In this kind of situation it’s the developers that we need to be talking to. If it’s possible to connect with them and discuss issues like this, they should be asked to look into it and do whatever is necessary to fix the bug.
The entire reason this spammy "article" was written was off the back of a tweet from Pieter Wuille, who has been developing and working on Bitcoin Core since 2011 and who has the third most commits to the repository on GitHub. The devs are well aware of this bug, and it will be fixed when necessary.
Imagine that those who discovered the bug decides to keep calm and say nothing about it, those developers in the future wouldn’t know about it and by the time they might get to realize it, it might be late to fix.
If a two-bit spam site like Coindesk is aware of a bug in bitcoin's code, you can bet every last satoshi you own that the devs have been aware of it for far longer.
