An Ubuntu Linux kernel security update fixes 12 security vulnerabilities affecting the Linux 5.4 LTS kernel in Ubuntu 20.04 LTS and Ubuntu 18.04 LTS systems, as well as the Linux 5.11 kernel in Ubuntu 21.04 systems on all supported architectures and platforms.
Apache OpenOffice (AOO) is currently vulnerable to a remote code execution vulnerability (CVE-2021-33035) recently discovered by security researcher Eugene Lim, and while the app's source code has been patched, the fix has only been made available as beta software and awaits an official release.
Azure users running Linux VMs may not be aware they have a severely vulnerable piece of management software installed on their machine by Microsoft, which can be remotely exploited in an incredibly surprising and equally stupid way. "This is a textbook RCE vulnerability that you would expect to see in the 90's -- it's highly unusual to have one crop up in 2021 that can expose millions of endpoints," Wiz security researcher Nir Ohfeld wrote.
Canonical has published Linux kernel updates for all of its supported Ubuntu releases to address several security vulnerabilities discovered in the upstream Linux kernels that could lead to privilege escalation attacks, the execurtion of arbitrary code, the exposure of sensitive information and system crash. Update now!
Recently discovered flaws impacting Linux and Windows users alike could give attackers the highest system privileges. Remediations have been released for a security shortcoming affecting all Linux kernel versions from 2014 that can be exploited by malicious users and malware already deployed on a system to gain root-level privileges.
Hackers are exploiting a dangerous privilege escalation Linux kernel security flaw known as “Dirty COW” to hijack vulnerable systems. Patch now!

Red Hat has used RPM for software package distribution for decades, but thanks to CloudLinux developer Dmitry Antipov we now know that RPM contained a nasty hidden security bug since Day One. A repair patch for this major security hole has been submitted, but Antipov fears that it may be months before the fix is released.
Canonical has released a new major Linux kernel security update for Ubuntu 21.04 (Hirsute Hippo), patching a total of 17 security vulnerabilities!
Cybersecurity researchers have disclosed a critical unpatched vulnerability affecting Pling-based free and open-source software (FOSS) marketplaces for Linux platform that could be potentially abused to stage supply-chain attacks and achieve remote code execution (RCE). This discovery highlights the fact that developers of such applications must put in a high level of scrutiny to ensure their security.
