The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.5. It is, therefore, affected by multiple vulnerabilities:

  - A specially-crafted file can cause libjxl's decoder to write pixel data to uninitialized unallocated     memory. Soon after that data from another uninitialized unallocated region is copied to pixel data. This     can be done by requesting color transformation of grayscale images to another grayscale color space.
    Buffers allocated for 1-float-per-pixel are used as if they are allocated for 3-float-per-pixel. That     happens only if LCMS2 is used as CMS engine. There is another CMS engine available (selected by build     flags). (CVE-2026-1837)

  - When doing multi-threaded LDAPS transfers (LDAP over TLS) with libcurl, changing TLS options in one thread     would inadvertently change them globally and therefore possibly also affect other concurrently setup     transfers. Disabling certificate verification for a specific transfer could unintentionally disable the     feature for other threads as well. (CVE-2025-14017)

  - When doing TLS related transfers with reused easy or multi handles and altering the     `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally reuse a CA store cached in memory for     which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could     make libcurl find and accept a trust chain that it otherwise would not. (CVE-2025-14819)

  - An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in iOS     18.7.9 and iPadOS 18.7.9, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5. An app may be able     to execute arbitrary code with kernel privileges. (CVE-2026-28819)

  - A buffer overflow was addressed with improved bounds checking. This issue is fixed in iOS 18.7.9 and     iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5, tvOS     26.5, visionOS 26.5, watchOS 26.5. A remote attacker may be able to cause unexpected app termination.
    (CVE-2026-28846)

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 15.8. It is, therefore, affected by multiple vulnerabilities:

  - A heap-based buffer overflow vulnerability was found in Samba within the GSSAPI unwrap_des() and     unwrap_des3() routines of Heimdal. The DES and Triple-DES decryption routines in the Heimdal GSSAPI     library allow a length-limited write buffer overflow on malloc() allocated memory when presented with a     maliciously small packet. This flaw allows a remote user to send specially crafted malicious data to the     application, possibly resulting in a denial of service (DoS) attack. (CVE-2022-3437)

  - A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Tahoe 26.5.
    An app may be able to access protected user data. (CVE-2026-28930)

  - A use after free issue was addressed with improved memory management. This issue is fixed in iOS 18.7.9     and iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5,     tvOS 26.5, visionOS 26.5, watchOS 26.5. An app may be able to cause unexpected system termination.
    (CVE-2026-28969)

  - A permissions issue was addressed by removing the vulnerable code. This issue is fixed in macOS Sequoia     15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6. An app may be able to read files outside of its sandbox.
    (CVE-2026-43763)

  - The issue was addressed with improved bounds checks. This issue is fixed in iOS 26.6 and iPadOS 26.6,     macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, watchOS 26.6. Processing a maliciously crafted file may lead     to unexpected app termination. (CVE-2026-64758)
