What it is about
Apple macOS ist ein Betriebssystem, das auf FreeBSD und Mach basiert. Ein Angreifer kann mehrere Schwachstellen in Apple macOS Sonoma, macOS Sequoia und macOS Tahoe ausnutzen, um seine Privilegien zu erhöhen, um einen Denial of Service Angriff durchzuführen, um Informationen offenzulegen, um beliebigen Programmcode auszuführen, und um Sicherheitsvorkehrungen zu umgehen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- seine Privilegien zu erhöhen
- einen Denial of Service Angriff durchzuführen
- Informationen offenzulegen
- beliebigen Programmcode auszuführen
- Sicherheitsvorkehrungen zu umgehen
Am I affected?
