More than 75% of all vulnerabilities reside in indirect dependencies:
The vast majority of security vulnerabilities in open-source projects reside in indirect dependencies rather than directly and first-hand loaded components.
"Aggregating the numbers from all ecosystems, we found more than three times as many vulnerabilities in indirect dependencies than we did direct dependencies," Alyssa Miller, Application Security Advocate at Snyk, told ZDNet in an interview discussing Snyk's State of Open Source Security for 2020 study.
The report looked at how vulnerabilities impacted the JavaScript (npm), Ruby (RubyGems), Java (MavenCentral), PHP (Packagist), and Python (PyPI) ecosystems.
Snyk said that 86% of the JavaScript security bugs, 81% of the Ruby bugs, and 74% of the Java ones impacted libraries that were dependencies of the primary components loaded inside a project.
[...] Snyk argues that companies scanning their primary dependencies for security issues without exploring their full dependency tree multiple levels down would release or end up running products that were vulnerable to unforeseen bugs.
So dear Soylentils, how do you track vulnerabilities in libraries that you use in your projects and do you scan beyond direct dependencies?

Patching and testing can be hard. You have to simultaneously fix the bug behavior while simultaneously preserving the expected behavior as much as possible. In addition, the bug can be caused by the way functions interact or round trips or library interaction or how the entire environment interacts, making it hard to track down where it actually is in the code. And, on more than a few occasions, it turns out that someone was relying on the bug behavior the whole time, non-maliciously, and didn't even realize it. This makes your test and integration suites break, which you then have to fix on top of the environment. And then, they don't want to patch it in one area and leave a bunch of other users of the software unable to update, so you have to wait for groups to be ready, despite their various release processes, to update all at the same time. Then there is also the normal human behavior of people not seeing the problem, having other priorities, dragging of feet in general, and the internal politics.

There was only one possible answer to this: throw out the library and write my own code for the needed functionality.

The checksum is good. Minimum specified version is not. It requires that you trust later versions without knowing anything about them. Which is it?
Yes, I'm relatively ignorant of go. There are lots of languages out there, and I'm not expert in most of them, perhaps any of them depending on what you mean by expert. I read the go documentation and decided that code that was written was too subject to change by people supplying the libraries. Perhaps I was wrong, but a minimum specified version is *not* reassuring. Later versions being malicious is one of the things that have gotten Javascript programs in trouble. Also, I believe, Ruby. IIRC, it once even bit Debian, though they vet the changes pretty strictly. You need to be able to specify the exact version of the library AND the checksum to be secure. Any changes need the same testing as the original version. Well, that's a bit extreme, but it's close to correct. You need a good suite of tests, and changed libraries need to pass those tests without change (including without fixing any mistakes that your test answers depend on).
There are decent arguments that all code that uses non-system libraries should be run inside of a jail, but usually need for security isn't strong enough to justify that.
All that said, this is not an ideal world, and one must make do. But there's no reason to make things worse by increasing remote dependencies. Sometimes you must, but for that to be reasonable you need to ensure that they won't change in the future. There are clear advantages to dynamic linking, but they come at the cost of lessened security. When it's links to system libraries one can say "well, if the system is 0wn3d, then there's nothing one can do", but the same doesn't apply to remote code.

Minimum specified version means it uses the oldest version that satisfies the requirements. It does the exact opposite of what you seem to be talking about. Most dep managers like pip will use use the latest version available if you specify >=2.1. If you specify "require 2.1", Go will use the minimum specified version, i.e., 2.1, unless either your package or another explicitly specifies a later version, in which case Go will use the minimum specified version that satisfies that requirement.

Can't programs require a certain version of a library?
ie: Will work with LibME > 5.4.*, 5.5?
Wouldn't that be better than having it install in a FlatPack 5.4.3? (So that if 5.4.4 comes out, the system can replace 5.4.3 and the application still run? If the application breaks with 5.4.4, it can change it's dependency accordingly)

What generally happens is the dependencies are stated like you say: 5.4 or greater. So, 5.6 comes out and has a regression in it, the dependency tree picks up 5.6 and accepts it because it's greater than 5.4, boom: your app now has the regression.
It's all wonderful theory that newer software is better, but that's far from guaranteed.
I'm not deep into the intricacies of apt / dpkg / etc. but I believe what the article is getting at is that, even if your app does place a dependency on libX 5.4 exactly, libX 5.4 may well have dependencies in its tree which are spec'ed like: libY 2.2 or greater, meaning that your libX 5.4 can still inherit a regression from libY 2.3 even though you've spec'ed it at 5.4 exactly.
It's "the price" that comes along with not reinventing the wheel. Thank dog that we've gotten away from rotating hard drives - there were layers of code in their firmware that nobody on the planet remembered how they work, yet virtually every rotating hard drive on the planet used those same layers of mystery code. Now we've got "wear leveling" code in the flash drives that is 10x more complex, but at least it was developed with slightly more modern concepts of version control.

