Also, let’s take a look at the Microsoft Patch Tuesdays vulnerabilities, Linux Patch Wednesdays vulnerabilities and some other interesting vulnerabilities that have been released or updated in the last 3 months. Finally, I’d like to end this episode with a reflection on how my 2023 went and what I’d like to do in 2024.

October was an interesting and busy month for me. I started a new job, worked on my open source Vulristics project, and analyzed vulnerabilities using it. Especially Linux vulnerabilities as part of my new Linux Patch Wednesday project. And, of course, analyzed Microsoft Patch Tuesday as well. In addition, at the end of October I was a guest lecturer at MIPT/PhysTech university. But first thing first.

September was quite a busy month for me.
Continue readingScanvus now supports Vulners and Vulns.io VM Linux vulnerability detection APIs. Hello everyone! Great news for my open source Scanvus project! You can now perform vulnerability checks on Linux hosts and docker images not only using the Vulners.com API, but also with the Vulns.io VM API. It’s especially nice that all the code to support the new API was written and contributed by colleagues from Vulns.io. I just had to do the final test. Many thanks to them for this!

Scanvus – my open source Vulnerability Scanner for Linux hosts and Docker images. Hello everyone! This video was recorded for the VMconf 22 Vulnerability Management conference, vmconf.pw. I will be talking about my open source project Scanvus. This project is already a year old and I use it almost every day.

Scanvus (Simple Credentialed Authenticated Network VUlnerability Scanner) is a vulnerability scanner for Linux. Currently for Ubuntu, Debian, CentOS, RedHat, Oracle Linux and Alpine distributions. But in general for any Linux distribution supported by the Vulners Linux API. The purpose of this utility is to get a list of packages and Linux distribution version from some source, make a request to an external vulnerabililty detection API (only Vulners Linux API is currently supported), and show the vulnerability report.
Scanvus can show vulnerabilities for
This utility greatly simplifies Linux infrastructure auditing. And besides, this is a project in which I can try to implement my ideas on vulnerability detection.
For all targets the output is the same. It contains information about the target and the type of check. Then information about the OS version and the number of Linux packages. And finally, the actual information about vulnerabilities: how many vulnerabilities were found and the criticality levels of these vulnerabilities. The table shows the criticality level, bulletin ID, CVE list for the bulletin, and a comparison of the invulnerable fixed package version with the actual installed version.
This report is not the only way to present results. You can optionally export the results to JSON (OS inventory data, raw vulnerability data from Vulners Linux API or processed vulnerability data).
End of CentOS Linux. Where to migrate? Hello everyone! As you probably know, CentOS Linux, the main Enterprise-level Linux server distribution, will soon disappear. It wasn’t hard to predict when RedHat acquired CentOS in 2014, and now it is actually happening. End of life of CentOS Linux 8 was 31.12.2021. There won’t be CentOS Linux as downstream for RedHat anymore. Only CentOS Stream, that will be upstream for RedHat, more or less a testing distro like Fedora.
Of course, it is a matter of debate whether security guys can actually decide which Linux distributions a company will use and set that as a requirement. But in any case, the security guys will definitely take part in the decision. I made a poll in my Telegram channel. 113 people voted. So, let’s take a look at the results and discuss which of the Linux distributions we can recommend to IT teams.
