Apple: iPhone update also fills critical vulnerabilities

MacWorld’s report also shows that Apple has also closed two important vulnerabilities with the latest patch. These are initially called zero-day exploits that were only discovered after they had already been exploited by attackers. For example, hackers can use this to access information from the operating system.

Apple itself writes that this specifically represents a vulnerability in the AppleAVD component. In principle, attackers can use these “to execute malicious code with kernel rights”. Another vulnerability that was closed with the update allowed websites to access sensitive user information.
