@cstrotm Bind 9 Revolver be like: PENG IN A 127.0.0.1
Carsten Strotmann20h ago

es gibt neue BIND 9 Versionen, in denen wurden Sicherheitsprobleme vorheriger Versionen gefixed:

https://kb.isc.org/docs/cve-2026-1519
https://kb.isc.org/docs/cve-2026-3104
https://kb.isc.org/docs/cve-2026-3119
https://kb.isc.org/docs/cve-2026-3591

u.a. Denial-of-Service bei BIND 9 Revolvern (CPU-Auslastung, Speicherauslastung, Crash).

Die ISC-Repositories haben die neuen Versionen

- 9.18.47
- 9.20.21

Ich empfehle ein Update, sobald die neuen BIND 9 Versionen in den Repositories der Linux-Distribution verfügbar ist.

Beim nächsten VCFe ziemlich sicher nicht in der Ausstellung zu sehen, aber vielleicht bei einer der Exkursionen in die datArena München: MIPS R6000 CPUs. Ausgeführt in stromhungriger aber schneller ECL-Technik. Das Foto zeigt das CPU-Board eines Control Data 4680 Servers aus 1990, betrieben unter den Unix-Derivat EP/IX. #VCFe #VCFe25.0 #vintagecomputing #mips #r6000 #ecl #controldata

Here is a fun thing. I work for Vivaldi Browser. Load any of our websites and you see no cookie banner and no mention of partners.

"But wait" you say, "didn't those terrible Europeans mandate the cookie banner!?"

No, no they did not. We do not need a cookie banner because we are not selling all your shit to every company under the sun.

Also those sites with cookie banners are just doing malicious compliance. This was never about the EU requiring cookie banners!

It’s a web browser. But fun. It comes with a bunch of clever features built-in. It’s super flexible and does not track you. Get the Vivaldi browser for desktop, mobile, and your car!

Does anyone run the YADIFA DNS Server (https://yadifa.eu/) in production? I would be interested in stories about this piece of open source software. How widespread is it deployed?
