Nutanix AHV : Multiple Vulnerabilities (NXSA-AHV-20230302.2024)

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-20230302.2024 advisory.- This flaw allows a malicious HTTP server to set super cookies in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain. (CVE-2023-46218)
- Use after free in tcpslice triggers AddressSanitizer, no other confirmed impact. (CVE-2021-41043)
- 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.See Also
