A buffer overflow issue was addressed with improved memory handling. This issue is fixed in iOS 26.5 and iPadOS 26.5, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.5, tvOS 26.5, watchOS 26.5. Processing a maliciously crafted image may corrupt process memory.

The remote host is running a version of macOS / Mac OS X that is 15.x prior to 15.7.8. It is, therefore, affected by multiple vulnerabilities:

  - The issue was addressed with improved input sanitization. This issue is fixed in iOS 26.5.2 and iPadOS     26.5.2, macOS Tahoe 26.5.2. An app may be able to cause unexpected system termination or write kernel     memory. (CVE-2026-43724)

  - This issue was addressed with improved input validation. This issue is fixed in iOS 26.5.2 and iPadOS     26.5.2, macOS Tahoe 26.5.2. An app may be able to cause unexpected system termination or corrupt kernel     memory. (CVE-2026-39868)

  - An access issue was addressed with additional sandbox restrictions. This issue is fixed in macOS Tahoe 26.
    An app may be able to access sensitive user data. (CVE-2025-43325)

  - Double Free and possible RCE vulnerability in Apache HTTP Server with the HTTP/2 protocol. This issue     affects Apache HTTP Server: 2.4.66. Users are recommended to upgrade to version 2.4.67, which fixes the     issue. (CVE-2026-23918)

  - A logic issue was addressed with improved file handling. This issue is fixed in macOS Tahoe 26.5. A     maliciously crafted ZIP archive may bypass Gatekeeper checks. (CVE-2026-28914)

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 14.x prior to 14.8.8. It is, therefore, affected by multiple vulnerabilities:

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

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)

  - An information leakage was addressed with additional validation.
