iOS 17.1.2 brings fixes for Critical iPhone Security Flaws

iOS 17.1.2 patches Critical iPhone Security Flaw

Apple has released iOS 17.1.2, bringing fixes for two zero-day vulnerabilities for iPhone and iPad users.

The flaws revolve around Apple’s WebKit and the exploits involving the vulnerabilities show attackers continue to focus on finding flaws in the framework that downloads and presents web-based content.

The latest bugs could lead to both data leakage and arbitrary code execution, and appear to be tied to targeted attacks that are common against high-risk users.

The vulnerabilities — CVE-2023-42916 and CVE-2023-42917 — were discovered by Clément Lecigne of Google’s Threat Analysis Group and affect iPhone XS and later; several models of iPads; and Macs running macOS Monterey, Ventura or Sonoma.

Apple is aware of a report that this issue may have been exploited against versions of iOS before iOS 16.7.1.
