Copying my reply from another thread:

This link should be working.

Quoting from the OP tweet:

* Unauthenticated RCE vs all GNU/Linux systems (plus others) disclosed 3 weeks ago.
* Full disclosure happening in less than 2 weeks (as agreed with devs).
* Still no CVE assigned (there should be at least 3, possibly 4, ideally 6).
* Still no working fix.
* Canonical, RedHat and others have confirmed the severity, a 9.9, check screenshot.
* Devs are still arguing about whether or not some of the issues have a security impact.

I’ve spent the last 3 weeks of my sabbatical working full time on this research, reporting, coordination and so on with the sole purpose of helping and pretty much only got patronized because the devs just can’t accept that their code is crap - responsible disclosure: no more.

That’s mentioned in the article I believe. I was just trying to save some people a minute or two. :)

TLDR: Avoid Telegram and WhatsApp. Recommended messengers are Session, Signal, SimpleX and Threema. Honorable mention: Briar.
