Nutanix AHV : Multiple Vulnerabilities (NXSA-AHV-20230302.101026)

medium Nessus Plugin ID 206824

Language:

Synopsis

The Nutanix AHV host is affected by multiple vulnerabilities .

Description

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.101026 advisory.

 - A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

 - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
 (CVE-2023-45234)

 - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. (CVE-2023-50387)

 - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

 - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

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 AHV 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.
