How do you track security vulnerabilities?

I do regular automated updates. For anything requiring human intervention like the xz thing I trust Lemmy and YouTube to keep me updated. No dedicated news source because if I were to freak out about every new vulnerability found I wouldn't be able to sleep at night.

Mailing list provided by my distro. https://lists.debian.org/debian-security-announce/

Fediverse and RSS mostly.

My distribution (archlinux) notifies of critical vulnerabilities that require user action. There's a news mailing list.

After that I rely on social network (Mastodon mostly) or lemmy for news, as vulnerabilities often get some conversation. Apart from that, software i'm really interested in I also follow through RSS so I get news when they update for their vulnerabilities -that is when the vulnerabilities are not self inflicted as the xz case-.

I didn't really consider that there are feeds for such things, especially for my distro(s). Embarrassing, but it means you helped making me safer!

I'm now subscribed to the Debian security list, seeing as all my servers run Debian. I just had unattended upgrades with Mail logs before.

I tend to find out about vulnerabilities before it hits the news outlets from the rss feed at https://seclists.org/oss-sec/

Other than that, I've got a bunch of other security feeds I follow and also have automated updates with just about everything.

I rely on notifications from glsa-check or my distro's package manager. I was notified about a problem with xz-utils on Thursday evening, but didn't see anyone post about it until Friday morning.

glsa-check is a command-line tool included with the gentoolkit package in Gentoo Linux. Its primary function is to scan your system for installed packages that are vulnerable according to Gentoo Linux Security Advisories (GLSAs). GLSAs are official notifications from the Gentoo security team about security vulnerabilities that affect packages in the Gentoo repository.

Seeing my colleagues, I fear that the answer from them is "That's the neat part, you don't!"

the worst ones end up on https://slashdot.org/ e.g.:

https://m.slashdot.org/story/426644

I read it like twice per day. However, my software updates should fix most automatically without me even knowing what was going on.

i subscribed for fedora mailist a few days ago and their talk awas helpful for me to notice that i was one of the affected, just subscribe to your distro blog/mail/etc

I just use unattended-upgrades and forget about it

You can watch rss feeds to follow all CVEs like Microsoft’s https://api.msrc.microsoft.com/update-guide/rss

NIST used to have an rss feed for CVEs but deprecated it recently. They still have other ways you can follow it though https://nvd.nist.gov/vuln/data-feeds

Or if you just want to follow CVEs for certain applications you can host/subscribe to something like https://www.opencve.io/welcome which allows you to filter CVEs from NIST’s National Vulnerability Database (NVD)

Found out about the xz one on Lemmy. Years ago I was briefly subscribed to Bugtraq but that was too much. Now I'm subscribed to a few OS specific security announcement mailing lists.

https://oss-security.openwall.org/subscribe

Used to follow the RHEL security lists but they recently retired those as well. Could really use a replacement.

I rely on Lemmy and in pacman -Syyu everyday

For Ubuntu, I use https://ubuntu.com/security/oval

Mainly Phoronix and Lemmy.

I don't. I run software whose maintainers I trust to provide regular security updates.

Of course there's some software I have installed that doesn't fit that criteria. But I also minimize my attack surface by exposing the bare minimum and enabling extra security features where I can.

Your distro should havê a security mailing list you van subscribe to

I'm subscribed to https://bugalert.org/ RSS feeds, but it seems they haven't had any activity since October last year.

Does anyone know what happened to them?

Lucky I only have to worry about ones from Cisco or FortiNet and both have RSS feeds that I have linked into Slack at work to tell us when a new patch is out or a new psirt is released.

I actually have automated security updates on all my servers. Also in general i run greenbone at home that does daily scans of all the VLANS/networks I have at home.
