntu has issued a batch of updates that cover the default as well as the AWS and KVM flavours for the current short-term release 21.10, both the original 5.04 and OEM 5.14 builds for the current 20.04 LTS release, as well as 18.04, and, surprisingly, even 16.04 and 14.04. While kernel releases trickle out all the time, the last two members of that list - 2016's Xenial Xerus and 2014's Trusty Tahr - emphasise that even very old releases in Extended Security Maintenance or ESM sometimes need a bit of TLC. It also might surprise some that multiple different Linux kernels are available for a single product release.
The CVE-2022-0185 vulnerability in Ubuntu is severe enough that Red Hat is also advising immediate patching. It affects RHEL as well as Ubuntu 20.04, 21.04 and 21.10 - and presumably other distros, too.
If you'd like a powerful firewall for your Ubuntu Server, but one that offers a fairly straightforward configuration, Jack Wallen thinks CSF might be the right tool for the job. Although Uncomplicated Firewall is an outstanding security service on Ubuntu Server, there might be times when you need more.
