Synopsis

The Nutanix AOS host is affected by multiple vulnerabilities .

Description

The version of AOS installed on the remote host is prior to 6.10.1.12. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.10.1.12 advisory.

- A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system. (CVE-2025-32990)

- A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior. (CVE-2025-32988)

- A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite().
(CVE-2025-6395)

- OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.12 and earlier, when the `AuthType` is set to anything but `Basic`, if the request contains an `Authorization: Basic ...` header, the password is not checked. This results in authentication bypass.
Any configuration that allows an `AuthType` that is not `Basic` is affected. Version 2.4.13 fixes the issue. (CVE-2025-58060)

- 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)

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

Solution

Update the Nutanix AOS software to the recommended version. Before upgrading: if this cluster is registered with Prism Central, ensure that Prism Central has been upgraded first to a compatible version. Refer to the Software Product Interoperability page on the Nutanix portal.
