2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack members of the community for any reason.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry will not be tolerated.
- These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudoin Windows. - No porn. Even if you watch it on a Linux machine.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

If your security relies on hidden information then it's at risk of being broken at any time by someone who will find the information in some way. Open source security is so much stronger because it works independently of system knowledge. See all the open source cryptography that secures the web for example.
Open source poc and fix increases awareness of issues and helps everyone to make progress. You will also get much more eyes to verify your analysis and fix, as well as people checking if there could other consequences in other systems. Some security specialists are probably going to create techniques to detect this kind of sophisticated attack in the future.
This doesn't happen with closed source.
If some system company/administrator is too lazy to update, the fault is on them, not on the person who made all the information available for your to understand and fix the issue.
Crowd sourcing vulnerability analysis and detection doesn’t make open source software inherently more secure.
Closed source software has its place and it isn’t inherently evil or bad.
This event shows the good and bad of the open source software world but says NOTHING about closed source software.
It does, because many more eyes can find issues, as illustrated by this story.
Closed source isn't inherently bad, but it's worse than open source in many cases including security.
I think you're the only one here thinking publishing PoC is bad.
But this issue wasn't found because of code analysis per se, but because of microbenchmarking.
That's a good point, but wasn't the micro benchmarking possible, published and analyzed because it is open source? Also the vulnerability analysis, impact analysis and fix can be peer reviewed by more yes.
