A downgrade issue affecting Intel-based Mac computers was addressed with additional code-signing restrictions. This issue is fixed in macOS Sequoia 15.7.3, macOS Tahoe 26.2. An app may be able to access user-sensitive data.

The remote host is running a version of macOS / Mac OS X that is 26.x prior to 26.2. It is, therefore, affected by multiple vulnerabilities:

  - A vulnerability has been identified in the libarchive library. This flaw can be triggered when file     streams are piped into bsdtar, potentially allowing for reading past the end of the file. This out-of-     bounds read can lead to unintended consequences, including unpredictable program behavior, memory     corruption, or a denial-of-service condition. (CVE-2025-5918)

  - libcurl's ASN1 parser code has the `GTime2str()` function, used for parsing an ASN.1 Generalized Time     field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the
    *time fraction*, leading to a `strlen()` getting performed on a pointer to a heap buffer area that is not     (purposely) null terminated. This flaw most likely leads to a crash, but can also lead to heap contents     getting returned to the application when     [CURLINFO_CERTINFO](https://curl.se/libcurl/c/CURLINFO_CERTINFO.html) is used. (CVE-2024-7264)

  - Incorrect security UI in Downloads in Google Chrome prior to 129.0.6668.58 allowed a remote attacker who     convinced a user to engage in specific UI gestures to perform UI spoofing via a crafted HTML page.
    (Chromium security severity: Medium) (CVE-2024-8906)

  - Out of bounds memory access in ANGLE in Google Chrome on Mac prior to 143.0.7499.110 allowed a remote     attacker to perform out of bounds memory access via a crafted HTML page. (Chromium security severity:
    High) (CVE-2025-14174)

  - The issue was addressed with improved handling of caches. This issue is fixed in macOS Sequoia 15.7.2,     macOS Sonoma 14.8.2. An attacker with physical access may be able to view deleted notes. (CVE-2025-43410)

Note that Nessus has not tested for these issues but has instead relied only on the operating system's self-reported version number.

  - The issue was addressed by adding additional logic. This issue is fixed in macOS Sequoia 15.7.3. An app     may be able to bypass launch constraint protections and execute malicious code with elevated privileges.
    (CVE-2025-43320)

  - A logic issue was addressed with improved restrictions. This issue is fixed in macOS Sonoma 14.8.3, macOS     Sequoia 15.7.3. An app may be able to access protected user data. (CVE-2025-43416)

  - A parsing issue in the handling of directory paths was addressed with improved path validation. This issue     is fixed in macOS Sonoma 14.8.3, macOS Tahoe 26.1, macOS Sequoia 15.7.3. An app may be able to access     sensitive user data. (CVE-2025-43463)
