What it is about

Das Apple iOS (vormals iPhone OS) ist das Betriebssystem für das von Apple entwickelte Smartphone iPhone, iPad und iPod Touch. Das Apple iPadOS ist das Betriebssystem für das von Apple entwickelte iPad. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Apple iOS und Apple iPadOS ausnutzen, um beliebigen Code auszuführen, Sicherheitsmaßnahmen zu umgehen, einen Denial-of-Service-Zustand herbeizuführen, vertrauliche Informationen preiszugeben, Dateien zu manipulieren oder seine Privilegien zu erweitern.

Under what conditions?

Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.

What can happen in the worst case

An attacker could use the vulnerability to

  • beliebigen Code auszuführen
  • Sicherheitsmaßnahmen zu umgehen
  • einen Denial-of-Service-Zustand herbeizuführen
  • vertrauliche Informationen preiszugeben
  • Dateien zu manipulieren oder seine Privilegien zu erweitern

Am I affected?

  • Apple iOS <16.7
  • Apple iPadOS <16.7
  • Apple iPadOS <17
  • Apple iOS <17

What helps?

Update to at least:

  • Apple iOS 16.7
  • Apple iPadOS 16.7
  • Apple iPadOS 17
  • Apple iOS 17
