Apple Patches Exploited Vulnerabilities in iOS/iPadOS, macOS, watchOS and Safari
Apple released iOS, macOS, and watchOS updates, patching three vulnerabilities already being exploited. Two vulnerabilities affect WebKit, leading to a Safari patch for older operating systems.
The two WebKit issues (CVE-2023-32439 and CVE-2023-32435) can be used to execute arbitrary code as a user visits a malicious web page. The third vulnerability, CVE-2023-32434, can be used to elevate privileges after the initial code execution.
See below for affected operating systems. Apple does not provide CVSS scores, so we asked ChatGPT to fill them in.
| Safari 16.5.1 | iOS 16.5.1 and iPadOS 16.5.1 | iOS 15.7.7 and iPadOS 15.7.7 | macOS Ventura 13.4.1 | macOS Monterey 12.6.7 | macOS Big Sur 11.7.8 | watchOS 9.5.2 | watchOS 8.8.1 |
|---|---|---|---|---|---|---|---|
| CVE-2023-32439 [critical] ChatGPT-CVSS: CVSS score: 9.8 (Critical) *** EXPLOITED *** WebKit A type confusion issue was addressed with improved checks.
