A denial-of-service issue was addressed with improved input validation. This issue is fixed in macOS Tahoe 26.1. Visiting a website may lead to an app denial-of-service.

The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.1. It is, therefore, affected by multiple vulnerabilities:

  - A memory corruption issue was addressed with improved lock state checking. This issue is fixed in iOS     18.7.2 and iPadOS 18.7.2, iOS 26.1 and iPadOS 26.1, macOS Sequoia 15.7.2, macOS Sonoma 14.8.2, macOS Tahoe     26.1, tvOS 26.1, visionOS 26.1, watchOS 26.1. A malicious application may cause unexpected changes in     memory shared between processes. (CVE-2025-43510)

  - Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host     nor ALL, allows listed users to execute commands on unintended machines. (CVE-2025-32462)

  - REXML is an XML toolkit for Ruby. The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML     that has many deep elements that have same local name attributes. If you need to parse untrusted XMLs with     tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other     parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected. The REXML     gem 3.3.6 or later include the patch to fix the vulnerability. (CVE-2024-43398)

  - REXML is an XML toolkit for Ruby. The REXML gem before 3.3.9 has a ReDoS vulnerability when it parses an     XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does     not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or     later include the patch to fix the vulnerability. (CVE-2024-49761)

  - A permissions issue was addressed with improved validation. This issue is fixed in iPadOS 17.7.6, macOS     Sequoia 15.4, macOS Sequoia 15.7.2, macOS Sonoma 14.7.5, macOS Sonoma 14.8.2, macOS Tahoe 26.1, macOS     Ventura 13.7.5. A shortcut may be able to access files that are normally inaccessible to the Shortcuts     app. (CVE-2025-30465)

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

The remote host is running a version of macOS / Mac OS X that is 15.x prior to 15.7. It is, therefore, affected by multiple vulnerabilities:

  - This issue was addressed with additional entitlement checks. This issue is fixed in macOS Sequoia 15.7,     macOS Sonoma 14.8, macOS Tahoe 26. An app may be able to access sensitive user data. (CVE-2025-43308)

  - A buffer-overread issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and     3.1.x through 3.1.4. The ungetbyte and ungetc methods on a StringIO can read past the end of a string, and     a subsequent call to StringIO.gets may return the memory value. 3.0.3 is the main fixed version; however,     for Ruby 3.0 users, a fixed version is stringio 3.0.1.1, and for Ruby 3.1 users, a fixed version is     stringio 3.0.1.2. (CVE-2024-27280)

  - A logic issue was addressed with improved checks. This issue is fixed in macOS Sequoia 15.7, macOS Sonoma     14.8, macOS Tahoe 26. An app may be able to access sensitive user data. (CVE-2025-24197)

  - An authorization issue was addressed with improved state management. This issue is fixed in iOS 26 and     iPadOS 26, macOS Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26, tvOS 26, watchOS 26. An app may be able     to access sensitive user data. (CVE-2025-31255)

  - A privacy issue was addressed with improved checks. This issue is fixed in macOS Sequoia 15.5, macOS     Sequoia 15.7, macOS Sonoma 14.8, macOS Tahoe 26. An app may be able to capture a screenshot of an app     entering or exiting full screen mode. (CVE-2025-31259)
