Synopsis

The remote host is missing a macOS update that fixes multiple vulnerabilities

Description

The remote host is running a version of macOS / Mac OS X that is 14.x prior to 14.8.4. It is, therefore, affected by multiple vulnerabilities:

 - The issue was addressed with improved memory handling. This issue is fixed in macOS Tahoe 26.1. An app may be able to cause unexpected system termination or corrupt process memory. (CVE-2025-43402)

 - An out-of-bounds access issue was addressed with improved bounds checking. This issue is fixed in macOS Tahoe 26, macOS Sonoma 14.8.2. Processing a maliciously crafted media file may lead to unexpected app termination or corrupt process memory. (CVE-2025-43338)

 - Multiple memory corruption issues were addressed with improved input validation. This issue is fixed in watchOS 26.2, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, visionOS 26.2, tvOS 26.2. A malicious HID device may cause an unexpected process crash. (CVE-2025-43533)

 - A logic issue was addressed with improved validation. This issue is fixed in macOS Tahoe 26.2. An app may be able to access sensitive user data. (CVE-2025-46283)

 - libexpat in Expat before 2.7.2 allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing. (CVE-2025-59375)

Note that Nessus has not tested for these issues but has instead relied only on the operating system's self-reported version number.

Solution

Upgrade to macOS 14.8.4 or later.
