macOS 26.x < 26.5 Multiple Vulnerabilities (127115)

Synopsis

The remote host is missing a macOS update that fixes multiple vulnerabilities

Description

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.

Solution

Upgrade to macOS 26.5 or later.
