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

  - A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia     15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.5. A malicious app may be able to break out of its sandbox.
    (CVE-2026-28978)

  - The issue was addressed with improved checks. This issue is fixed in iOS 18.7.9 and iPadOS 18.7.9, macOS     Sequoia 15.7.7, macOS Tahoe 26.5. Processing a maliciously crafted file may lead to a denial-of-service or     potentially disclose memory contents. (CVE-2026-28941)

  - An access issue was addressed with additional sandbox restrictions. This issue is fixed in macOS Sequoia     15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.2. An app may be able to break out of its sandbox.
    (CVE-2025-43524)

  - 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 permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia     15.7.7, macOS Sonoma 14.8.7, macOS Tahoe 26.4. An app may be able to gain root privileges.
    (CVE-2026-28840)
