And Debian 10 received a kernel security update. Check out what’s new and find out how to update your Debian system.
The Debian Project is an association of individuals who have created common cause to create a free operating system. This operating system is called Debian.
Currently, Debian systems use the Linux kernel. Linux is completely free software started by Linus Torvalds and supported by thousands of programmers around the world.
Of course, what people want is application software: programs to help them get what they want to do, from editing documents, running a business, running games, to creating more software.
Debian comes with over 50,000 packages (pre-compiled software that is packaged in a nice format for easy installation on your machine) – all of it free.
It’s a bit like a tower. At the base is the kernel. In addition are all the basic tools. Next is all the software you run on your computer.
At the top of the tower is Debian – carefully organizing and tweaking everything so that everything works together.
Now, the Debian Project has released a new Linux kernel security update for its Debian 10 operating system series, to address several security issues.
The new Linux kernel security update arrives about three months after the previous kernel update and is here to address a total of four security vulnerabilities discovered by various security researchers in the upstream 4.19 Linux kernel series used by the Debian 10 operating system .
The four security holes fixed in this kernel update are CVE-2020-36311 , a vulnerability discovered in the KVM subsystem for AMD CPUs that could allow an attacker to cause a denial of service (soft crash), triggering the destruction of a large secure crypt Virtualization Virtual Machine (SEV).
The second vulnerability fixed is CVE-2021-3609 , a race condition reported by Norbert Slusarek in the Linux kernel CAN BCM network protocol that could allow a local attacker to escalate their privileges.
The third security issue addressed by the new Debian Buster kernel update is CVE-2021-33909 , a 7-year privilege escalation flaw discovered by Qualys Research Labs in the file system layer of the Linux kernel, which may allow an unprivileged user creates, mounts, and then deletes a large directory structure greater than 1 GB in size.
Finally, the new Debian Buster kernel update fixes CVE-2021-34693 , an information leak discovered by Norbert Slusarek in the Linux kernel’s CAN BCM network protocol, which could allow a local attacker to obtain sensitive information from the Linux kernel’s memory. kernel stack.
The Debian Project asks all users of the Debian 10 Buster operating system series to update their kernel packages to version 4.19.194-3 as soon as possible, which will fix all of the above security issues. Note that after installing the new kernel version, you need to reboot your computer.
In related news, the Debian Project also today released a security update for the systemd package to address CVE-2021-33910 , a memory corruption vulnerability discovered by Qualys Research Labs where an attacker-controlled allocation using the alloca() function could lock systemd and the entire operating system.
