There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A Content Security Policy bypass was addressed with improved enforcement in AudioWorklet contexts. This
    issue is fixed in Safari 26.5, iOS 18.7.9 and iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Tahoe 26.5.
    Processing maliciously crafted web content may bypass Content Security Policy. (CVE-2026-43670)

The version of Apple iOS running on the mobile device is prior to 26.5. It is, therefore, affected by multiple vulnerabilities.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A Content Security Policy bypass was addressed with improved enforcement in AudioWorklet contexts. This     issue is fixed in Safari 26.5, iOS 18.7.9 and iPadOS 18.7.9, iOS 26.5 and iPadOS 26.5, macOS Tahoe 26.5.
    Processing maliciously crafted web content may bypass Content Security Policy. (CVE-2026-43670)

Note that Nessus relies on the presence of the package as reported by the vendor.

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 Debian 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-6534 advisory.

    Several vulnerabilities have been discovered in the WebKitGTK web     engine, that may lead to heap corruption, local privilege escalation,     remote code execution, out-of-bounds memory access, cross-origin data     leak and sandbox escape, among other problems.

    See the WebKitGTK security advisory for details on each vulnerability:
    https://webkitgtk.org/security/WSA-2026-0006.html

    For the stable distribution (trixie), these problems have been fixed in     version 2.54.0-1~deb13u1.

    We recommend that you upgrade your webkit2gtk packages.
