Canonical Releases Important Linux Kernel Patch for Ubuntu 16.04 LTS, Update Now

Canonical released a new Linux kernel security update for users of the Ubuntu 16.04 LTS (Xenial Xerus) operating system series to address several recently discovered vulnerabilities.

The new Linux kernel security update is here to address five security issues discovered by various security researchers in the Linux 4.4 kernel used in the Ubuntu 16.04 LTS (Xenial Xerus) operating system series and official derivatives that aren’t using the Linux 4.15 HWE (Hardware Enablement) kernel from Ubuntu 18.04 LTS (Bionic Beaver).

These include a flaw (CVE-2017-18241) in Linux kernel’s F2FS file system implementation, which incorrectly handled the noflush_merge mount option, and multiple integer overflows (CVE-2018-7740) in the hugetlbfs implementation. Both issues could allow local attackers to crash the vulnerable system… (read more)

Linus Torvalds Kicks Off Development of Linux 5.1 Kernel, First RC Is Out Now

Linus Torvalds kicked off today the development cycle of the forthcoming Linux 5.1 kernel series with the release of the first RC (Release Candidate) milestone for public testing.

Two weeks have passed since the release of the major Linux 5.0 kernel series, so now the merge window is closed for the next release, Linux kernel 5.1, and the new development cycle is open. Everything is in normal parameters for the Linux 5.1 kernel, which now has a first Release Candidate milestone ready for public testing.

“It’s Sunday, and two weeks have passed, and everything is normal. You all know the drill by now – the merge window is closed, and things are supposed to calm down,” said Linus Torvalds. “The merge window felt fairly normal to me. And looking at the stats, nothing really odd stands out either. It’s a regular sized … (read more)

Solus 4 “Fortitude” Officially Released, It’s Now Available for Download

The Solus Project announced today the general and immediate availability for download of the long-anticipated Solus 4 Linux-based operating system.

More than a year in the making, the Solus 4 release is finally here as an up-to-date live and installable medium that users can use to deploy the independently developed GNU/Linux distribution on their computer without having to download hundreds of updates from the software repositories.

“We are proud to announce the immediate availability of Solus 4 Fortitude, a new major release of the Solus operating system. This release delivers a brand new Budgie experience, updated sets of default applications and theming, and hardware enablement,” said Joshua Strobl in today’s announcement.

Do You Have A Security Strategy To Protect Your Backups?

It’s not enough to back up data. That doesn’t necessarily guarantee total protection. Even if backups are hidden away in the network, you should never eliminate the thought of losing data.

The question you should ask yourself is this. Is the network safe enough to protect backups? If you think it is, then good for you. Still, that shouldn’t stop you from creating a security strategy to protect backups.

One sure way to avoid total data loss is to protect the network itself. With advanced persistent threats continuously progressing, no network is safe. That is scary.

Ransomware is one of the advanced persistent threats to networks these days. It stays quiet and undetected within the network. Eventually it steals data so that the ransom writer can sell it back to the owner. It’s simple extortion that could put any company out of business in no time.

There has been a tactical pivot in ransomware. It seems that ransomware writers have realized that large organizations have lots of money, and some do not have the best protection against infections. Newer ransomware is behaving as an advanced persistent threat, a piece of malware that tries to stay undetected in your network for some time to do the maximum amount of damage.

The APT will usually spread through your network, infecting as many computers as possible. Often, the malware will try to connect to a command-and-control server over the internet to report the progress of the infection and await the command to attack.

(Via: https://searchdatabackup.techtarget.com/tip/How-to-protect-backups-from-ransomware-infiltration)

Unfortunately, these days the use of command and control or C &C server is evolving to do more damage to the network. It stays silent and undetected in the background so that it could have access to the network for a very long time, eventually endangering computers and backups.

A ransomware APT attack may start by stealthily spreading itself through your network and infecting all of your computers. It will then seek out file-based backups and valuable but older files to encrypt. The aim is to get as much of your infrastructure infected and encrypted — over a period of weeks or months — before you are

Canonical Releases Minor Linux Kernel Security Update for Ubuntu 14.04 LTS

Canonical released a new Linux kernel update for the long-term supported Ubuntu 14.04 LTS (Trusty Tahr) operating system series to address a recently discovered security vulnerability.

A security issue affects the Linux 3.13 kernel of the Ubuntu 14.04 LTS (Trusty Tahr) operating system series and its derivatives, including Kubuntu, Xubuntu, Lubuntu, Ubuntu Kylin, Ubuntu Studio, Mythbuntu, and others, allowing attackers to run programs as an administrator.

The vulnerability is a race condition (CVE-2019-6133) discovered by Jann Horn of Google Project Zero in Linux kernel’s fork() system call, which could allow a local attacker to gain access to services storing cache authorizations and run programs with administrative privileges.

“The system could be made to run programs as an administrator. Jann Horn discovered a race condition in the fork() system call in the Linux kernel. A local attac… (read more)
