The remote host is running a version of macOS / Mac OS X that is 13.x prior to 13.7.6. It is, therefore, affected by multiple vulnerabilities:

  - A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity     expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat     can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could     lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the     environment and library usage. (CVE-2024-8176)

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

  - execute_filter_delta in archive_read_support_format_rar.c in libarchive before 3.7.5 allows out-of-bounds     access via a crafted archive file because src can move beyond dst. (CVE-2024-48958)

  - The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special     character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some     applications, an attacker can bypass a protection mechanism in which application access is granted only     after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be     used for signup). This occurs in email/_parseaddr.py in recent versions of Python. (CVE-2023-27043)

  - libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a use-after-free in xmlSchemaIDCFillNodeTables and     xmlSchemaBubbleIDCNodeTables in xmlschemas.c. To exploit this, a crafted XML document must be validated     against an XML schema with certain identity constraints, or a crafted XML schema must be used.
    (CVE-2024-56171)

  - When curl is asked to use HSTS, the expiry time for a subdomain might overwrite a parent domain's cache     entry, making it end sooner or later than otherwise intended. This affects curl using applications that     enable HSTS and use URLs with the insecure `HTTP://` scheme and perform transfers with hosts like     `x.example.com` as well as `example.com` where the first host is a subdomain of the second host. (The HSTS     cache either needs to have been populated manually or there needs to have been previous HTTPS accesses     done as the cache needs to have entries for the domains involved to trigger this problem.) When     `x.example.com` responds with `Strict-Transport-Security:` headers, this bug can make the subdomain's     expiry timeout *bleed over* and get set for the parent domain `example.com` in curl's HSTS cache. The     result of a triggered bug is that HTTP accesses to `example.com` get converted to HTTPS for a different     period of time than what was asked for by the origin server. If `example.com` for example stops supporting     HTTPS at its expiry time, curl might then fail to access `http://example.com` until the (wrongly set)     timeout expires. This bug can also expire the parent's entry *earlier*, thus making curl inadvertently     switch back to insecure HTTP earlier than otherwise intended. (CVE-2024-9681)

  - A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Ventura     13.7.3, macOS Sonoma 14.7.3. An app may be able to access removable volumes without user consent.
    (CVE-2025-24093)

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

  - A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. A machine-in-the-middle     attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how     OpenSSH mishandles error codes in specific conditions when verifying the host key. For an attack to be     considered successful, the attacker needs to manage to exhaust the client's memory resource first, turning     the attack complexity high. (CVE-2025-26465)

  - A stack overflow vulnerability exists in the libexpat library due to the way it handles recursive entity     expansion in XML documents. When parsing an XML document with deeply nested entity references, libexpat     can be forced to recurse indefinitely, exhausting the stack space and causing a crash. This issue could     lead to denial of service (DoS) or, in some cases, exploitable memory corruption, depending on the     environment and library usage. (CVE-2024-8176)

  - A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is     allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client     key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled     increase in memory consumption on the server side. Consequently, the server may become unavailable,     resulting in a denial of service attack. (CVE-2025-26466)
