Long elapse of time
Interesting the this vulnerability didn't have similar attributes as other vulnerabilities. Otherwise I feel vulnerability scanners would have picked this up in a 20 year span.

I know in the article this states that the hole is fixed in the next security release, but is there anyone with outside knowledge of the vulnerability know what changes were made to effectively close the hole?

Re: Long elapse of time
This isn't the first open-source vuln and it won't be the last, for sure. Patching is always a headache, but even moreso when an open source tool is used in so many places and in so many iterations. Some products won't ever get patched, and many users won't even know their product (based on whatever vulnerable open source tool) is at risk. No easy solutions here.

Perhaps not actually reachable in the real world
The severity of this issue needs to be tempered with the evaluation that most products do not ship with a configuration that allows the issue to be triggered:

Re: Perhaps not actually reachable in the real world
Indeed, it doesn't mean every single LZO implementation is affected. As Bailey says, each implementation needs to be evaluated for the flaw.

Re: Perhaps not actually reachable in the real world
Very true. Has there been any documentation/data on how to scan for this and what tools would be the most efficient to do so?

I am sure vulnerability scanners  would be able to but thus far has there been any that have stepped up to say that they can quickly and passively scan for this? Or has this been dismissed because the quantity of people this could effect has been difficult to calculate?

Re: Perhaps not actually reachable in the real world
That's a great question. There wasn't any specific guidance thus far on how to scan for it, but the recommendation was to update any apps that use the affected libraries, all of which now have patches. Don Bailey is planning to provide more details on the vuln beyond his initial post, so maybe we'll see more detection info there.

How Machine Learning, AI & Deep Learning Improve Cybersecurity
Machine intelligence is influencing all aspects of cybersecurity. Organizations are implementing AI-based security to analyze event data using ML models that identify attack patterns and increase automation. Before security teams can take advantage of AI and ML tools, they need to know what is possible.
