⚡ TL;DR | Go Straight to the Apple Vulnerability Audit Report

Apple has released 3 new security updates for iOS, iPadOS, macOS Sonoma, and Safari in response to new zero-day 2 vulnerabilities. These vulnerabilities are already being exploited in the wild against older iOS systems. When successfully exploited, these flaws could lead to arbitrary code execution or disclosure of sensitive information. We have added a new report to Lansweeper to help you locate vulnerable devices.

Apple Vulnerabilities CVE-2023-42916 and CVE-2023-42917

CVE-2023-42916 is an out-of-bounds read issue in the WebKit browser engine. When exploited, the issue could cause sensitive data to be disclosed when processing web content. CVE-2023-42917 is a memory corruption bug, also in WebKit, that could allow an attacker to execute arbitrary code. This can again compromise sensitive data or disrupt operations. For more information, please consult Apple’s Security Release page.

Apple is aware that these vulnerabilities are already being exploited in the wild against versions of iOS before 16.7.1, the iOS version released in October 2023. They have not released any further information regarding the exploitation. However, Google TAG researchers have found that similar zero-days have been used in spyware attacks against high-risk individuals.
