Google Chrome 89.0.4389.72 fixt ausgenutzte 0-day-Schwachstelle

[English]Google hat bereits zum 2. März 2021 den Google Chrome 89.0.4389.72 freigegeben. Der Browser sollte zeitnah aktualisiert werden, da Google eine aktiv ausgenutzte 0-day-Schwachstelle (die 2. in 2021) schließt. Ergänzung: Die Google Entwickler wollen künftig alle 4 Wochen eine neue Version des Browsers freigeben.

Mir ist die Information hier unter die Augen gekommen. Im Google-Blog gibt es diesen Beitrag mit einer Liste der im Chrome 89.0.4389.72 für den Desktop geschlossenen Schwachstellen. Hier einige hervorgehobene Schwachstellen, die beseitigt wurden.

Ein Teil der Schwachstellen ist mit der Einstufung High versehen. Google schreibt, dass ein Exploit für CVE-2021-21166 in freier Wildbahn existiert.  Weitere Probleme wurden intern durch Audits und Fuzzing aufgespürt und behoben. Der Browser sollte also zügig aktualisiert werden. Die Chrome-Version für Windows, Mac und Linux wird in den nächsten Tagen über die automatische Update-Funktion auf die Systeme ausgerollt. Sie können diese Build aber auch hier herunterladen.

Ergänzung: Die Google Entwickler wollen künftig alle 4 Wochen eine neue Version des Browsers freigeben. Dies wurde im Chromium-Blog angekündigt.
