The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.0. It is, therefore, affected by multiple vulnerabilities:

  - There exists a vulnerability in SQLite versions before 3.50.2 where the number of aggregate terms could     exceed the number of columns available. This could lead to a memory corruption issue. We recommend     upgrading to version 3.50.2 or above. (CVE-2025-6965)

  - 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)

  - The issue was addressed with improved input sanitization. This issue is fixed in macOS Sequoia 15.5. An     app may be able to gain elevated privileges. (CVE-2025-31259)

  - Perl threads have a working directory race condition where file operations may target unintended paths. If     a directory handle is open at thread creation, the process-wide current working directory is temporarily     changed in order to clone that handle for the new thread, which is visible from any third (or more) thread     already running. This may lead to unintended operations such as loading code or accessing files from     unexpected locations, which a local attacker may be able to exploit. The bug was introduced in commit     11a11ecf4bea72b17d250cfb43c897be1341861e and released in Perl version 5.13.6 (CVE-2025-40909)

  - A configuration issue was addressed with additional restrictions.
