Apple Patches Exploited WebKit Vulnerabilities in iOS/iPadOS/macOS
Apple today released patches for two WebKit vulnerabilities affecting macOS, iPadOS and iOS. I would expect standalone Safari updates for older macOS versions in the future. At this point, only the most recent operating system versions received patches.
The vulnerabilities have been exploited against versions of iOS before 16.7.1. iOS 16.7.2 is the latest iOS 16 release, released in late October. It is not clear if it is vulnerable. Apple just states which versions were successfully exploited.
| iOS 17.1.2 and iPadOS 17.1.2 | macOS Sonoma 14.1.2 |
|---|---|
| CVE-2023-42916 [moderate] WebKit An out-of-bounds read was addressed with improved input validation. Processing web content may disclose sensitive information. Apple is aware of a report that this issue may have been exploited against versions of iOS before iOS 16.7.1. |