These are all good points. I wonder how many actual infections are due to out of date libraries vs. up-to-date with regression bugs?

I wonder the same about desktop webapps that bundle their own web runtime.
But with Android, Chrome OS and Edge OS (*Windows 10) now shipping Chromium with regular security updates handled by the Chrome team, perhaps frameworks such as Electron will evolve to become lighter-weight by calling a FFI to the system runtime instead of bundling their own.

You are assuming that the updates are improvements. Sometimes, though, they can be malicious. And malicious or not they can introduce *new* bugs, that weren't in the prior version. (As well as bloat.) Every update need to go through the same analysis as the original library to ensure that it doesn't break things. If it's not externally facing, then there is rarely a case that a working program is improved by a library change. And if the library isn't distributed with the program, the library can *become* an attack surface.

Some of it is definitely self inflicted.
It's certainly possible to have too many dependencies, but most projects have mostly dependencies they need. If you didn't need the dependency, there's probably no code path that invokes it, so its bugs likely don't matter. It's bloat, but not dangerous.
Doing everything yourself is a practical impossibility, especially in the Java and Node ecosystems. You wouldn't accomplish anything anyway, you would just write your own bugs.
Some companies have cultures or policies that make it extremely difficult to update things that need to be updated. "If you update a dependency," they say, "we have to test everything from scratch! We can't afford to do that." This is an example of management making things difficult whenever they can see them. Some companies will let you update your application dependencies, but not the operating system. This is not any better.
The solution is simply for management to realize that a bug that happens because you didn't update things is not better than a bug that happens because you did update things. Not only are bugs more numerous in outdated code, they're also more dangerous.
The policy needs to be "every release you update all the dependencies unless something breaks," not "you never update anything until you absolutely have to." Sometimes you will have bugs as a result, but you were going to have bugs anyway.

Of the projects they examined, what percent of the entire code base was made up of code from indirect dependencies?
Means something very different if 10% of the codebase contained 75% of the bugs, as opposed to 80% of the codebase contained 75% of the bugs.

No, it doesn't. The metric they gave is irrelevant. It's bugs from indirect dependencies vs bugs from direct dependencies - without clarifying anything about coverage. The one example they give is in the article itself which states:
In which case about 99% of your bugs being in dependencies would not be anything particularly meaningful.

I imagine every indirect dependency of one project is going to be a direct dependency of an intermediate project, so I find their statement a bit strange.
TFA is clearly focused on web technologies so I suppose the projects they're interested in are mainly websites and web applications. It's directed at web businesses. For API developers, I think the vulnerabilities will be in their direct dependencies, so I guess it becomes a question of who is responsible for identifying, reporting, and patching these vulnerabilities.

This is why I'm very wary of package managers for languages, especially in a professional setting. The only one that seems to do a decent job is Rust's cargo, because it builds from source, but even that's not foolproof or secure.
That said, Python's pip is definitely easy, and sometimes that's all you need. However, it's definitely not something you should rely upon.
As for the horrors of npm and JavaScript, that entire pile of trash is so noxious that I won't touch it at all. May it fry in hell for all eternity.

Agree. They're usable for rapid development but the dependency chain becomes too large, too quickly. This is also a problem for linux distros, I have gtk libs on a headless server as dependencies of graphviz that was required for the documentation of something I was asked to build from source. The clusterfuck is real!
They're tools. I've been having fun with a small nim project by compiling to js and running in quickjs.

A vulnerability in a 3rd tier dependency does not immediately equate to a vulnerability in the application (or 2nd tier dependency for that matter). If you go into the analysis with that mindset, naturally you will find that a single vuln in a core library *may* affect many projects, but this is a meaningless metric. They basically measured how often core libraries are used and have an identified vulnerability.
As a security researcher I'd rather look at code that is commonly used by everyone rather than a project that only has a dozen downloads.
Don't version lock your code, fix how your code uses APIs that change over time and rebuild often.

Oh bullshit. When counting mobile devices, their market share is down around 30% and that's not enough to command monopoly rents. They've lost the server market, like they lost the phone market, if Netcraft is any indicator. It shows around 4.5% and declining. They're betting what's left of their farm on Azure, but Azure continues to lose money [medium.com] and pretty soon the FTC will have to step in and address the shell game going on.
Azure has to market Free and Open Source software, but it has only become part of their marketing because it is the only way they can even attempt to bring Azure into relevancy. While that is going on, they've increased their attacks against Copyleft via Snyk, Blackduck, and other proxies. Their use of proxies for software patent attacks has only increased. The whole indemnification scam they have for Azure is about baiting patent trolls (NPEs) to buy patents from them in exchange for a contract prohibiting going after the one or two Azure customers out there. Don't underestimate the harm and cost caused by the use of software patents.
