This update patches three already exploited vulnerabilities:
(1) CVE-2023-41993 Remote code execution in WebKit. This could be used as an initial access vector
(2) CVE-2023-41992 Privilege Escalation. A follow-up after the initial access was achieved via the first vulnerability
(3) CVE-2023-41991 Certificate Validation Issue. A malicious app installed via 1 and 2 may be more difficult to detect due to this vulnerability

Patches are available for all currently supported operating systems and Safari to address the WebKit vulnerability.

iOS 17 (just released this week), as well as iOS 16, is vulnerable.

CVSS numbers below are not "official" but generated with some help from ChatGPT based on the vulnerability description. Used them as rough indicators of severity.

Enter comment here... a fake TeamViewer page, and that page led to a different type of malware. This week's infection involved a downloaded JavaScript (.js) file that led to Microsoft Installer packages (.msi files) containing other script that used free or open source programs.
distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
