Nutanix AOS : Multiple Vulnerabilities (NXSA-AOS-6.6.2.5)
critical Nessus Plugin ID 175007
Language:
Synopsis
The Nutanix AOS host is affected by multiple vulnerabilities .Description
The version of AOS installed on the remote host is prior to 6.6.2.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.6.2.5 advisory.- An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-0767)
- There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName.
X.400 addresses were parsed as an ASN1_STRING but the public structure definition for GENERAL_NAME incorrectly specified the type of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an ASN1_STRING. When CRL checking is enabled (i.e. the application sets the X509_V_FLAG_CRL_CHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or enact a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network. (CVE-2023-0286)
- zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference). (CVE-2022-37434)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
